Understanding Diode Type NTC Thermistors

Diode type NTC thermistors (negative temperature coefficient thermistors) exhibit a decrease in resistance as temperature rises. This characteristic allows them to effectively measure and monitor temperature changes, making them invaluable in numerous industrial and consumer applications. The relationship between temperature and resistance is typically non-linear but can be accurately modeled using specific equations.

Applications of NTC Thermistors

NTC thermistors are extensively used in applications such as:

• Temperature Measurement: Used in digital thermometers and HVAC systems to provide accurate temperature readings.
• Temperature Compensation: Employed to stabilize circuits by compensating for temperature fluctuations.
• Inrush Current Limiting: Utilized in power supplies to limit inrush current during device startup.

According to a report by MarketsandMarkets, the global thermistor market is projected to grow from USD 1.32 billion in 2020 to USD 2.17 billion by 2025, driven largely by the increased demand for NTC thermistors in the automotive and consumer electronics sectors.
