A thermistor is a type of linear component that is sensitive to temperature. Its resistance value changes with temperature variations, which is why it is called a thermistor.
Thermistors are commonly used for temperature sensing, as their resistance changes in response to temperature variations. They are useful for measuring the temperature of the environment or equipment. With advantages such as small size, fast response time, high sensitivity, and accuracy, thermistors are widely applied in various electronic products.
However, prolonged use of thermistors, or the use of low-quality ones, can lead to failures that negatively impact electronic products.
Failures of Thermistors
Increased Temperature Error: The primary function of a thermistor is temperature measurement. When a thermistor fails, its readings may become inaccurate, leading to an increased temperature error.
Failure to Read Temperature Values: When a thermistor is damaged, it may fail to provide any temperature readings, making it impossible to monitor or control temperature.
Short Circuit: In some cases, a thermistor may develop a short circuit, which could cause overcurrent and overheating.
Abnormal Resistance Values: Under normal conditions, a thermistor’s resistance should change in accordance with temperature fluctuations. However, when a thermistor is faulty, its resistance may become abnormal and fail to correctly reflect temperature changes.
Adverse Effects of Thermistor Failures on Electronic Products
Failure of Temperature Control: Many electronic products rely on thermistors for temperature control. When a thermistor fails, accurate temperature measurements become impossible, causing temperature control to fail. This could lead to overheating or overcooling issues.
Device Damage: Certain electronic products, such as CPUs and power supplies, are sensitive to temperature changes. If a thermistor failure causes the temperature to rise or drop beyond safe limits, it may damage these devices.
Safety Hazards: Some electronic products, like electric vehicle batteries, require precise temperature control to operate safely. A thermistor failure that disrupts temperature regulation could lead to accidents or safety issues.
In summary, thermistor failures can have serious adverse effects on electronic products. It is crucial to regularly check and replace thermistors to ensure the proper functioning of electronic devices.
