Core Features

Ultra-compact size and fast response It features an epoxy bead‑type package, with a compact probe size that accommodates installation in the tight spaces of automotive applications. Additionally, its short thermal conduction path ensures rapid temperature response, achieving measurement accuracy of ±0.5°C, thereby providing reliable data support for small‑scale temperature control systems.
Excellent insulation and protection performance Epoxy encapsulation offers high insulation, moisture resistance, and oil‑resistance, enabling it to withstand the humid, oily, and mildly corrosive conditions of automotive environments. It effectively protects the internal chips, ensuring stable and reliable long‑term operation.
Automotive-grade durability The lead wires are made of high- and low-temperature‑resistant, aging‑proof materials, capable of withstanding the temperature fluctuations and vibration‑impact typical of in‑vehicle environments. They are resistant to embrittlement and fracture, offer a long service life, and comply with automotive electronics standards.
Flexible adaptation and customization : Lead wire length, wire diameter, and electrical parameters (resistance value, B‑value) can all be customized to meet the integration requirements of various in-vehicle devices, and the product can be used via direct soldering or plug‑in connections.

Typical application scenarios

Cell Temperature Monitoring in New Energy Vehicle Battery Management Systems (BMS)
Temperature acquisition for vehicle-mounted electronic control units (ECUs) and small power modules
