The TAH20 is a completely encapsulated thick film resistor in the TO220 package outline. Rated for 20 watts @ 25°C 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. FEATURES • 20 Watt Power Rating at 25°C Case Temperature • High Pulse Tolerant Design • Quick-snap Molded Package • Very Low Inductance Design • Resistor Package Electrically Isolated from Heat Sink • Low Thermal Resistance to Heat Sink @ RTH<6.25°C/W • Tube Packaging Available APPLICATIONS • Frequency Conversion • High Frequency Balancing • Snubbers TAH Series SPECIFICATIONS Electrical Resistance Range: 0.05Ω to 10KΩ, other values available upon request Tolerance: ±5% std. 1% Available on request Temperature Coefficient: Referenced to 25°C, ΔR taken at +105°C; 1 to 10Ω: ±(100ppm+0.002Ω)/°C 10Ω & up: ±50ppm/°C Max Operating Voltage: 350V Dielectric Strength: 1,800 VAC Power Rating: 20W @ 25°C case temperature; see derating curve, below Insulation Resistance: 10GΩ min. Momentary Overload: 2x rated power for 5 seconds where applied voltage ≤1.5 times max. operating voltage. ΔR ± (0.3% + 0.001Ω) 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.
