Thick Film Power Ceramic Resistors

What's Thick Film Power Ceramic Resistors?

Thick Film Power Ceramic Resistors have displayed several key advantages in demanding high voltage situations, including both continuous-wave and pulse applications. These include radar and broadcast transmitters, x-ray systems, defibrillators, lasers, and high voltage semiconductor process equipment applications, where resistors must handle peak voltage anywhere from 20 to 80 kV. Typical applications include current limit in capacitor charge/discharge, crowbar, and tube-arc circuits. In these uses, Thick Film Power Ceramic Resistors provide low inductance, high average power per unit size, stability at high voltage, and durability at extreme peak-power levels.
