Custom Epoxy NTC Thermistor Temperature Sensors Mass-Produced, Full Specifications of 5K 10K 100K 110K & B3977 Available

Recently, our factory has completed capacity expansion for the series of epoxy encapsulated NTC thermistor temperature sensors. The products support full customization of standard parameters including 5K, 10K, 100K, 110K resistance and B3977 value. Adopting epoxy resin sealing technology, the sensors feature waterproof, temperature-resistant and high-stability performance, widely applied in home appliances, energy storage, new energy, medical devices, industrial temperature control and other scenarios, with bulk shipments delivered to global customers.

This series of temperature sensors are integrally molded with epoxy resin potting, delivering multiple advantages over bare chip and sleeve encapsulated products:

1. Excellent protection performance: The epoxy colloid isolates moisture, dust and oil stains, delivering basic waterproof and moisture-proof performance to ensure long-term stable operation inside humid and dusty equipment.
2. Wide temperature adaptability: Operating temperature range covers -40℃ to 125℃. The colloid transfers heat evenly for fast temperature response and minor temperature measurement error.
3. Vibration-resistant stable structure: The fully cured integrated structure prevents wire breakage and component displacement during transportation and equipment vibration, reducing after-sales failure rates of end devices.

Built with high-precision NTC thermistor chips, the sensors offer standard resistance options of 5kΩ, 10kΩ, 100kΩ and 110kΩ, plus mainstream B-value 3977. We can customize special resistance, B-value, wire length and lead material according to customer drawings or samples, perfectly matching temperature control circuit designs of different devices.

Our epoxy NTC temperature sensors have been mass-supplied to terminal products across multiple industries:

• Home appliances: Water heaters, water dispensers, air conditioners, ovens, floor heating temperature control modules
• New energy & energy storage: Lithium battery pack temperature monitoring, energy storage converter temperature control
• Medical devices: Nebulizers, constant temperature physiotherapy instruments, testing equipment temperature probes
• Industrial automation: Mini temperature control modules, water pumps, motor overheat protection
• Export small home appliances: Supporting components for temperature-controlled small home appliances exported to Europe, America and Southeast Asia

We accept OEM & ODM bulk orders for overseas buyers based on drawings or sample parameter customization with stable lead time. All products comply with RoHS environmental standards to meet market access requirements of European and American regions.

Multiple inspection procedures are set throughout the whole production process, from NTC chip screening, lead welding and epoxy potting to resistance calibration:

1. Full inspection of resistance and B-value for every sensor before delivery, with tolerance strictly controlled within customer standards.
2. High & low temperature cycle aging test to verify resistance drift after long-term service.
3. Random sampling of waterproof insulation and voltage resistance test to eliminate risks of electric leakage and short circuit.

Equipped with mature automatic production lines, we accept small-batch sample orders and large-volume foreign trade orders. Our technical team provides circuit matching and model selection support to quickly deliver optimal temperature sensing solutions for clients.

With continuous expansion of the global temperature control equipment market, demand for high-precision and high-stability miniature temperature sensors keeps growing steadily. Our company will keep upgrading the epoxy NTC sensor product line, developing more customized sizes and special temperature-resistant models. With dual supply modes of standard stock and personalized customization, we deliver cost-effective temperature sensing component solutions for electronic equipment manufacturers worldwide.
