CW6 Series Aluminum Electrolytic Capacitors: High-Efficiency Energy Solutions for Harsh Industrial Applications

In today's rapidly evolving power electronics sector, efficient and reliable electronic components have become key drivers of technological innovation and industrial upgrading. YMIN's CW6 Series aluminum electrolytic capacitors, with their superior performance and reliable quality, demonstrate unique value in industrial power supplies, new energy, and automotive electronics.

Core Product Features

The CW6 Series aluminum electrolytic capacitors utilize an advanced snap-in design, achieving excellent electrical performance in a compact form factor. This series features an extremely wide operating temperature range, extending from -40°C to +105°C, ensuring stable operation in extreme environments. Rated voltages range from 350V to 600V DC, with capacitance values ​​from 82μF to 1000μF, provide engineers with a wide range of options.

One of the most compelling features of this series of capacitors is their exceptionally long service life—up to 6000 hours at 105°C. This performance far exceeds industry standards, allowing equipment to operate continuously for over eight months in high-temperature environments without concern for capacitor performance degradation. For industrial equipment that requires 24/7 operation, this feature significantly reduces maintenance costs and the risk of system failure.

Precision Manufacturing and Quality Assurance

The CW6 series utilizes meticulous manufacturing processes, using high-purity aluminum foil and an advanced electrolyte formulation, resulting in low leakage current. Furthermore, its loss tangent (DF) value does not exceed 0.2 at 20°C and 120Hz, demonstrating excellent high-frequency performance.

The product also exhibits excellent impedance characteristics, with the ratio of impedance at -25°C to impedance at +20°C not exceeding 5. Even at extremely low temperatures of -40°C, the impedance ratio remains below 8. This temperature stability ensures reliable operation in diverse climates, making it particularly suitable for outdoor applications.

Wide Applications

Photovoltaic Power Generation and New Energy Fields

In photovoltaic inverter applications, the CW6 series capacitors perform critical energy buffering and filtering functions. Its high withstand voltage (up to 600V) effectively handles voltage fluctuations generated by photovoltaic arrays, while its wide temperature adaptability ensures stable operation in extreme outdoor temperature fluctuations. Compared to conventional capacitors, the CW6's low ESR (equivalent series resistance) reduces energy loss and improves the conversion efficiency of the entire inverter system.

Industrial Drives and Automation

In industrial inverters, servo drives, and other equipment, CW6 capacitors provide stable DC support for power modules. Their high ripple current capability ensures reliability under frequent load fluctuations, while their compact size facilitates device miniaturization. This advantage is particularly evident in space-critical applications such as robotics and CNC machine tools.

Electric Vehicles and Charging Infrastructure

With the increasing popularity of electric vehicles, the CW6 series is increasingly used in on-board chargers (OBCs) and charging stations. Compliant with the AEC-Q200 automotive electronic component reliability standard, these products meet the stringent temperature, vibration, and life requirements of automotive electronics. Their high performance ensures a safe and efficient charging process, providing reliable hardware support for electric vehicle infrastructure.

Technological Innovation and Design Advantages

The CW6 series features numerous structural design optimizations. A special explosion-proof valve design safely releases internal pressure in abnormal situations, preventing housing rupture. Furthermore, the insulation performance between the terminals and the housing has been rigorously tested, demonstrating no abnormalities when a 2000V AC voltage was applied between the terminals and an insulating snap ring for one minute, ensuring safe operation.

The product also offers significant advantages in frequency characteristics. Its ripple current withstand capability increases with increasing frequency: the coefficient is 0.8 at 50Hz, 1 at 120Hz, and reaches 1.4 above 10kHz. This makes the CW6 particularly suitable for high-frequency applications such as switching power supplies, providing an ideal choice for modern high-efficiency power supply designs.

Reliability and Durability Testing

YMIN conducted rigorous durability testing on the CW6 series. After applying the rated ripple current and voltage for 6000 hours at 105°C, the capacitance change rate remained within ±20% of the initial value, the loss tangent value remained within 200% of the initial specification, and the leakage current still met the initial specification. These data demonstrate the product's performance stability after long-term use.

In addition, the product has passed high-temperature storage testing—after 1000 hours of storage at 105°C, all parameters still meet stringent requirements. This outstanding aging resistance reduces inventory pressure for equipment manufacturers and extends the effective life of end products.

Environmental Protection and Compliance

The CW6 series fully complies with the RoHS Directive and contains no restricted hazardous substances, demonstrating YMIN's commitment to environmental protection. Furthermore, the product's design utilizes recyclable materials, aligning with the circular economy and helping customers achieve green manufacturing goals.
