Virtually every industry under the sun depends on temperature sensors to measure and monitor the ambient temperature in a variety of applications.One of the most popular temperature sensor designs available is the NTC thermistor, sometimes referred to as a negative temperature coefficient thermistor.The model B57621C473K62 is a type of thermistor used for a variety of temperature measurement and control applications.

Application field

NTC thermistors offer several benefits that make them applicable in a wide range of industries, including automotive, medical, telecommunications and consumer electronics. In particular, the B57621C473K62 has a high sensitivity, fast response time, low power consumption and long-term stability, making it well-suited for near-real-time temperature readings in a variety of applications. In automotive applications, the B57621C473K62 is used as a sensor for engine control systems, fuel injection systems, ABS brakes and air conditioning systems. In medical applications, it is used to measure and maintain body temperature.

Working principle

The B57621C473K62 is a type of NTC thermistor, which means that its resistance decreases as temperature rises.The thermistor is made of a special type of ceramic material which exhibits a predictable change in electrical resistance when exposed to a change in temperature. This change is known as the B-parameter, and is a measure of the temperature coefficient, or the degree to which the thermistor\'s resistance changes with a temperature change.The resistance of the B57621C473K62 has a temperature coefficient of -1.2 ohms per °C, meaning that for every degree Celsius its temperature rises, its resistance decreases by 1.2 ohms.This enables the B57621C473K62 to be sensitive to temperature changes of as little as 0.1°C.

The B57621C473K62 thermistor is an electronic component with three terminals. Its resistance when used in an open circuit (no current is flowing through the thermistor) is known as its cold resistance, and its resistance when current passes through the thermistor is known as its hot resistance.The thermistor is usually connected in a series to a voltage source, current source, or both. This causes a small voltage or current to flow through the thermistor, enabling it to detect changes in temperature and provide an analog or digital output signal, depending on the type of circuit used.

The B57621C473K62 thermistor operates over a wide temperature range, from -55°C to +150°C. Its typical accuracy is ±1°C, making it well-suited to a variety of temperature sensing and measurement applications.Its small size and low power requirements make it suitable for use in low-cost, portable products.

The B57621C473K62 NTC thermistor is a reliable and versatile temperature sensor used in a multitude of industries and applications, and is an indispensable component of any temperature measurement and control system.
