Screw Terminal Aluminum Electrolytic Capacitor | High Current DC-Link and Energy Storage for Industrial Systems
Screw terminal aluminum electrolytic capacitors are designed with cylindrical aluminum cases and threaded terminals, ideal for high ripple current DC filtering, energy storage, and snubber circuits in industrial-grade systems.
With ripple current ratings up to 20–60A RMS, they’re widely used in VFDs, UPS, welding machines, solar inverters, rail traction power, and EV chargers.
