NTC thermistor chips can be encapsulated with resin, glass, or metal, allowing the appropriate structure to be selected according to equipment design, installation location, and working environment.
The product covers a typical zero-power resistance range of 10Ω–10MΩ, with a typical B-value range of 2000K–6000K, allowing parameter matching for different temperature sensing circuits.
The typical thermal time constant range is 1–100 seconds. Equipment with different response requirements can select suitable specifications according to the actual temperature change speed.
Standard models typically support an operating temperature range of -55°C to +125°C. For special temperature environments, customized specifications can be further evaluated according to project requirements.
Packaged NTC Thermistors can be used for temperature detection in refrigerators, air conditioners, water heaters, and other appliances, providing temperature sensing signals according to internal temperature changes.
It can be used in automotive engine systems and battery thermal management systems to provide temperature monitoring input. For automotive applications with limited space or vibration conditions, the encapsulation structure needs to match the installation environment.
It is suitable for temperature monitoring in heavy machinery, chemical processing equipment, and large industrial refrigeration systems, helping monitor temperature changes during equipment operation or industrial processes.
It is suitable for temperature detection in high-density electronic circuits and power management systems. In compact electronic devices, encapsulation dimensions and installation methods need to be considered together with the overall structure.
NTC is an important temperature sensing component in our thermoelectric product portfolio. It can be used with Thermoelectric Coolers and related thermal management components to provide feedback signals for temperature control.
Different encapsulation methods solve different application requirements. When purchasing Packaged NTC Thermistors, we recommend selecting the suitable structure based on temperature range, installation method, working environment, and sensing location.
Resin encapsulation is suitable for temperature detection requirements in many conventional devices, including household appliances, electronic equipment, and some industrial applications.
Glass encapsulation protects the internal NTC thermistor element, making it more suitable for temperature detection applications with higher requirements for environmental stability.
Metal encapsulation emphasizes external protection and equipment integration capability, making it suitable for applications such as automotive systems and industrial equipment that require stronger structural adaptability.
Compared with directly using bare NTC chips, packaged products are more suitable for direct integration into actual equipment.

The working process of Packaged NTC Thermistors can be simply understood as:
Temperature change → NTC resistance change → Circuit detects resistance → Temperature information obtained
The NTC sensing element is installed inside the encapsulation structure and exchanges heat with the measured position. When the ambient temperature changes, the resistance value of the NTC changes accordingly. The control circuit reads the corresponding temperature signal according to the preset resistance-temperature relationship.
Therefore, actual product selection should not only consider the nominal resistance value but also include B-value, operating temperature range, thermal time constant, and circuit measurement requirements.
The selection of NTC should not be based on only one parameter. It is recommended to evaluate temperature, resistance value, B-value, response time, and encapsulation type together according to actual operating conditions.
First determine the actual temperature at the sensor installation position, including normal operating temperature and possible high or low temperature ranges, and then evaluate whether the standard model is suitable.
B-value and resistance value together determine the resistance-temperature characteristics of NTC. Different control circuits have different resistance requirements, so matching should be performed according to the actual circuit and temperature range.
If the equipment needs to detect temperature changes quickly, special attention should be paid to the thermal time constant. If temperature changes are relatively slow, selection can also be based on system control requirements.
If the equipment involves moisture, heat sources, mechanical vibration, limited space, or special installation requirements, the encapsulation material and structure should be confirmed in advance.
Our NTC production process includes metal oxide mixing, high-temperature sintering, electrode plating, customization, and encapsulation.
Metal oxides such as manganese, cobalt, nickel, copper, and iron are used as raw materials. Through material composition design, the foundation for corresponding thermistor characteristics is established.
The mixed materials are sintered at high temperatures to form the thermistor ceramic body. This process determines the temperature sensitivity characteristics of NTC products.
Gold or silver electrodes are plated on the ceramic body surface to provide electrical connection and maintain stable signal transmission.
According to different application requirements, parameters are matched and encapsulation methods such as resin, glass, or metal are selected, making NTC products more suitable for specific equipment and operating environments.
The customized capability disclosed on the official website can cover a wider temperature range of approximately -253°C to 1000°C. The actual capability needs to be confirmed according to project requirements.
We provide thermoelectric materials, Thermoelectric Coolers, NTC, and Temperature Controllers, allowing us to understand NTC applications from a more complete thermal management system perspective.
Our technical system covers materials, components, and solution design, and supports customization of key components. For projects where standard NTC products cannot fully match requirements, further communication can be carried out based on temperature range, resistance-temperature characteristics, and encapsulation methods.
We have continuously invested in advanced semiconductor cooling and temperature sensing technologies for more than 10 years. Our business has expanded into applications including optical communication, industrial medical equipment, intelligent automotive electronics, consumer electronics, and scientific research.
