Products Highlights
The FM48 input filter module enables designers to meet the conducted emission limits of EN55022 level B and FCC level B when used with Vicor’s 48 Volt 2nd Generation of DC-DC converters. FiltMods accept an input voltage of 36 to 76 Vdc with a transient withstand capability of 100Vdc for 100 msec. The FiltMods are packaged in an industry standard “quarter-brick” module measuring 2.28" x 1.45" x 0.5" and are available in either 8 or 12 Ampere capacity. Both versions may be on-board or in-board mounted for height critical applications. The FiltMods can be teamed with Vicor’s IAM48 for transient and surge protection.
