Four-port TeleLink Fuse
This hybrid Single In-line Package (SIP) protects four twisted pairs from overcurrent
conditions. Comprising eight TeleLink surface mount fuses, it is ideal for densely populated
line cards that connot afford PCB inefficiencies or the use of series power resistors. F0500T,
F1250T, F1251T versions are available.
* Interrupt test characterized at 50 to 70 phase angle. Phase angles approximating 90 may result in damage to the body of the fuse.
Notes:
The TeleLink SM fuse is designed to carry 100% of its rated current for four hours and 250% of its rated current for one second
minimum and 120 seconds maximum. Typical time is four to 10 seconds. For optimal performance, an operating current of 80% or
less is recommended.

Resistance changes 0.5% for every C.
Resistance is measured at 10% rated current.

Qualification Data
The F1250
Z8
and F1251
Z8
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.
* Test 5 simulates a high impedance induction fault. For specific information, please contact Teccor Electronics.
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.

Temperature Derating Curve
Operating temperature is -55 C to +125 C with proper correction factor applied.
Chart of Correction Factor
* Higher currents and PCB layout designs can affect this parameter.
Notes:
Readings are measured at rated current after temperature stabilizes
The F1250Z8 meets the requirements of UL 248-14. However, board layout, board trace widths, and ambient
temperature values can cause higher than expected rises in temperature. During UL testing, the typical
recorded heat rise for the F1250Z8 at 2.2 A was 120 C.
