High Precision Waterproof Epoxy Encapsulated NTC Thermistor
Our small black head epoxy encapsulated NTC thermistor features a high-sensitivity semiconductor ceramic chip as the core sensing component, sealed with epoxy resin to form a compact black probe. Standard resistance specifications include 5K, 10K, 20K, and 50K with 1% or 2% tolerance options. Equipped with tinned copper lead wire and PVC insulation for easy welding onto PCBA. This temperature sensor is ideal for mass production in small household appliances, providing stable real-time temperature collection within equipment.
Key Features
Compact small black head structure suitable for installation in narrow internal cavities
Epoxy resin fully encapsulates chip to block dust and resist slight water splashes
Multiple common resistance values available from stock for fast sample delivery
Flexible lead length options to match different assembly positions
Stable resistance variation curve ensures accurate temperature feedback for heating control
Production Technology
Manufacturing processes include ceramic chip sorting, silver electrode printing, lead welding, epoxy vacuum potting, curing, resistance screening, and insulation testing. Vacuum potting eliminates internal bubbles within the epoxy coating to prevent water penetration. Finished products undergo resistance sorting to classify precision grades, ensuring consistent performance for household mass production.
Working Principle
NTC thermistors feature a negative temperature coefficient: resistance decreases significantly as temperature rises. When installed in household heating appliances, the thermistor transmits real-time resistance data to the control board. The mainboard converts resistance values into temperature readings, then adjusts heating power to prevent overheating or insufficient heating.
