Product Overview
The 1/4W 1/6W PTC Linear Thermistor is a precision-engineered temperature sensing component designed for stable, predictable, and reliable thermal control. Unlike conventional thermistors that may fluctuate or drift over time, this PTC (Positive Temperature Coefficient) thermistor delivers a smooth and linear resistance response, allowing your system to “feel” temperature changes with clarity and consistency.
Imagine a heating system that reacts exactly when it should—no delay, no overshoot, no instability. Whether integrated into household appliances, industrial control boards, or smart electronics, this thermistor ensures your temperature control system behaves like a finely tuned instrument rather than a rough switch.
Compact in size yet powerful in performance, it is built for engineers and manufacturers who need dependable thermal feedback without adding complexity or cost.
Usage
It is wildly used to temperature control,temperature measure and temperature compensation for communications, automobiles, instruments, computers, house appliances etc.
Application of PTC Linear Thermistor Temperature Control
Temperature measurement and control of household and autombile air-condition, refrigeratory, icebox,water heater, drinking through, radiator, dishwasher, disinfector, washing machine drying mac.
Product Features
Manufacture in physical technology with PTC material to ensure good stability.
The resistance is increasing linearly with the temperature increasing to enable the circuit design to be sample without linear compensation.
Can work under the -40°C~180°C
Good compatibility.
Fast detect on temperature and high sensitive.
Small size and durable structure that can use in various motion sensor, Standard outlook( meet with the standard of R) resistance size ) that can adapt to automated installation of printed circuit board
Can replace PT 100 &PT1000 platinum resistance under 180°C
