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.
