## Description
The Molex MPN 213864-2633 is a wire-leaded Negative Temperature Coefficient (NTC) ring thermistor sensor cable assembly from the 213864 product range, engineered for precise surface temperature measurement and thermal management. Featuring a nominal resistance of 10 kOhms at 25°C with a tight resistance tolerance of ±2% and a B-constant of 3964K (±1% tolerance), this sensor provides reliable and repeatable temperature feedback. The device exhibits a temperature coefficient of resistance of -4.4%/°C, a thermal time constant of 5 seconds in air, and a dissipation constant of 1 mW/K with a maximum power rating of 100 mW.
Designed for robust physical integration, the assembly incorporates a ring lug terminal potted with thermally conductive epoxy, facilitating secure surface mounting onto chassis, heat sinks, or fastener posts while ensuring efficient thermal coupling. The unit is equipped with 75 mm wire leads, supporting an extended operating temperature range from -40°C to +150°C (limiting to -40°C to +105°C when utilized with the integrated Micro-Lock Plus connector).
This NTC thermistor assembly is well-suited for demanding thermal sensing and compensation tasks across diverse sectors. Typical implementation circuits include over-temperature protection, thermal shutdown loops, and environmental monitoring in industrial HVAC systems, consumer appliances such as refrigerators, electric ovens, and coffee makers, as well as computing hardware, vending machines, and printing equipment.
