A disc type NTC (Negative Temperature Coefficient) thermistor is a robust, ceramic-based semiconductor device designed for precise temperature measurement, compensation, and control applications. Its name derives from its distinctive round, disc-like shape, which offers a large surface area for enhanced thermal response and stability. The core material—typically a mixture of metal oxides (e.g., manganese, nickel, cobalt)—exhibits a predictable decrease in electrical resistance as temperature rises, making it ideal for monitoring dynamic thermal environments.
