Torque 1 Nm Derating Power Rating Notes - The FPR Series Resistors must be attached to a suitable heatsink. The maximum internal resistor temperature is 130C. To specify an appropriate heatsink use the following formula : RqH = TMAX - ( P x RqR ) - TA P Where: RqH = Thermal Resistance of Heatsink ( K/W ) RqR = Thermal Resistance of Resistor ( K/W ) TMAX = Maximum Temperature of Resistor TA = Ambient Temperature of Heatsink ( C ) P = Power Through Resistor ( W ) Ordering Information Part Number - Resistance - Contact - Tolerance FPR 2-T218 0.068 Ohms A 0.5% Document Number: 64200 Revision: 20-09-10 For technical questions, contact: powertron@vishaypg.com www.powertron.de 1 FPR 2-T218 Powertron SPECIFICATIONS (continued) Temperature Coefficient 4000 +15ppm/K TCR-Shift (ppm/K) 200 0 -15ppm/K Limit 2 (3s) 50 Nominal DR/R Limit 1 (3s) -20 0 20 40 60 80 100 120 140 200 -8000 -40 50 2 0 100 -6000 20 -4000 100 5 -2000 150 10 2000 DR/R (ppm) table A 250 Resistance Value (mOhm) Temperature (C) Dimensions www.powertron.de 2 Dimension mm tol.
