PTC thermistor working principle: PTC thermistor (positive temperature coefficient thermistor is a self-recovery fuse) is a semiconductor resistor with temperature sensitivity. Once it exceeds a certain temperature (Curie temperature), its resistance valu

We introduce the over-current maintenance application of polymer PTC resettable fuse: 1.PTC effect Say that a kind of data has PTC (Positive Temperature Coefficient) effect, that is, positive temperature coefficient effect, which only means that th

Matters needing attention in the use of chip fuses: 1. Maintain the current for normal operation of the circuit. When selecting a model, you need to determine the normal current of the circuit to select the corresponding type of chip fuse. The oper

A PTC thermistor is a resistor. A certain amount of heat will occur when current flows through it. The effect of the amount of PTC thermistor consumption on temperature is indicated by the dissipation constant. It refers to the dissipation of the temperat

PTC thermistor for degaussing circuit. It is characterized by no contact, no noise and long product life. The product is used in the demagnetization circuit of colorful CRT, effectively demagnetizing the CRT shading plate that is magnetized due to the inf

The difference between chip fuse and glass tube fuse: 1. In terms of cost, SMD fuses will be cheaper. 2. In terms of structure, chip fuses are more widely used, and glass tube fuses are only used in specific occasions. 3. In terms of function, SM

PTC thermistors are also called resettable fuses. Are PTC thermistors the same as PTC heater products? What is the difference between PTC thermistor and PTC heater? The working principle of PTC thermistor is different from that of PTC heater:

Tablet computers are digital products used by most people today. They can use the functions of most desktop computers and are widely used. The tablet computer is mainly composed of a built-in lithium ion battery (power supply), a main control board and an

The polymer PTC thermistor is a conductive polymer material with positive temperature coefficient. The most obvious difference between it and the fuse is that the former can be used repeatedly. Both products can provide over-current maintenance effect, bu

There are many types of ptc thermistors. As a temperature measurement, there are usually glass-sealed type epoxy type small head enameled wire type. As the temperature measuring part of the induction cooker, glass sealed type and other accessories are usu

Both PTC and NTC are thermistors, which can be divided into many types according to different temperature coefficients. NTC thermistor and PTC thermistor are the two most commonly used types. Although both are thermistors, there are certain differences be

PTC thermistor is a sensitive element, which is divided into positive temperature coefficient PTC thermistor and negative temperature coefficient thermistor (NTC) according to different temperature coefficients. The basic characteristic of the thermistor
