1.2K PTC Positive Temperature Thermistor MZ5

RWF 500

The 1.2K PTC Positive Temperature Coefficient Thermistor MZ5 is a temperature-sensitive resistor that exhibits an increase in resistance as the temperature rises. With a nominal resistance of 1.2K ohms at room temperature, it is commonly used in applications for overcurrent protection, temperature sensing, and circuit stabilization. The MZ5 model is ideal for use in circuits where thermal protection is needed. When the temperature exceeds a certain level, the resistance of the thermistor increases, thereby limiting the current and protecting sensitive components from overheating or electrical surges. This thermistor is widely used in power supplies, motor controllers, and other electronic devices requiring thermal regulation and protection.

Product Description

MZ5 PTC thermistor is a typical temperature sensitive semiconductor resistor. When the temperature exceeds a certain value (Curie temperature), its resistance increases step by step with the increase of temperature.

Specifications

Its temperature coefficient of resistance is 10-100 times larger than that of metal, and it can detect the temperature change of 10-6 ?;

PTC thermistor

The working temperature range is wide. Normal temperature devices are suitable for-55? ~ 315?, high temperature devices are suitable for higher than 315? (up to 2000? at present), and low temperature devices are suitable for-273? ~ 55?;

It is small in size and can measure the temperature of voids, cavities and blood vessels in the organism which can not be measured by other thermometers;
