2.4 NTC Ring Lug

The NTCALUG01A series resistors from Vishay® are ring lug style NTC thermistors. An NTC thermistor chip is soldered to 24-gauge stranded silver-plated copper leads with PTFE (polytetrafluoroethylene) insulation and insulated with epoxy coating. The insulated sensor is attached to a tin-plated copper ring lug. The lead wires are stripped, twisted and dipped in a tin-silver solder alloy. The NTCALUG01A103FLA specifically selected for this test has the following specs: Automotive AEC Q-200 qualified, 10-kΩ nominal resistance, 1% resistor tolerance, 1% B tolerance, and –40°C to 150°C operating range.
