## Description
The Molex MPN 213862-1635 is a negative temperature coefficient (NTC) thermistor cable assembly featuring a ring lug terminal topology designed for secure surface mounting and efficient thermal coupling. This component exhibits a nominal zero-power resistance of 10 kΩ at 25°C with a tight resistance tolerance of ±1%, alongside a B-constant of 3800K carrying a ±1% tolerance. The assembly incorporates a thermally conductive epoxy potting within the ring terminal to optimize heat transfer from mounting surfaces, yielding a dissipation constant of 1 mW/K in air, a thermal time constant of 5 seconds, and a temperature coefficient of resistance of -4.4%/°C.
Engineered for reliable performance across a broad operational envelope, the sensor supports a continuous operating temperature range of -40°C to +105°C when utilizing the integrated connector, and up to +150°C at the cable leads. The assembly features a free-hanging 150 mm lead length terminating in a Micro-Lock Plus connector (Part No. 5055650201), facilitating secure mating in space-constrained architectures. With a maximum power rating of 100 mW, the sensor complies with lead-containing substance regulations (SVHC compliant as of the February 2026 threshold).
This NTC ring terminal thermistor assembly is optimized for precise thermal management, temperature compensation, and heat detection in diverse environments. Typical application topologies include consumer electronics, commercial equipment such as ATMs and vending machines, white goods (refrigerators, electric ovens, freezers, and coffee makers), and industrial HVAC systems, where dependable surface temperature monitoring on chassis or heat-sink elements is required.
