3216FF Series
New Ratings Offer Low
Heat-Rise in a Small
Package for High
Current Applications
Introducing the 3216FF Series
Now Available in Ratings as
High as 20 Amps
1. New Offerings
The 3216FF15-R and 3216FF20-R are designed to carry
high levels of current without excessive heat rise or
efficiency losses. These fuses meet the market trend for
increasingly smaller, higher current applications.
2. Space Savings
Designed specifically for space sensitive applications, these
fuses provide significant space savings compared to many
existing high-current SMD solutions.
3. Low Heat-Rise
With low resistance and a rugged construction that is ideal
for heat dissipation, these fuses will run exceptionally cool in
the presence of high currents and elevated ambient
temperatures.
4. Up to 40A Protection
These fuses have been successfully tested in parallel for
protection in applications where currents reach as high as
40A.
5. Low Resistance
Resistance is up to 40% lower than existing high-current
solutions meaning less efficiency loss in the circuit and lower
heat-rise.

The 3216FF High Current Chip
TM
fuses offer
low heat-rise in a small package. Ideal for
applications where space and temperature
are important considerations, this fuse was
designed to run cool in the presence of high
currents. It has been tested in parallel for
reliable protection of currents reaching up to
40A. It can be used to replace larger 15A
and 20A fuses without sacrificing protection
or heat-rise.
