High frequency and high temperature resistant capacitors
Dielectric materials for high-temperature capacitors
For example, the high melting temperature (T f > 1400 C) and T g (>550 C) of alkali-free glasses as well as their unique disordered molecular structures make them high-temperature resistant []. Furthermore, the glasses always have the advantages of defined composition, formability, homogeneity, easy processing and easy modification.

The ESR (Equivalent Series Resistance) of Capacitors
Essentially, it represents the internal resistance of an actual capacitor, which is an inherent characteristic of all capacitors, even those considered to be of high quality. For anyone to understand: if I were to tell a friend, who has no idea about electronics, at a bar counter what ESR is, I would say something like "It represents the losses of a capacitor and increases …
High Temperature Film Capacitor
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.

Ripple current and its effects on the performance of capacitors
In most capacitors, the equivalent series resistance is dependent on operating temperature and frequency. The ripple current degrades a capacitor by raising its internal temperature. The failure rate of capacitors is directly related to the temperature of operation, and operating capacitors at high temperatures shortens their life.
