## Description
The Molex 213865-2333 is an NTC ring terminal sensor cable assembly engineered for precise thermal management, temperature compensation, and surface temperature monitoring. Featuring a negative temperature coefficient (NTC) thermistor housed within a conductive ring lug, this assembly provides a secure mechanical fastener mounting style optimized for direct thermal transfer from heatsinks, chassis, and power components. The device exhibits a nominal zero-power resistance of 3 kΩ at 25°C with a tight resistance tolerance of ±2% and a B-constant of 3982K (±1% tolerance). With an integrated 75 mm lead length terminating in a reliable connector (utilizing Molex's Micro-Lock Plus system, part number 5055650201), the assembly accommodates installations in confined spaces and hard-to-reach locations across industrial and consumer electronics.
Constructed for robust performance, the assembly is potted with thermally conductive epoxy to protect the internal thermistor element while ensuring rapid thermal response times, characterized by a 5-second thermal time constant in air and a temperature coefficient of resistance of -4.4%/°C. The component operates across a temperature range of -40°C to +105°C when utilizing the connector interface, and supports a maximum power dissipation of 100 mW with a dissipation constant of 1 mW/K. This reliable thermal sensing solution is well-suited for demanding application environments including HVAC systems, white goods (refrigerators, electric ovens, and coffee makers), industrial automation equipment, power supplies, and internal chassis temperature monitoring in computing and peripheral hardware.
