MZ6 Series PTC Thermistor – Dedicated for Overheat Protection

Product Introduction

The MZ6 series is a special-purpose PTC thermistor designed for overheat protection, which can accurately sense temperature changes of the surrounding environment and electronic components. Featuring compact size and low heat capacity, it responds rapidly to temperature rise and real‑time monitors overheating abnormalities of switching power supplies, power devices and other equipment.

Working Principle

Under normal ambient temperature and operating conditions, the resistance Rp of the PTC thermistor is lower than the reference resistance Rs, and the output voltage remains at a low level.

When the ambient temperature exceeds the rated protection temperature, the PTC resistance rises sharply and far exceeds Rs. The output voltage increases instantly to trigger the rear control circuit and activate overheat protection, realizing effective equipment safety protection.

PRODUCT FEATURES

Complete structural types: standard MZ6 through-hole type and MZ6T wire harness type, suitable for various installation scenarios.
Wide protection temperature range: 60℃~170℃ with multiple temperature specifications optional.
Fast temperature rise response for early warning of overheating risks.
Stable material performance with excellent aging resistance and low attenuation during long-term continuous operation.
Compact and miniaturized design enables flexible layout and easy installation & fixation.
Self-recovering overheat protection; automatically resets after temperature drops without manual operation.
Mature manufacturing process and impact resistance, ensuring high reliability for complete machine matching.

APPLICATION

Overheat protection for switching power supply modules;
Power electronic equipment such as motors, transformers and inductors;
Power semiconductor devices including MOSFETs, IGBTs and more;
Temperature monitoring and overheat protection for motor coils and windings.
