SPECIFICATIONS Material Terminals: Tinned Copper Encapsulation: Silicone Molding Compound Electrical Resistance range: 1Ω to 15MΩ Standard Tolerances: 0.005%, 0.01%, 0.02%, 0.05%, 0.1%, 0.25%, 0.5%, and 1% Temperature Coefficient of Resistance, 0°C to 85°C: 1Ω to <10Ω: ±25 PPM/°C 10 Ω to <100Ω: ± 15 PPM/°C ≥100Ω: ±10 PPM/°C Operating Temperature Range: -65°C to 145°C Temperature Compensating TCR: from +80 through +6000 PPM TCR Matching: to ±0.5 PPM/°C at 25°C DERATING P Series Resistors must be derated for tolerances below 0.1% and for elevated ambient temperatures. Choose the curve corresponding to the desired tolerance. Determine the maximum allowed percentage of rated power from the graph based on the maximum ambient temperature expected during use. 100 Percent Rated Power 1" / 25.4mm min. Ohmite’s P Series Epoxy molded Precision Wirewound Resistors are designed to meet the exacting requirements of Military Specification MIL-R-93. The P Series offers high stability and low Temperature Coefficient of Resistance (TCR). These resistors offer tolerances as accurate as ±0.005% and Temperature Coefficients of Resistance (TCR) as low as ±2PPM/°C in a wide range of resistance values. 1.0%, 0.5%, 0.25% & 0.1% 80 0.05% 60 0.02% 0.01% 40 20 0.005% 0 0 20 145 65 85 105 115 125 60 80 100 120 140 160 40 Ambient Temperature, °C This product has been DISCONTINUED 40 Ohmite Mfg.
