The function of NTC (Negative Temperature Coefficient) thermistors.
2025-01-02
NTC thermistors are temperature-sensitive resistors with a negative temperature coefficient. The resistance value decreases as the temperature increases. The materials used are semiconductors with a high negative temperature coefficient. These resistors are widely used in switch power supplies, UPS power supplies, electronic ballasts, temperature sensors, and automatic heating regulators, among other applications. Below, I will introduce three functions of thermistors in surge absorption, temperature measurement, and temperature compensation.

Introduction to NTC Thermistors with Negative Temperature Coefficient
2020-11-09
Thermistors are very common resistors. A thermistor is a semiconductor component whose resistance value is highly sensitive to temperature. Its main characteristic is that the resistance value changes with temperature. There are many types of thermistors. Today, we will focus on NTC (Negative Temperature Coefficient) thermistors.

Selection and Precautions for Varistors
2020-04-13
Before selecting a varistor, it is important to understand the following relevant technical parameters: The rated voltage refers to the voltage value across the varistor under specified temperature and direct current conditions. The leakage current is the current value flowing through the varistor when the maximum continuous direct current voltage is applied at 25°C. The rated voltage is the peak voltage across the varistor when subjected to an 8/20 current pulse. The current capacity indicates the peak current when a specified pulse current (8/20μs) waveform is applied. Surge environment parameters include the maximum surge current Ipm (or maximum surge voltage Vpm and surge source impedance Zo).
