Panasonic's EMI filters are in a "T" configuration, two inductors in a series, with a capacitor connected between them to ground. In the case of the ELK-EV, a varistor with its defined capacitance is connected from between the inductors to ground. The ELK-E and ELK-EV have a rated current up to 2A, while the ELK-EA has a maximum current rating of 5A. The ELK-E and ELK-EA have a rated voltage of 50V, while the ELK-EV rated voltage varies at 27, 22, or 12V depending upon the part. Cut-off frequencies available are from 0.2 to 500MHz with accompanying attenuation from -30 to greater than -50dB. The operating temperature range is from -20 to 85℃.< Back to Panasonic EMI/RFI Components
