Coefficient of Resistance (TCR): Rated Power (on Suitable Heatsink): 20 Watts Rated Power (W/O Heatsink): 2 Watts * (See note below) Equivalent Parallel Capacitance: 1.0 pF Maximum Operating Voltage: 500V dc Withstand Voltage: 2000 V dc (Between terminals and heatsink) This small size non-inductive, high Operating Temperature Range: -55C to +155C power resistor is an innovative and Rated Ambient Temperature: -25C to +40C significant first for Tyco Electronics. Occupying a standard T0220 10R - 51K * With a 5.8C watt heatsink or better at a 25C ambient temperature, 20 watts can be dissipated A larger heatsink will allow the resistor to run at a lower temperature. package it is ideally suited to positions where high power dissipation, small size and tight tolerance are key design Characteristics Mechanical Test Condition Specification Life (Rated Power): 40C, rated power, 90 min-on, 30 min off, 1000 hours R (1.0% + 0.05 ohm) Life (Moisture Load): 60C, 90 - 95% RH, rated power, 90 min ON 30 min OFF, 1000 hours R (1.0% + 0.05 ohm) Temperature Cycling: Room temp > -55C 30 min > RT, 10 min 120C 30 min > RT 10 min, 5 cycles R (0.25% + 0.05 ohm) Short Time Overload: Rated voltage x 2.5, 5sec R (0.25% + 0.05 ohm) Soldering Heat: 350C solder pot, 3sec R (1.0% + 0.05 ohm) Insulation Resistance: DC 100 V, 1 min Over 1000M ohm Vibration: 10 - 50 Hz, 1 min, 20G, X-Y-Z 1 hour R (0.5% + 0.05 ohm) requirements. This series is an ideal solution for the output side of high speed pulse generators, a surge absorption resistor in switch mode power supplies and for monitors, display terminals, scientific workstations and other brown and white goods.
