NTC is known as a negative temperature coefficient thermistor, which is made by thoroughly mixing and sintering ceramic materials with manganese cobalt nickel oxide. It has the characteristics of small fluctuations in resistance-temperature characteristics and a fast response to various temperature changes.

Introduction: Varistors are generally used in parallel in circuits. When the voltage across the resistor changes sharply, the resistor shorts out, causing the current fuse to blow, thus providing protection. Varistors are commonly used in circuits for over-voltage protection and voltage stabilization. Parameters to understand in circuit design: 1. Varistor voltage UN (U1mA): This is usually represented by the voltage across the varistor when a direct current of 1mA flows through it, indicating whether it is conducting. This voltage is referred to as the varistor voltage UN. The varistor voltage is also commonly denoted by the symbol U1mA. The error range for the varistor voltage is generally ±10%. In testing and practical use.

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.
