(Release: 20200511) All active circuit parts in the Active EMI filter are now integrated into a single IC (in a 4 x 4 mm QFN package with 12 Vdc supply).

- The noise attenuation performance is 20~30dB from 100kHz to a few MHz, when installed in a real inverter system with 120 dBuV CE noises.
– 5kV surge test is passed.
– The whole circuit part is extremely small!
