Surface-mount Fuses – Fundamentals
Surface-mount Fuses
Fundamentals
Overview
TE Circuit Protection offers the widest selection of surface-mount
fuses available for addressing a broad range of overcurrent
protection applications. Helping
ng to prevent costly damage and
promote a safe environment
nt for electronic and electrical
equipment, our single-use chip fuses provide performance stability
to support applications with current
urrent ratings from .5A up to 20A.
TE Circuit Protection also offers
fers the telecom FT600 fuse for
telecommunications applications.
ons. This telecom fuse helps comply
with North American overcurrent
current protection requirements,
including Telcordia, GR-1089, TIA-968-A (formerly FCC Part 68),
and UL60950 3rd edition.
Multi-layer Design for Chip

The multi-layer design has the

Temperature Derating
A fuse is a temperature sensitive
nsitive device. Therefore, operating temperature will have an effect on fuse
f
performance and lifetime.
Operating temperature should
ould be taken into consideration when selecting the fuse currentt rating.

11
Fuse selection seems straightforward,
ghtforward, in that, you pick one which has a current rating just a bit higher
highe than your worstcase system
operating current. Unfortunately, it’s not that simple. There are derating considerations for operating current and application
temperature. Turn-on and other system operations (like processor speed changes or motor start up) cause current surges or
spikes that also require consideration when selecting a fuse. So selecting the right fuse for your application is not as simple as
knowing the nominal current drawn by the system.
Fuse Selection Flowchart
However, the basic considerations for fuse selection are shown in the flowchart presented in Figure 6. Following this flow chart
will help you select a fuse best suited for your application conditions.

Surface-mount Fuses – Slow-Blow Chip Fuses
Surface-mount Fuses
Slow-Blow Chip Fuses
Available in industry standard
rd 1206 and 0603 chip sizes,
TE Circuit Protection’s slow-blow
low-blow chip fuses help
provide
overcurrent
protection
tection
on
systems
that
experience large and frequent
ent current surges as part of
their normal operation.
The slow-blow chip fuse’s monolithic, multilayer design
helps provide some of the

Recommended conditions for hand soldering:
1. Using hot air rework station that can reflow the solder on both terminations at the same time is strongly recommended,
do not directly contact the chip termination with the tip of soldering iron.
2. Preheating: 150°C, 60s (min).
Appropriate temperature (max) of soldering iron tip/soldering time (max): 280°C /10s or 350°C / 3s.
