398 Fuse Series, & 390 Fuse Series going Red Phosphorus Free.
Dear Valued Customer,
With regards to the above reference, this is a 30-day PCN starting 1
st
June. Littelfuse will be expanding
the roll-out of the conversion of the other TE5 fuse series fuses to Red Phosphorus free.
Affected Fuse series are as follows,
- 389, 396, 385, 391, 395, 397, 398, 390
The same existing part number will be used/active. This will be a running change in production on 30
th
June 2020.
There are no changes to the electrical characteristics and performance as well as the physical
dimensions as listed on the datasheet.
The only change being the Operating Temperature which will increase from the present “-40degC to
85degC” to “-40degC to 125degC” .The type of resin (polyamide) will remain unchanged.
For distinction between the existing and future Red-Phosphorus fuses, the fuse cap and housing color
will change from existing “Red-Brown” to “Black”.
See images below for illustrative purposes.
