NTC thermistors for temperature sensing and protection
STE NEWS
STE offers bead and extended-lead NTC thermistors for on-board and remote temperature sensing in power supplies, energy storage and other equipment.
Temperature feedback for equipment protection
Temperature-sensing NTC thermistors provide temperature feedback in power supplies, energy storage systems, home appliances, industrial controls and consumer electronics. They support temperature monitoring, overtemperature protection and temperature compensation.
Two package options for different sensing locations
STE offers epoxy-coated bead thermistors and extended-lead epoxy-encapsulated thermistors for on-board sensing, confined spaces and measurement points away from the control board.
Epoxy-coated bead NTC thermistors
- Compact construction: a small epoxy-sealed body with through-hole leads for direct mounting on a PCB.
- Fast response: low thermal mass supports a fast temperature response. Consistent resistance and B values support interchangeability.
- Typical uses: temperature sensing in confined spaces, including power supply boards, small-appliance control boards, power banks and battery module PCBs.
Extended-lead epoxy-encapsulated NTC thermistors
- Integrated construction: epoxy encapsulation and extended twin leads reduce the need for additional wiring.
- Flexible placement: the probe can be positioned in equipment enclosures, air ducts, and liquid or air sensing environments.
- Typical uses: temperature measurement away from the main control board, such as air ducts and remote points inside an enclosure.
Product features
- High sensitivity, stable temperature measurement and low temperature drift.
- Epoxy sealing for moisture resistance and resistance to aging during long-term operation.
- Custom development of resistance, B value and lead length.
- RoHS compliance, with applications across home appliances, new energy, industrial and medical equipment.
- Consistent batch performance for volume production, helping reduce production-line adjustment.
Typical applications
- Energy storage: temperature monitoring in BMS battery modules, PCS inverters and charging stations to support early warning of thermal runaway.
- Power supplies: on-board temperature sensing in server and switching power supplies, component overtemperature protection and circuit temperature compensation.
- Home appliances: temperature regulation and dry-heating protection in rice cookers, water heaters and air conditioners.
- Industrial controls: enclosure temperature sensing in variable-frequency drives and servo drives.
- Consumer electronics: temperature monitoring in lithium-ion battery packs and portable devices.
From temperature sensing directly on a PCB to measurement points reached by extended leads, STE can help select an NTC configuration for the equipment’s thermal management needs.
Guangdong Songtian Electronic Industrial Co., Ltd. supplies film capacitors, ceramic capacitors, varistors and NTC thermistors, with automotive product options.
Refer to the selected part’s datasheet for resistance, B value, temperature range and performance. Confirm the mounting method, contact medium and protection circuit in the actual application.
