150 Ohm NTC Thermistor Temperature Sensor 

The 150 Ohm NTC Thermistor Temperature Sensor is a high-precision Negative Temperature Coefficient (NTC) resistor designed for accurate temperature sensing, thermal compensation, and overheating protection in electronic circuits. It has a nominal resistance of 150 Ohms (150Ω) at 25°C, making it suitable for applications that require fast temperature detection, high sensitivity, and reliable thermal monitoring.

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 enables electronic circuits and microcontrollers to accurately monitor temperature and respond by controlling cooling systems, regulating battery charging, activating protection circuits, or triggering alarms when abnormal temperatures are detected.

Manufactured using high-quality semiconductor ceramic materials, the 150 Ohm NTC Thermistor provides excellent thermal sensitivity, rapid response time, low power consumption, and long-term electrical stability. Its durable construction ensures consistent performance even in demanding industrial and consumer electronic applications.

The thermistor features a through-hole radial lead design, allowing easy installation on printed circuit boards (PCBs), prototype boards, and embedded electronic systems. Its compact size makes it suitable for space-constrained electronic devices while ensuring dependable operation over an extended service life.

The 150 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 found in lithium battery packs, SMPS power supplies, LED driver circuits, motor controllers, HVAC systems, home appliances, automotive electronics, industrial automation equipment, medical devices, robotics, and consumer electronics, where accurate temperature monitoring is essential for safety and performance.

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

Whether you are designing a temperature-controlled system, repairing electronic equipment, developing an IoT device, or creating a DIY electronics project, the 150 Ohm NTC Thermistor Temperature Sensor delivers reliable performance, accurate temperature measurement, and long operational life.

Working Principle

The thermistor operates based on the Negative Temperature Coefficient (NTC) principle:

• At 25°C, the thermistor has a resistance of 150Ω.

• As the surrounding temperature increases, its resistance decreases.

• As the temperature decreases, its resistance increases.

• The resistance variation is measured by a control circuit or microcontroller.

• The measured resistance is converted into temperature data.

• Based on the detected temperature, the system can activate cooling fans, regulate charging circuits, control heating elements, or provide overheating protection.
