LKX Series Aluminum Electrolytic Capacitors: Power Guardians of High-Reliability Electronic Systems

As modern electronic devices evolve towards higher efficiency, miniaturization, and higher reliability, aluminum electrolytic capacitors, as key passive components, have a direct impact on the stability and lifespan of the entire system. YMIN's LKX series aluminum electrolytic capacitors, with their exceptional high-temperature tolerance, superior electrical performance, and long service life, are an ideal choice for various power supply systems and industrial control applications.

Excellent High-Temperature Performance and Long Life

The LKX series' most notable features are its exceptional high-temperature operating capability and exceptionally long service life. These products can operate continuously for 7,000 to 12,000 hours in harsh environments up to 105°C, far exceeding the standard requirements for conventional electrolytic capacitors. This exceptional temperature resistance is the result of YMIN's breakthrough innovations in electrolyte formulation, aluminum foil etching technology, and packaging processes.

The product utilizes a specialized electrolyte system with extremely low high-temperature volatility and excellent thermal stability, ensuring consistent performance in high-temperature environments. Furthermore, the high-purity aluminum foil undergoes a precision etching process, creating a large effective surface area and achieving high capacitance density within a compact package. The packaging utilizes high-temperature-resistant materials and a comprehensive sealing structure to effectively prevent electrolyte drying and environmental corrosion.

Excellent Electrical Performance

The LKX series offers a wide voltage range (35-450V DC) and capacitance value options to meet the needs of diverse application scenarios. In terms of electrical performance, this series offers outstanding performance: leakage current is strictly controlled within a range of 0.01CV to 0.02CV + 10μA, ensuring efficient energy storage; and the loss tangent remains at an excellent level of 0.08-0.25, depending on the voltage level.

Of particular note is the product's impedance characteristics. At -40°C, the LKX series' impedance ratio (Z(-40°C)/Z(20°C)) is controlled within a range of 3-6 times, significantly exceeding conventional products and ensuring stable system operation over a wide temperature range. Regarding high-frequency characteristics, the product provides detailed frequency correction coefficients, maintaining stable performance across the entire frequency range from 120Hz to 100kHz.

Strong Ripple Current Handling Capability

A significant advantage of the LKX series is its exceptional ripple current handling capability. Thanks to its optimized internal structure and low ESR design, it can handle high ripple currents ranging from hundreds of mA to several amps. The ripple current capability adjusts with frequency, with the frequency correction coefficient ranging from 0.8 at 50Hz to 1.5 at 10kHz. This wide-bandwidth capability adapts to a wide range of switching power supply operating frequencies.

In practical applications, this robust ripple current handling capability means the LKX series can effectively smooth power output, reduce voltage fluctuations, and provide a clean and stable power supply environment for sensitive electronic components. This feature is particularly important in high-frequency switching power supplies.

Strict Quality Assurance and Reliability Verification

The LKX series has undergone rigorous durability testing. At 105°C, under rated voltage and rated ripple current, the product's capacitance change rate, loss tangent, and leakage current all remained within specified limits. The capacitance variation rate for 35-100V products is controlled within ±25%, and for 160-450V products, it's even controlled within ±20%. This stability ensures the reliability of the equipment over long-term use.

The products have also passed high-temperature storage testing, demonstrating that all parameters remain within specification after 1000 hours of storage at 105°C under no-load conditions. This stability ensures long-term inventory and backup of the equipment, reducing production and warehousing risks for customers.

Wide Applications and Industry Value

Industrial power systems are a primary application area for the LKX series. In devices such as PLCs, industrial computers, and servo drives, LKX capacitors provide filtering and energy buffering for power modules. Their long life reduces equipment maintenance and improves production line efficiency. The LKX's reliability advantage is particularly evident in industrial scenarios with 24/7 continuous operation.

In the communications infrastructure sector, the LKX series plays a key role in applications such as base station power supplies, server power supplies, and network equipment. The product's high-frequency characteristics and low impedance ensure stable operation of communications equipment in complex electromagnetic environments. The high power density requirements of 5G base stations perfectly match the performance characteristics of the LKX series.

New energy and power electronics applications are another key area. The LKX series provides reliable DC link capacitor solutions for devices such as photovoltaic inverters, wind turbine converters, and UPS systems. Its high voltage rating (up to 450V DC) and excellent temperature characteristics make it suitable for the harsh operating environments of new energy equipment.

In automotive electronics systems, despite extremely stringent operating environment requirements, the LKX series, through optimized design, can meet the requirements of some automotive electronics applications. In components such as on-board chargers and DC-DC converters, LKX capacitors provide stable performance.

In the consumer electronics and home appliance sectors, while cost is more sensitive, the demand for reliability remains undiminished. The LKX series provides a cost-effective solution for power modules in appliances such as air conditioners, washing machines, and TVs.

Technological Innovation and Manufacturing Processes

YMIN has extensive technical expertise in aluminum electrolytic capacitors. The advanced electrolyte technology used in the LKX series offers higher conductivity and improved temperature stability. Optimized aluminum foil etching technology creates a more uniform and dense dielectric oxide layer, improving the product's breakdown voltage and reliability.

Automated equipment and a strict quality control system on the production line ensure product consistency. From aluminum foil cutting and winding to impregnation and packaging, every step is precisely controlled. The impregnation process, in particular, utilizes vacuum impregnation technology to ensure that the electrolyte fully penetrates the core, reducing internal resistance and inductance.

Selection Guidance and Technical Support

Selecting the right capacitor model is crucial for design engineers. The LKX series provides detailed technical parameters and dimensions, allowing engineers to comprehensively consider factors such as voltage requirements, capacitance, space constraints, and operating environment.

During the selection process, key considerations include operating temperature range, rated voltage margin (a 20-30% margin is recommended), ripple current requirements, and expected service life. For high-frequency applications, special attention should be paid to the product's ESR and impedance-frequency characteristics.

YMIN provides professional technical support services to help customers optimize circuit designs and maximize the performance advantages of the LKX series. The company also offers customized services, adjusting product parameters and specifications to meet specific customer needs.

Environmental Adaptability and Reliability Design

The LKX series was designed from the outset to meet the reliability requirements of various harsh environmental conditions. The products can withstand extreme temperature fluctuations from -40°C to +105°C, and their temperature coefficients have been carefully optimized to ensure stable performance throughout the entire temperature range.

In terms of seismic performance, the products utilize a special internal structure and reinforcement measures to withstand a certain degree of mechanical vibration and shock. This makes the LKX series particularly suitable for use in vibration-prone environments such as industrial equipment and automotive electronics.

In terms of moisture and dust resistance, the products' specially designed sealing structure effectively prevents the intrusion of moisture and dust, enhancing reliability in harsh environments.
