Type 935C, Polypropylene Capacitors for High Frequency Filtering
High Current Capacitors for Switching Power Supplies
Type 935 metallized polypropylene capacitors are designed for
filtering applications in switching power supplies that operate
in the 20-100 kHz range. Their low ESR, high current and high
capacitance gives them an advantage over general purpose types.
This series is UL recognized for construction only under UL File
Number E128034(N).
Highlights
- Low ESR
- High current
- High capacitance
- Self healing
- UL recognized
- Available with lugs
