Type 944L Low Inductance DC Link Capacitors

For Fast-switching Inverter Applications

Type 944L DC Link capacitors are specifically designed for fast

switching power conversion applications. Their low inductance

construction and low-loss winding technology make them ideal for

the next generation of high power-dense inverter and converter

designs. Their rugged plastic case with integrated mounting flanges,

threaded stud or insert termination options, allow for easy, secure

mounting. This series is ideal for DC Fast EV Charging and for high

power solar inverters and motor drives.

Highlights

• Designed for higher switching frequencies

• Up to 60% lower ESL (Equivalent Series Inductance)

• High ripple current

• M8 threaded stud and M5 insert termination options

• Integrated mounting flanges
