Using the LC filter in Figure 27, the TPA3101D2 EVM passed the FCC Part 15 Class B radiated emissions test
with 21 inch speaker wires. Quasi-peak measurements were taken for the 4 standard test configurations, and the
TPA3101D2 EVM passed with at least 14-dB margin. A plot of the peak measurement for the horizontal rear
configuration is shown in Figure 30.

Inductors used in LC filters must be chosen carefully. A significant change in inductance at the peak output
current of the TPA3101D2 will cause increased distortion. The change of inductance at currents up to the peak
output current must be less than 0.1 mH per amp to avoid this. Also note that smaller inductors than 33 mH may
cause an increase in distortion above what is shown in preceding graphs of THD versus frequency and output
power.
Capacitors used in LC filters must also be chosen carefully. A significant change in capacitance at the peak
output voltage of the TPA3101D2 will cause increased distortion. LC filter capacitors should have DC-voltage
ratings of at least twice the peak application voltage (the power supply voltage) and should be made of X5R or
better material. In all cases, avoid using capacitors with loose temperature ratings like Y5V.
