463D Series - Metallized Polytetrafluoroethylene (PTFE) Capacitor

High Temperature Film Capacitors Data Sheet

Extreme High Temperature Polytetrafluoroethylene (PTFE or Teflon®) Metallized Capacitors

The Electrocube 463D series is part of a designated line of capacitors specially designed and optimized for high temperature applications subject to AC and pulsing signals. Proudly made in the U.S., it offers high frequency operation, high current and stability in miniature package able to handle high surge currents without degrading. It’s a rugged, non-inductively wound metallized capacitor with high temperature outer wrap and epoxy endfill manufactured with proprietary processes that allow for successful use in high temperature environments. Created with high-grade materials, design and manufacturing, engineers prefer the 463D series for any extremely high temperature applications such as avionics, wind generation, high power applications, “down the hole” exploration and turbines.
