FEATURES Surface Mount Power Resistors * Tolerance 1%-5% standard * Eleven wattage ratings * Six package sizes * Two mounting designs to accommodate your soldering process * Five power resistor technologies to optimize your operating performance: 1. Carbon and Ceramic composition for high inrush current, low inductance 2. Metal film for high ohmic value and low T.C. 3. Wirewound for inrush current combined with low ohmic values, down to 0.005 and close toleance for low T-C, low ohm values, high inrush or tight tolerance 4. Power film for high ohmic value and high wattage 5. Thick film for high voltage applications * Flexible J-bend terminations Standard pedestal mount Flexible J-bend Series RC0S2CA RC0R5DB RM0R7EA RF0S8BA RW1S0BA RF1S0CA RC1R0EA RP1S3CA RW1S5CA RP1S5CB RP1R5CB RW2S0CB RW2R0CB RP2S0DA RP2R0DA RW2S0DA RW2R0DA RP2R5DB RW3R0DB RP3R0EA RW3R5EA 500 Typical TCR for less than 0.1 SMD resistors (PPM/C) 400 300 200 100 0.02 0.04 0.06 Ohms RC Series: carbon/ceramic composition RF Series: metal film RW Series: wirewound Recessed-base mount RP Series: power film RM Series: thick film 0.08 0.10 Wattage 0.25 0.50 0.75 0.80 1.00 1.00 1.00 1.25 1.50 1.50 1.50 2.00 2.00 2.00 2.00 2.00 2.00 2.50 3.00 3.00 3.50 Ohms 2.2-5.6M 2.2-20M 1K-900M 0.30-10M 0.005-1K 1.0-10M 3.3-100K 1.0-1M 0.005-1.5K 1.0-1M 1.0-1M 0.005-5K 0.005-5K 1.0-1M 1.0-1M 0.005-5K 0.005-5K 1.0-1M 0.005-13K 1.0-1M 0.005-25K Length 0.394 / 10.01 0.655 / 16.64 0.811 / 20.60 0.246 / 6.25 0.246 / 6.25 0.394 / 10.01 0.811 / 20.60 0.394 / 10.01 0.394 / 10.01 0.407 / 10.34 0.407 / 10.34 0.407 / 10.34 0.407 / 10.34 0.455 / 11.56 0.455 / 11.56 0.455 / 11.56 0.455 / 11.56 0.625 / 15.88 0.625 / 15.88 0.811 / 20.60 0.811 / 20.60 Dimensions (in. / mm) Height 0.159 / 4.04 0.226 / 5.74 0.273 / 6.93 0.136 / 3.45 0.136 / 3.45 0.159 / 4.04 0.273 / 6.93 0.159 / 4.04 0.159 / 4.04 0.222 / 5.64 0.222 / 5.64 0.222 / 5.64 0.222 / 5.64 0.226 / 5.74 0.226 / 5.74 0.226 / 5.74 0.226 / 5.74 0.226 / 5.74 0.226 / 5.74 0.273 / 6.93 0.273 / 6.93 Width 0.159 / 4.04 0.273 / 6.93 0.273 / 6.93 0.136 / 3.45 0.136 / 3.45 0.159 / 4.04 0.273 / 6.93 0.159 / 4.04 0.159 / 4.04 0.226 / 5.74 0.226 / 5.74 0.226 / 5.74 0.226 / 5.74 0.24 / 6.10 0.24 / 6.10 0.24 / 6.10 0.24 / 6.10 0.273 / 6.93 0.273 / 6.93 0.273 / 6.93 0.273 / 6.93 Voltage 250 350 2500 200 50 350 500 350 75 350 350 100 100 500 500 100 100 500 200 750 350 MILITARY GRADE VERSIONS AVAILABLE: CONSULT FACTORY PERFORMANCE SPECIFICATIONS Part Number* Power (watts)* Maximum voltage 1% tol.
