Data Book and Design Guide
Advantages include:
• Elimination of series line resistance enabling longer loop lengths
• Precise longitudinal balance allowing better transmission quality
• Robust surge performance which eliminates costly down time due to nuisance blows
• Greater surge ratings than resettable devices, ensuring regulatory compliance
• Non-degenerative performance
• Available in surface mount packaging which uses less Printed Circuit Board (PCB) real
Weaknesses
Because a fuse does not reset, consideration should be given to its use in applications
where multiple fault occurrences are likely. For example, AC strip protectors and ground
fault interrupting circuits (GFIC) are applications in which an alternative solution might be
more prudent.
Applications
Telecommunications equipment best suited for a fuse is equipment that requires surface
mount technology, accurate longitudinal balance, and regulatory compliance without the
use of additional series line impedance.
Selection Criteria
For circuits that do not require additional series resistance, the surge current rating (I
the TeleLink SM fuse should be greater than or equal to the surge currents associated with
the lightning immunity tests of the applicable regulatory requirement (I
For circuits that use additional series resistance, the surge current rating (I
TeleLink SM fuse should be greater than or equal to the available surge currents associated
with the lightning immunity tests of the applicable regulatory requirement (I
The maximum available surge current is calculated by dividing the peak surge voltage (V
by the total circuit resistance (R
