MELFs Lower Operating Temperatures At Rated Power

For whatever application, the MLF and MLFM Series metal electrode leadless face

(MELF) resistors offer significantly lower operating temperatures at rated power compared to similar sized flat-chip resistors. In theory, their cylindrical form increases the surface area exposed to the air and disperses heat to the air more efficiently. The 0204 size runs at +55°C at 0.5W watt and the 0207 size runs at +67°C at 1W. The MLF and MLFM Series are available in 0204 and 0207 sizes in 0.25W watt, 0.5W, and 1W power ratings. Resistance values range from 1? to 10 M? with tolerances as low as 0.1% and TCRs as low as 10 ppm. Depending on size, tolerance, and TCR, pricing ranges from $0.018 to $0.47 each in full reel quantities. STACKPOLE ELECTRONICS INC., Raleigh, NC. (888) 734-7347.
