340 Series RF Shielded / Watertight Panel Mount Fuse Holders for 3AB/3AG Fuses
RoHS
Compatible Fuses For 3AG and 3AB Fuses
Description
Radio frequency shielded fuseholders eliminate
possible transmission or reception of RF signals
through the hole in the chassis in which the
fuseholder is mounted. These fuseholders
comply with the watertight construction
requirement of MIL-PRF-19207 and the Shock-
Safe requirements of IEC 60127-6. A rubber
O-ring and conductive gasket maintain RF
shielding and watertight construction.
