RF Shielded/Watertight
Panel Mount Type
Radio frequency shielded fuseholders eliminate possible transmission or
reception of RF signals through the hole in the chassis in which the fuse-
holder is mounted. These fuseholders comply with the watertight con-
struction requirement of MIL-PRF-19207 and the Shock-Safe require-
ments of IEC 60065 and 60127-6. A rubber O-ring and conductive gas-
ket maintain RF shielding and watertight construction.
SPECIFICATIONS:
The basic fuseholder used is the
345 603 Shock-Safe holder.
