Description
MJS fuse
s
have been used for Tip and Ring protectio
n in telecommunication circuits
.
And they continue to be used in legacy designs. However, with advent of new issues
of IEC/UL 60950 and Telcordia GR
-
1089(Issue 3).
MJS fuses may no longer meet all
test requirements, depending on the end product c
ircu
it design.
I
t is recommended
that Types RJS and SMP be evaluated for all new telecommunication applications.
