How to replace the thermistor when it is broken
Thermistor application Thermistor is widely used in various fields such as household appliances, electric power industry, communications, aerospace, etc., and its development prospects are extremely broad. Can a burned-out thermistor be replaced with a general resistor? Let’s analyze it for everyone below, and hope it will be helpful to everyone.
The typical characteristic of thermistor is that it is sensitive to temperature and exhibits different resistance values ββat different temperatures. The higher the temperature of the positive temperature coefficient thermistor, the greater the resistance value, and the greater the temperature of the negative temperature coefficient thermistor. When the temperature is high, the resistance value is lower, they belong to the semiconductor device, the thermistor resistance value is lower when the temperature is higher, they belong to the semiconductor device, it is recommended that you still look for the same specifications of the model, SMD thermistor factory, Use in accordance with the design drawings and follow the principles of use will accompany you with half the effort.
γγ Can the thermistor be short-circuited if it is broken?
Thermistors can be divided into two types:
1. The resistance value of the resistor increases with the increase of temperature, which is called positive temperature resistance (PTC). It is used in a circuit with capacitor charging, that is, when there is no current, it has a certain resistance, and when there is a current flowing through it has a temperature so its resistance is reduced, so that it can buffer the charging current.
Second, the resistance value of the resistance decreases with the increase of temperature. It is called negative temperature resistance (NTC). It is used in temperature monitoring, such as the temperature probe in the frequency converter and the temperature probe in the induction cooker. You think if it is short-circuited, it will only cause an alarm. If you want to shield, you can connect it to the equivalent resistance at room temperature, it is best to replace it. Hope it helps you.
