Vishay Intertechnology has introduced a new AEC-Q200 qualified thick film power resistor in the compact, low-profile SOT-227B package for mounting on a heatsink. Available with an optional NTC thermistor for internal temperature monitoring and pre-applied phase change thermal interface material (PC-TIM) for more efficient mounting, the MCB ISOA200 offers high pulse handling capability and high power dissipation up to 200 W at an 80°C bottom case temperature.

Built on an exposed alumina substrate instead of a metal tab, the device lowers costs and weight for automotive, industrial, avionics, military and space applications, serving as a precharge, discharge, active discharge or snubber resistor. For applications subject to high and repetitive pulse surges, the resistor can handle high energy pulses up to 140 J for 0.1 s and is multipulsed tested. Additional custom testing options for the device are also available. Samples and production quantities are available now, with lead times of 12 weeks.
