EW3 Series Aluminum Electrolytic Capacitors: Cost-Effective Industrial-Grade Power Solutions

Product Overview and Technical Advantages

In modern industrial power systems, the choice of capacitor directly impacts equipment stability and service life. The EW3 series of aluminum electrolytic capacitors, launched by Shanghai YMIN Electronic Technology Co., Ltd., boasts superior performance and reliable quality, making them an ideal choice for applications such as industrial control and UPS power supplies. This series offers an operating temperature range of -40°C to +105°C, a rated voltage of 200-500V DC, and a capacitance range of 1000-33000μF, providing comprehensive power support for a wide range of industrial applications.

The EW3 series' most notable feature is its 3000-hour service life at 105°C, demonstrating its stability and durability in high-temperature environments. The use of high-quality electrolytic materials and advanced manufacturing processes ensures superior performance in harsh industrial environments.

Precision Design and Structural Features

The EW3 series embodies a commitment to continuous improvement in its mechanical design. The product is available in five diameters, ranging from 51mm to 101mm, each meticulously calculated and optimized. Screw terminals range from M5 to M8, with terminal diameters ranging from 13mm to 17mm, ensuring reliable connections while meeting the requirements of varying current levels.

For installation, the product features optimized torque parameters (2.2Nm to 7.5Nm) to ensure a secure connection while preventing damage from overtightening. The unique insulating sleeve design and 2000V AC insulation voltage test standard provide dual assurance for safe equipment operation. The capacitor housing is constructed of high-quality aluminum alloy, offering excellent heat dissipation and mechanical strength, ensuring stable performance in harsh environments such as vibration and shock.

Wide Applications

Industrial Control Systems

The EW3 series capacitors play a key role in industrial automation control systems. As power supply filtering and energy storage components, they effectively smooth voltage fluctuations, suppress electromagnetic interference, and provide stable power for precision control equipment such as PLCs and servo drives. Its rapid charge and discharge characteristics ensure instantaneous system response to sudden load changes, significantly improving control accuracy and system reliability.

UPS Uninterruptible Power Supply Systems

The EW3 series is particularly well-suited for UPS applications. In UPS systems, capacitors perform crucial functions such as energy buffering and voltage stabilization. When the mains power supply is abnormal, capacitors can promptly release stored energy, maintaining system voltage stability and ensuring uninterrupted operation of critical equipment. The product's excellent temperature characteristics enable it to maintain stable performance even in the high-temperature environments within UPS equipment, significantly enhancing system reliability.

Industrial Power Supply Equipment

The EW3 series demonstrates outstanding performance in industrial power supply equipment such as switching power supplies and variable frequency power supplies. Its low equivalent series resistance (ESR) effectively reduces power loss and improves power conversion efficiency. It can withstand high ripple currents and maintains stable performance during frequent charge and discharge cycles, extending the life of the power supply equipment.

Technical Innovation and Performance Features

Advanced Material Technology

The EW3 series utilizes high-purity aluminum foil and a specialized electrolyte formulation. Advanced etching and chemical conversion processes form a dense oxide film dielectric layer on the aluminum foil surface. This technology not only enhances the product's withstand voltage but also significantly improves its frequency and temperature characteristics. Special electrolyte additives effectively suppress gas generation and enhance high-temperature stability.

Scientific Ripple Current Handling Capability

This product offers excellent ripple current handling capabilities, automatically adjusting performance based on the operating frequency and ambient temperature. At 10kHz, the ripple current correction factor reaches 1.4, enabling the capacitor to effectively handle the high-frequency ripple current generated by high-frequency switching, reducing temperature rise and extending service life.

Stable Temperature Adaptability

The EW3 series exhibits excellent temperature characteristics. At -25°C, the capacity retention rate reaches 60%-70% of the capacity at +20°C. The temperature correction factor decreases with increasing temperature (2.7 at 40°C, 1.0 at 105°C), ensuring optimal performance across a wide range of ambient temperatures.

Strict Quality Control System

Each EW3 series capacitor undergoes a rigorous quality inspection process. Strict quality control is implemented at every stage, from raw material receipt to finished product shipment. The product has passed multiple reliability tests, including high-temperature load life testing, temperature cycling testing, and voltage withstand testing, ensuring its reliability in actual use.

In durability testing, after applying rated voltage at 105°C for 3000 hours, the capacitance change rate remained within ±20% of the initial value, the loss tangent value did not exceed 200% of the initial specification value, and the leakage current remained within the specified range. These test results fully demonstrate the product's stability during long-term use.

Engineering Application Recommendations

In actual applications, users are advised to select product specifications based on specific operating conditions. For applications with higher operating temperatures, appropriate derating should be applied to ensure product life. In high-frequency switching power supply applications, the product's ESR characteristics and ripple current handling capacity should be considered.

During installation, ensure proper wiring torque is maintained to avoid overtightening or undertightening. Ensure good heat dissipation from the capacitor to prevent local overheating that could affect product performance. When using multiple capacitors in parallel, pay attention to current sharing to ensure that each capacitor operates within a safe range.

After-Sales Service and Technical Support

Shanghai YMIN Electronic Technology Co., Ltd. provides customers with comprehensive technical support and service guarantees. The company boasts a professional technical team capable of providing comprehensive technical assistance, including product selection and application solution design. Furthermore, the company has established a comprehensive after-sales service system to ensure prompt resolution of any problems encountered during use.

Conclusion

The EW3 series aluminum electrolytic capacitors, with their excellent performance, reliable quality, and competitive pricing, have become a leading choice in the industrial power electronics field. Whether used in industrial control systems, UPS power supply equipment, or other power electronics devices, the EW3 series provides stable and reliable power support.

With the continuous advancement of industrial automation and increasingly stringent requirements for equipment reliability, the EW3 series will continue to create value for customers across various industries with its superior performance and reliable quality.
