PTC Thermistors, also known as Positive Temperature Coefficient Thermistors, are a type of temperature sensor. They are usually composed of a semiconductor material that acts as a resistor and changes its resistive value with a change in temperature. The B59801D100A40 is an NTC PTC thermistor that is commonly used in temperature sensing applications. This article will discuss the applications and working principle of the B59801D100A40.

The B59801D100A40 is a hermetically sealed thermistor with a chip size of 4.8mm x 4.3mm. It has a resistance of 100K Ω at 25°C, and its operational temperature range is from -40°C to 125°C. It has a thermal time constant of less than 4 seconds. This thermistor is highly reliable and is mostly used for temperature compensation and sensing in consumer home appliances. For example, in motorized ceiling fans, the B59801D100A40 is used to detect the ambient temperature and adjust the speed accordingly.

The working principle of the B59801D100A40 is simple. When the temperature rises, the internal resistance of the thermistor changes accordingly. This change is known as the “NTC effect” and means that the thermistor’s resistance increases as the temperature rises. When the temperature drops, the internal resistance of the thermistor decreases. The NTC effect is what makes it such a useful tool for temperature sensing applications.

The B59801D100A40 can also be used in various medical applications such as temperature sensing in infrared sources. It is also used for temperature compensation in remote control and wireless communication systems. It can also be used for temperature measurement in various toys and electronic games. Other applications include power control in computers, air conditioners, refrigerators, and home air purifiers.

In addition to the B59801D100A40, there are many other types of PTC thermistors available. The most common types are the Chip Sized PTC Thermistor, Radial Leaded PTC Thermistor, and Axial Leaded PTC Thermistor. Each of these types is designed to meet specific needs and applications. Before choosing a thermistor, one must understand their requirements and the type of sensor best suited for them.

In conclusion, the B59801D100A40 is a hermetically sealed PTC thermistor that is used for temperature sensing and compensation in various applications. Its small size and high reliability make it an ideal choice for many applications. Its working principle is based on the NTC effect, whereby its resistance increases with increasing temperature. The B59801D100A40 is thus a versatile and reliable thermistor for temperature sensing applications.
