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 to prevent costly damage and

promote a safe environment for electronic and

electrical

equipment, our single-use chip fuses provide performance stability

to support applications with current ratings from .5A up to 20A.

urrent

TE Circuit Protection also offers the telecom FT600 fuse for

fers

telecommunications applications. This telecom fuse helps comply

Figure 3 compared our straight wire element design 2410SFV

fuses with normal corrugating wire design fuse. The straight wire

element in air performs consistent fusing and cutting

Introduced PCB assembly technology into 2410SFV fuses design

and manufacture, we achieved on lead free completely and no
