What is an NTC Thermistor?
An NTC (Negative Temperature Coefficient) thermistor is a semiconductor ceramic that exhibits a logarithmic decrease in resistance with increasing temperature.
It is widely used as a temperature sensor in various fields such as automotive, industrial equipment, home appliances, and medical devices where temperature detection is required.

NTCRP Series Product Overview
This product is a glass-encapsulated NTC thermistor sealed in a PPS case. The case at the tip of the product has been made as compact as the smallest in the industry by resin injection molding. Depending on the environment/shape of the mounting location, you can choose from two types: rectangular type and cylindrical type. The rectangular type is suitable for mounting on flat surfaces such as square wires for motors and busbars, while the cylindrical type is ideal for wrapping round copper wires into bundles. If you have any questions about the installation method, please feel free to contact us, and our experienced technical staff will propose the optimal mounting solution for you.
The NTCRP series is a temperature sensor that uses fluorine-based wires and can be used in high-temperature oil.
The wire length can be specified from 150 to 300mm. It is possible to change the strip length of the tip, crimp the terminal, or attach a connector.

1. High precision
The NTCRP series can measure temperatures in a wide range from -40°C to 200°C. By changing the characteristics of the thermistor or fixed resistance, it is possible to finely adjust the desired temperature range with pinpoint accuracy.
2. Reliability Testing
1. Dry Heat Test: 200 C for 1,000 hours dwell time
2. Cold Test: -40 C for 1,000 hours dwell time
3. Thermal Shock Test: 1000 cycles from -40 C to 200 C in 30 min
4. Damp Heat cycling : 85 C / 85% relative humitity, dwell time 1,000 hrs
A NTC thermistor that can measure temperatures without lagging behind, even in automotive applications where temperatures rise rapidly from -40°C upto 200 C. The NTCRP series can withstand upper temperatures of 200°C, making it suitable for temperature sensing in automotive applications and industrial motors. It has tight measurement accuracy with minimal influence from the external environment.
