Pi Filter Designer is a simple 3 element 50 ohm input and output impedance pi filter designing application, enable you to design simple lowpass filters by selecting from a variety of standard capacitor values either empirically or to suit what you have on hand.
The filter 3 dB cutoff frequency and required L1 inductance are automatically calculated and displayed. In addition, the user may select an additional capacitor value to put in parallel with both caps C1 and C2. In this app XL = XC = 50 ohms impedance. No other impedances can be calculated with this program.

Using this program:
Use the drop-down combo box to select the primary capacitor values for C1 and C2 and observe the cutoff frequency and required inductor for a 50 ohm inductive reactance at the cutoff frequency.

Use the second combo box on the right of the schematic to parallel other capacitor values with both C1 and C2 in the schematic. The capacitive reactance of the capacitors plus the inductive reactance of the displayed inductor always equals 50 ohms in this program.
