TeleLink Fuse
Qualification Data
The F1250T and F1251T meet the following test conditions per GR 1089 without additional series resistance.
However, in-circuit test verification is required. Note that considerable heating may occur during Test 4 of the
Second Level AC Power Fault Test.

Notes:
•
•
•
Power fault tests equal or exceed the requirements of UL 60950 3rd edition.
Test 4 is intended to produce a maximum heating effect. Temperature readings can exceed 150 °C.
Test 2 may be dependent on the closing angle of the voltage source. Fuse is characterized at 50° to 70°. Closing angles
approximating 90° may result in damage to the body of the fuse.
Use caution when routing internal traces adjacent to the F1250T and F1251T.
