Film capacitors are capacitors that use plastic film as the dielectric. They have features such as good frequency and temperature characteristics, no DC bias, and high insulation resistance.
Currently, PP film capacitors commonly used for automotive/industrial applications are generally guaranteed up to 105°C. The capacitors we now introduce here are high-heat-resistant film capacitors (FH series) that can be used continuously at 125°C. We have commercialized these capacitors with Shizuki Electric Co., Inc. using a high-heat-resistant film material developed by Murata Manufacturing.
In addition, the high-heat-resistant film used in the FH series has a high dielectric constant. Therefore, another one of its features is that it is possible to reduce the size compared to conventional PP film capacitors.
