Stackpole’s MLF/MLFM is a series of metal film, surface mount MELF resistors. The MELF technology provides cooler operating temperatures than flat chip resistors at full rated power. For example, the MLFM1 will typically run more than 70°C cooler than the equivalent 1W 2512 size flat chip resistor and has a smaller footprint. The cool operating performance is possible due to the cylindrical shape and solderable end caps of the MLF/MLFM….
