Standard NTC Thermistor Ring Lug Temperature Sensors 10KOhm 3984 For Battery Management Systems
Description Of The Ring Lug Temperature Sensors
High stability lug temperature sensors is suitable for surface temperature sensing applications, especially when a high electrical insulation (rated to 2.7 kVAC) and good thermal contact with the surface is required. These sensors provide accurate and dependable surface temperature measurement across a wide temperature range and are designed for long-term, stable operation at a peak temperature of 150°C. The CWF103F3984FB150RC lug sensors incorporate a negative temperature coefficient (NTC) thermistor with two multi-stranded AWG26, 600 V rated, ETFE insulated, silver-plated copper wires mounted inside the barrel of a lug terminal. Mounting of the CWF103F3984FB150RC lug sensor can be accomplished by use of a M3.5 (#5 or #6) screw. The CWF103F3984FB150RC series meet both AEC-Q200 qualified and UL recognized. In addition to the off-the-shelf version, the CWF103F3984FB150RC series provides the designer with flexibility through electrical and mechanical customization options including an option for a 150°C rated automotive connector.
