Type MJS
Lightning Surge Withstand Fuse
MJSD0199
MJS Fuses are primarily intended for
use in telecommunication circuit applica-
tions requiring low current protection with
high surge tolerance. They are typically
used to replace heat coil type devices.
They are designed to be placed between

MJS fuses guard protected circuitry against sustained overload or
short circuit conditions. Such sustained overloads may be generated by
accidental contact between utility cables and phone lines (power line
cross).
