NTC thermistors are temperature sensors typically manufactured using sintered bead technology with a negative temperature coefficient. The B57861S0302F040 NTC thermistor is a 30kΩ resistance at 25°C unit, with a low resistance and B constant 25/85 = 3977K. The part has high accuracy of ±0.4°C over a wide temperature range of -40°C to 135°C, making it an ideal choice for many applications. The Working Principle of the B57861S0302F040 NTC thermistor is based on resistance-temperature-dependent (RTD) relationships. When an NTC thermistor is exposed to a changing temperature, its electrical resistance alters as a result of the movement of energy in the form of thermally agitated electrons. This energy-to-resistance change is exerted by the core material of the thermistor, which is typically a sinter material.

The B57861S0302F040 has application in various sectors. It can be used to sense ambient temperature indoors or outdoors, in thermostat control systems, and it can also be integrated into medical equipment to monitor body temperature, for example, to regulate fever in infants. Similarly, in hot-cold water systems, the B57861S0302F040 can be used to detect the temperature of the water. In temperature control applications, the B57861S0302F040 NTC thermistors are used to measure and regulate the temperature of a system. Typically, they are connected to a circuit that acts as an on/off switch, switching a heating or cooling device when the temperature rises above or falls below a preset level.

The B57861S0302F040 NTC thermistor can also be used in smart sensors to identify the presence or absence of a specific object, which is especially helpful in industrial environments. For example, when an NTC thermistor is used in a gear-monitoring sensor, it can detect the presence of a gear by sensing changes in temperature. Additionally, the B57861S0302F040 NTC thermistor can be used to detect the presence of a gas, such as a combustible gas. The thermistor will change resistance as the gas concentration increases, enabling an alarm or other type of alarm system to detect the gas level.

The B57861S0302F040 can also be used in automotive sensors to detect the engine temperature, coolant temperature, and the temperature of the exhaust system. In addition, it can be used to measure the temperature of the oil and brake fluid in order to detect any leaks or malfunctions in the system. The thermistor is also used in air pressure switches, such as in turbochargers, to detect the pressure in the system. Furthermore, it can be used in power management systems, such as in batteries, to detect changes in temperature in order to maintain optimal performance.

The B57861S0302F040 NTC thermistor has many uses, from sensing ambient temperature for thermostat control to detecting gas levels in industrial and automotive sensors. The unit has a low resistance and wide temperature range of -40°C to 135°C, with a high accuracy of ±0.4°C. These characteristics make it an ideal choice for many applications.
