    NTC thermistors are essential components used in various temperature detection, compensation, and control circuits. They play a critical role in converting temperature variations into necessary electronic signals within circuits. With societal advancements, these components have found widespread applications in devices such as household air conditioners, car air conditioners, refrigerators, freezers, water heaters, water dispensers, heaters, dishwashers, disinfection cabinets, dryer, and in temperature measurement and control for medium and low-temperature drying boxes and constant temperature boxes. Given their extensive use, NTC thermistors must be adaptable to diverse environments and temperatures, particularly high humidity and high temperature conditions.

Traditionally, the outer insulating layer of thermistors is encapsulated with epoxy resin. However, epoxy resin has limitations due to its poor heat resistance and waterproof capabilities. It can withstand a maximum temperature of 200℃, with long-term usage generally restricted to below 125℃. To address these limitations, Shiheng Electronics has introduced a high temperature resistant and moisture proof NTC thermistor. This new thermistor significantly outperforms most existing NTC thermistors in terms of temperature and moisture resistance. It can function effectively in humid environments at temperatures up to 250℃ for extended periods. This product features a glass-encapsulated NTC thermistor and a high-temperature cement-encapsulated NTC thermistor, ensuring long service life and high practicality.

As the portable thermistor industry evolves, there is a growing trend towards smaller, safer internal components. This development also demands higher sensitivity, moisture resistance, and ease of installation for NTC temperature sensors. Nanjing Shiheng Electronics produces various types of glass-encapsulated NTC thermistors that meet these requirements. These thermistors are characterized by their compact size, high temperature measurement accuracy, fast response speed, good consistency, and interchangeability. They are suitable for use in high temperature and high humidity environments. Their encapsulation heads can be as small as 0.8mm, earning the description "the smallest encapsulation head in the entire network" from customers and receiving widespread acclaim.
