NTC Thermistor with Low Thermal Gradient for High Accuracy Temperature Measurement and Sensing in Automotive and Industrial Applications

NTCLE317E4103SBA NTC Thermistor from Vishay Intertechnology
Vishay's NTCLE317E4103SBA NTC Thermistor

Vishay Intertechnology has released a new epoxy-coated NTC thermistor with long PEEK-insulated, nickel-iron (NiFe) leads and a low thermal gradient. NiFe alloy of the Vishay BCcomponents NTCLE317E4103SBA sensor’s conductor wire delivers fast, high accuracy temperature measurement, sensing, and control in automotive and industrial applications.

 

Featuring the lowest thermal conductivity available on the market, the NTCLE317E4103SBA sensor’s conductor wire has excellent thermal decoupling that offers temperature measurement accuracy to ± 0.5 °C unlike other conductive wire materials like copper that can deviate by several degrees. Additionally, the device features a small maximum bead size diameter of 1.6 mm, resulting in a fast response time of less than 3 s in air. The 75 mm long and flexible radial leads help in special mounting or and fulfills assembly requirements too.

 

The NTCLE317E4103SBA provides high adhesive strength between its PEEK-insulated lead wires and encapsulating epoxy lacquer. This helps in improving reliability in high humidity conditions. With high accuracy and fast speed, it becomes apt for boilers, fire and smoke detectors, battery management systems (BMS) for battery packs, charge circuits, DC fan motors, seat heating, and HVAC sensors in cars, and printer heads.

 

The RoHS-compliant sensor offers resistance at +25 °C (R25) of 10 kΩ with curve tracking between 25 °C and 85 °C, and beta (B25/85) of 3984 K, with a tolerance of ± 0.5 %. The device features maximum power dissipation of 50 mW and operates over a wide temperature range of -55 °C to +150 °C.
