High Temperature Film Capacitor for Automotive

The Murata High Temperature Film Capacitor (FH series) can be used for continuous operation at temperatures of 125°C.
The capacitor is provided with a self-healing function for use in that high temperature range. Therefore, it is optimal for the converters and motor-drive inverters of eco-friendly cars that require a high temperature guarantee.

Introduction

Currently, film capacitors commonly used for automotive applications are generally guaranteed up to 105 °C. Murata has recently developed a new high heat resistant film material. Using this material, we commercialize a high heat resistance film capacitor that can be used continuously at 125 °C with Shizuki Electronic Co., Inc. Although there was a high heat resistance film capacitor in the past, there was a concern that the self-healing function is hard to work at high temperature and short-circuit failure may result. On the other hand, the product has a self-healing function in high temperature range.

Conventional film capacitors
  • Guarantee 105℃ continuous or less in general (PP)
  • Very limited functional self-healing at high temperature ranges, leading to a short mode failure (PPS and PEN )
High temperature capacitors (New Products)
  • Enable to use at 125℃ continuous
  • Functional self-healing at high temperature ranges, leading to an open mode failure
