935C2W5K-F

**Type 935C, Polypropylene Capacitors for High Frequency Filtering High Current Ca p acitors for Switchin g Power Supplies** 

**Typ** e 935 metallized polypropylene capacitors are designed for **flte** ring applications in switching power supplies that operate **in t** he 20-100 kHz range. Their low ESR, high current and high **cap** acitance gives them an advantage over general purpose types. **This** series is UL recognized for construction only under UL File **Num** ber E128034(N).
