KEMET C4AQ DC-Link Capacitors
KEMET C4AQ DC-Link Capacitors use a polypropylene metallized film dielectric in a rectangular plastic box design with resin sealing and radial wire terminals. These capacitors provide self-healing behavior, low loss, low equivalent series inductance, high ripple current capability, and stable performance in high-frequency DC-link circuits. The C4AQ DC-Link capacitors feature an operating temperature range from −55°C to +105°C and a capacitance range from 1µF to 210µF. These devices come with capacitance tolerance of ±5% and ±10% and a maximum rated voltage of 1,500VDC. Typical applications include DC filtering, DC-link stages, power electronics, motor drives, renewable energy systems, and automotive power systems.
