EATON EFDKA DC-Link Capacitors
Eaton EFDKA Series DC-Link Capacitors use metalized polypropylene film to provide stable capacitance and low Equivalent Series Resistance (ESR) in high-frequency environments. These capacitors are optimized for high-ripple current handling and long operational life under elevated temperatures. The EFDKA series capacitors feature an operating temperature range from -55°C to +105°C and a voltage range from 450Vdc to 1200Vdc. These devices come with a capacitance range from 1uF to 200uF and self-inductance of <1nH/mm. Applications include automotive powertrains, industrial drives, solar inverters, and other high-power DC-link systems.
