Key Product Features: Built for Harsh Industrial Environments

The EW6 series capacitors are designed for demanding industrial applications and offer a number of exceptional features. With an operating temperature range of -40°C to +105°C, they offer stable operation in extreme temperature environments and are particularly well-suited for high-temperature industrial applications. With a voltage range of 350-500V DC and capacitance values ​​ranging from 1000 to 22000μF, they provide ample energy storage capacity for high-power applications.

Utilizing high-quality electrolytic materials and specialized processing, these products achieve a loss factor (DF) below 0.15, effectively reducing energy loss and improving system efficiency. Strict leakage current control (≤1.5mA or 0.01CV) ensures long-term capacitor stability and safeguards system operation.

The EW6 series' most notable advantage is its long service life of 6,000 hours, maintaining stable performance even under continuous full-load operation at temperatures as high as 105°C. This significantly reduces equipment maintenance frequency and lifecycle costs, creating significant economic value for industrial users.

Precision Design and Reliable Construction: Quality in Every Detail

The EW6 series also embodies meticulous mechanical design. Available in five diameters from 51mm to 101mm, each meticulously calculated and optimized to maximize performance within limited space. Screw terminals range from M5 to M8, with terminal diameters from 13mm to 17mm, ensuring reliable connections while meeting the requirements of varying current levels.

The terminal torque ratings are scientifically designed, ranging from 2.2Nm to 7.5Nm, ensuring a secure connection while preventing damage from overtightening. The unique explosion-proof design and insulation treatment enable the product to withstand 2000V AC insulation voltage tests, providing dual protection for system safety.

The capacitor housing is made of high-quality aluminum alloy with a special anti-corrosion surface treatment, ensuring excellent heat dissipation and mechanical strength. The interior is constructed of high-purity electrolytic paper and high-purity aluminum foil. Advanced winding and vacuum impregnation techniques ensure stable performance in harsh environments such as high temperature, high humidity, and vibration.

Wide Application Scenarios: Excellent Performance Proven Across Multiple Industries

Industrial Inverters and Variable Frequency Drives

The EW6 series capacitors play a key role in industrial inverters and variable frequency drives. As DC link capacitors, they effectively smooth the rectified DC voltage, suppress voltage fluctuations, and provide a stable DC power supply for the inverter. In variable frequency drive applications, the capacitors store and release energy to compensate for transient power demands, ensuring smooth motor startup and operation. Their low ESR characteristics are particularly suitable for high-frequency switching applications, effectively reducing switching losses and improving overall system efficiency.

New Energy Power Generation Systems

In photovoltaic inverters and wind turbine converters, the EW6 series capacitors perform crucial functions as energy buffering and power compensation. They smooth out power fluctuations caused by weather changes, ensuring stable, high-quality power delivery to the grid. Their high-temperature tolerance is particularly well-suited for the operating environments of outdoor power generation equipment, and their long-life design significantly reduces maintenance costs, improving the economic efficiency of power generation systems.

Industrial Automation Equipment

In precision equipment such as CNC machine tools, industrial robots, and automated production lines, the EW6 series provides stable power support for servo drive systems and control systems. Capacitors absorb transient high current surges, protecting delicate electronic components from voltage fluctuations, and ensuring high-precision and reliable operation.

Power Quality Improvement Devices

In power quality improvement devices such as UPS (uninterruptible power supply) systems, dynamic VAR compensation devices (SVGs), and active power filters (APFs), the EW6 series plays a key role in energy storage and power conditioning. Its rapid charge and discharge characteristics enable timely response to load changes, maintaining system voltage stability, improving power factor, and enhancing grid power quality.

Specialty Power Supply Systems

The EW6 series is designed to withstand frequent high-current surges in specialty power supplies, such as welding machines, electromagnetic heating equipment, and medical imaging equipment, while maintaining stable performance. After rigorous durability testing, the product demonstrated that even after 6000 hours of rated ripple current at 105°C, the capacitance change remained within ±20% of the initial value, and the loss tangent did not exceed 200% of the initial specification, demonstrating excellent durability.

Technological Innovation and Performance Advantages

Advanced Material Technology

YMIN utilizes high-purity aluminum foil and a specialized electrolyte formulation. Using nano-scale chemical formation technology, a dense oxide film is formed on the foil surface, significantly improving the product's withstand voltage and service life. Special electrolyte additives effectively suppress gas generation and enhance the product's high-temperature stability.

Scientific Ripple Current Handling Capability

The EW6 series offers excellent ripple current handling capabilities, automatically adjusting performance based on frequency and temperature changes. At a high frequency of 10kHz, the ripple current coefficient can reach 1.4, far exceeding conventional products. This feature enables the capacitor to effectively handle the high-frequency ripple current generated by high-frequency switching, reducing temperature rise and extending service life.

Intelligent Temperature Adaptability

The product boasts excellent temperature characteristics. At -25°C, the capacity retention rate reaches 60%-70% of the capacity at +20°C. The temperature correction coefficient decreases with increasing temperature (2.7 at 40°C, 1.0 at 105°C), ensuring optimal performance in a wide range of ambient temperatures.

Strict Quality Assurance

Each EW6 series capacitor undergoes rigorous factory testing, including withstand voltage testing, leakage current testing, and capacitance accuracy testing. The product complies with RoHS environmental directives and is ISO9001 certified for quality management systems, ensuring complete quality control from raw materials to finished product.

Engineering Application Advice and Technical Support

In actual engineering applications, users are advised to select product specifications based on specific operating conditions. For high-frequency applications, the product's ESR and ripple current characteristics should be considered. For high-temperature environments, the product's temperature rating and life expectancy should be considered. For compact equipment with limited space, smaller size specifications can be selected.

YMIN provides comprehensive technical support services, including application solution design, heat dissipation calculations, and installation guidance. Engineers and technicians can receive personalized product selection and application guidance based on the specific requirements of their equipment, ensuring the capacitors achieve optimal performance in the system.
