| The TAH20 is a completely encapsulated thick film resistor in the TO220 package outline. Rated for 20 watts @ 25C case temperature, these resistors are electrically isolated, and molded in a high temperature case. Designed for heat sink mounting, the symmetrical package is ready for use with snap-on style heat sinks (we recommend use of thermal grease). The TAH20 Series is very low induction, and available in a wide range of resistance values in standard 5% tolerance. 1% tolerance available by special order. SPECIFICATIONS Electrical Resistance Range: 0.05 to 10K, other values available upon request Tolerance: 5% std. 1% Available on request Temperature Coefficient: Referenced to 25C, R taken at +105C; 1 to 10: (100ppm+0.002)/C 10 & up: 50ppm/C Max Operating Voltage: 350V Dielectric Strength: 1,800 VAC Power Rating: 20W @ 25C case temperature; see derating curve, below Insulation Resistance: 10G min. Momentary Overload: 2x rated power for 5 seconds where applied voltage 1.5 times max. operating voltage. R (0.3% + 0.001) max. Terminal Material: Copper Terminal Plating: Lead Free Solder (97% Tin, 3% Silver) Mounting: Requires the use of a snap-on style heat sink. A thermal compound should be properly applied. Solder Process: The TAH20 cannot exceed 260C for more than 10 seconds during soldering process.
