DC-link capacitor with nice lowest ESR value

Today, we successfully shipped a batch of high-performance DC-Link capacitors specifically designed for inverter welders. This shipment includes 500 units of the 140μF/800VDC model with an ultra-low ESR of 0.3mΩ, and 300 units of the 200μF/800VDC model featuring an ESR of 0.5mΩ. Both models are engineered to deliver exceptional stability and efficiency in high-power applications.


These capacitors are built with robust film technology and are rated for operation across a wide temperature range of -40°C to +85°C, ensuring reliable performance even in demanding industrial environments. The low ESR values are critical for minimizing energy loss and heat generation, making them ideal for modern inverter-based welding equipment that requires precise power control.
Shanghai Rongtech Industry (Shanghai) Inc.,an experienced manufacturer in making capacitors.We take pride in delivering components that meet international standards, including IEC 61071. Before handling, please ensure the capacitors are fully discharged to guarantee safety.
This shipment marks another step forward in our commitment to providing high-quality, reliable power solutions for the welding industry. We look forward to supporting our customers with components that drive performance and innovation.
