47 Ohm NTC Thermistor Temperature Sensor 

The 47 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 variety of electronic circuits. It has a nominal resistance of 47 Ohms (47Ω) at 25°C, making it suitable for applications that require fast thermal response, reliable sensing, and stable long-term performance.

Unlike a conventional fixed resistor, an NTC thermistor changes its resistance according to the surrounding temperature. As the temperature increases, the resistance decreases in a predictable manner. This characteristic allows electronic circuits and microcontrollers to accurately detect temperature changes and perform functions such as activating cooling systems, regulating battery charging, controlling heating elements, or protecting sensitive components from overheating.

Manufactured using high-quality semiconductor ceramic materials, the 47 Ohm NTC Thermistor offers excellent temperature sensitivity, rapid response time, low power consumption, and consistent electrical performance over extended periods. Its durable construction ensures reliable operation even in demanding industrial, automotive, and consumer electronic applications.

The thermistor features a through-hole radial lead design, making it easy to mount on printed circuit boards (PCBs), prototype boards, and embedded electronic systems. Its compact size allows seamless integration into space-limited devices while maintaining dependable performance.

The 47 Ohm NTC Thermistor is commonly used in Battery Management Systems (BMS) to monitor battery temperature and prevent overheating during charging and discharging. It is also widely 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 accurate temperature monitoring is critical for safety and efficiency.

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

Whether you are designing an embedded control system, developing an IoT device, repairing electronic equipment, or creating a DIY electronics project, the 47 Ohm NTC Thermistor Temperature Sensor provides dependable temperature sensing, excellent stability, and long operational life.
