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. FEATURES • Wide Range of Precise Tolerances (±0.005% to ±1%). • Low Inductance. • RoHS Compliant. • Axial configuration convenient for PCB and hard wiring applications. 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 P Series 1.0%, 0.5%, 0.25% & 0.1% 80 0.05% 60 0.02% 0.01% 40 20 0.005% 0 0 20 65 85 105 115 125 145 40 60 100 120 140 160 80 Ambient Temperature, °C Ohmite Mfg.
