220 Ohm NTC Thermistor Temperature Sensor 

The 220 Ohm NTC Thermistor Temperature Sensor is a high-precision Negative Temperature Coefficient (NTC) resistor designed for accurate temperature measurement, thermal compensation, and overheating protection in a wide range of electronic circuits. It has a nominal resistance of 220 Ohms (220Ω) at 25°C, making it ideal for applications that require fast thermal response, high sensitivity, and dependable long-term performance.

Unlike a fixed resistor, an NTC thermistor changes its resistance according to the surrounding temperature. As the temperature increases, the resistance of the thermistor decreases in a predictable manner. This characteristic allows electronic circuits and microcontrollers to accurately detect temperature changes and perform functions such as controlling cooling systems, regulating battery charging, activating protection circuits, or monitoring equipment for overheating.

Manufactured using high-quality semiconductor ceramic materials, the 220 Ohm NTC Thermistor offers excellent thermal sensitivity, rapid response time, low power consumption, and stable electrical performance over extended periods. Its robust construction ensures reliable operation in demanding industrial, automotive, and consumer electronic environments.

The thermistor features a through-hole radial lead design, making it easy to install on printed circuit boards (PCBs), prototype boards, and embedded electronic systems. Its compact size allows convenient integration into compact electronic devices while maintaining consistent and reliable operation.

The 220 Ohm NTC Thermistor is widely used in Battery Management Systems (BMS) to monitor battery temperature and prevent overheating during charging and discharging. It is also commonly used in lithium battery packs, SMPS power supplies, LED driver circuits, motor controllers, HVAC systems, home appliances, automotive electronics, industrial automation equipment, robotics, medical devices, and consumer electronics, where precise temperature monitoring is essential for safe and efficient operation.

This thermistor is fully compatible with popular microcontroller platforms including Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and other embedded systems. When connected in a voltage divider circuit, the changing resistance can be measured using an analog input, allowing software to calculate the temperature accurately for monitoring, automation, and control applications.

Whether you are developing an embedded control system, designing an IoT device, repairing electronic equipment, or building a DIY electronics project, the 220 Ohm NTC Thermistor Temperature Sensor provides accurate temperature sensing, dependable performance, and long operational life.

Working Principle

The thermistor operates according to the Negative Temperature Coefficient (NTC) principle:

• At 25°C, the thermistor has a resistance of 220Ω.

• As the surrounding temperature increases, its resistance decreases.
