FILM RESISTORS MR Series: Metal Film INTRODUCTION RoHS ü FEATURES Metal Film Resistors are designed to provide MIL performance and reliability at a significantly lower cost. High grade materials make the much smaller space saver size available. Automated production assures uniform quality and low cost. •Temperature Coefficients: 25, 50, & 100PPM (1/4 watt standard is 50ppm) •Tolerance 1%, 0.5%, & 0.1% •DIN Style 44061 DERATING CURVE Dimensions (mm) 70°C Rated Load (%) 100 80 60 40 20 0 -55 155°C -30 0 SPECIFICATIONS Type MIL Style MR12 MR25 MR25M MR50 Rated Power (W) d±0.05 Resistance Range (W) 1/8 3.8 0.45 10-1M 200 20 250 1.6 20 0.6 0.5 1-10M 1/4 6.5 3.6 1.5 2.5 20 1/4 10-1M 1/2 9.5 3.5 20 0.7 1/2 6.3 2.5 20 1 2 11 16 4.5 5 1/16 RN55 1/8 MR50M MR100 RN65 3/4 MR200 RN70 1 Notes: H RN50 1/3 Lead(mm) D±0.3 70°C RN60 Body(mm) L±0.3 125°C 20 40 60 80 100 125 140 160 Ambient Temperature (°C) Standard tape Packing 400 T52 5000 500 T52 5000 200 400 T52 5000 10-2.4M 350 700 T52 2500 5.11-4.7M 350 700 T52 2500 20 0.6 0.8 5.11-2.4M 500 1000 T73 2000 20 0.8 5.11-5.11M 750 1000 T73 1000 Max.
