TeleLink
Fuse
The
TeleLink
Surface Mount (SM) surge resistant fuse offers circuit protection without
requiring a series resistor. When used in conjunction with the
SIDACtor
Transient Voltage
Suppressor (TVS), the
TeleLink
SM fuse and the
SIDACtor
TVS provide a complete
regulatory-compliant solution for standards such as GR 1089, TIA-968 (formerly known as
FCC Part 68), UL 60950, and ITU K.20 and K.21. No series resistor is required for the
F1250T and F1251T to comply with these standards.
Contact factory for enhanced K.20 and K.21 details.
* 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.
I
2
t is a non-repetitive RMS surge current rating for a period of 16.7 ms.
Notes:
Typical inductance 4 μH up to 500 MHz.
Resistance changes 0.5% for every °C.
Resistance is measured at 10% rated current.
