Description

Composite PTC Thermistor Varistor 30-50 OHM 115C 390V SPMZ11-10E300-500R/14D391

Description

The SPMZ11-10E300-500R/14D391 is a multifunctional circuit protection component that integrates a Positive Temperature Coefficient (PTC) thermistor with a Varistor (Metal Oxide Varistor, MOV) into a single composite package. With a resistance range of 30-50 Ω and a threshold temperature of 115°C, this device is designed to provide both overtemperature and overvoltage protection. It features a high voltage rating of 390V, making it suitable for use in compact electronic assemblies where space efficiency and reliable safety protection are critical.
