Operating Voltage * P R ( 500V MAX ) Insulation Resistance >1000 Meg-Ohm Inductance <10nH ( At the Standoff ) Environmental Performance D R Test Conditions Load Life ±1% + 0.05W 25°C, 90 min ON, 30 min OFF, 1000 hr Humidity Resistance ±1% + 0.05W 40°C, 90-95% RH, DC 0.1W, 1000 hr Temperature Cycle ±0.25% + 0.05W -55°C for 30 min, +155°C for 30 min, 1000 hr Solder Heat ±0.1% + 0.05W +350°C, 3s Vibration ±0.25% + 0.05W IEC60068-2-6 Mounting Notes - The PF2200 Series Thin Film Resistors must be attached to a suitable heatsink. Mount resistor using thermal grease to a clean, flat surface. Use a compression washer to provide 150 to 300 pounds ( 665 to 1330N ) of mounting force. Torque mount- ing screw to 8 in-lbs ( 0.9 N-m ). Mounting tab is isolated from both pins.

Without a heatsink the maximum power rating is 1W ( 1/2W for the PF2201 ). The maximum internal resistor temperature is 155°C ( 120°C for the PF2201 ). To specify an appropriate heatsink use the following formula : Where: R q H = Thermal Resistance of Heatsink ( °C/W ) R q R = Thermal Resistance of Resistor ( °C/W ) T MAX = Maximum Temperature of Resistor ( °C ) T A = Ambient Temperature of Heatsink ( °C ) P = Power Through Resistor ( W ) ( * ) R P T P R T H MAX R A = - - H H |
