T-Pad / H-Pad Resistance Calculator

This calculator requires the use of Javascript enabled and capable browsers. This calculator is designed to give resistor values for unbalanced T-pads, and for balanced H-pads. We suggest the use of the closest 1% tolerance resistors to the values shown. Attenuators beyond 40dB are not recommended and results are unpredictable. Enter the values for input impedance, output impedance and the desired attenuation. Click the Calculate button for the calculated resistance values. All input values are numeric.
