B57234S0509M000

NTC (Negative Temperature Coefficient) Thermistors are temperature sensors found in a variety of industries and applications. As the name implies, NTC thermistors are components that have a negative temperature coefficient; that is, as the temperature increases, the resistance of these sensors decreases. The B57234S0509M000 is a specific type of NTC thermistor that is often used in harsh environments. They can provide accurate measurements over a wide temperature range and are commonly used in automotive, consumer electronics, and appliance applications.

• Wide Temperature range: -40 to +125 °C
• Variable resistance from 9 to 9092Ohms
• High stability and excellent reliability

Applications

• Automotive electronics, such as coolant-level sensors and engine temperature sensors
• HVAC controls, such as temperature sensors
• Whitegoods, such as oven and refrigerator temperature sensors
• Factory automation, such as temperature monitoring of mechanical components

Working Principle

The B57234S0509M000 is a Negative Temperature Coefficient (NTC) thermistor, meaning as the temperature of the device increases, its resistance goes down. The resistance of the device is specified at only two temperature extremes (25°C and 125°C). The resistance of the device will change with any change in temperature from these specified extremes.

The B57234S0509M000 utilizes a nickel-metal base disc and is encapsulated in a PEN material to ensure reliable protection. The resistance of the thermistor is determined by the ratio of two internal components, a resistive material (typically a Cermet type such as Ni/Cr or Ni/Pt) and a Positive Temperature Coefficient (PTC) material (typically a Nickel Iron or Manganese Nickel alloy). This ratio of components is set to give an appropriate change in resistance as the device is heated or cooled.

The B57234S0509M000 thermistor is available in a range of operating temperatures from -40°C to +125°C and with an accuracies of up to ±0.5°C. The device is also available in a variety of ohmic values to match the needs of specific applications.

Conclusion

The B57234S0509M000 is a NTC thermistor designed for harsh environment applications. Its fast response time, high accuracy, wide temperature range, variable resistances, and high stability make it an ideal choice for automotive, consumer electronics, and appliance applications. Its simple working principle, utilizing two internal components for resistance variation, makes it easy to use and maintain.
