TeleLink® Series - Surface Mount Surge Resistant Fuse

Brand: Littelfuse, Inc

Does not require a series resistor.

Using a TeleLink® surface mount fuse in conjunction with a SIDACtor® transient voltage suppressor provides a complete regulatory-compliant solution for standards such as GR 1089, TIA/EIA-IS-968, UL 60950, and ITU K.20 and K.21.

Designed to carry 100 percent of its rated current for four hours and 250 percent 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.

Note: Obsolete: 2015 -04-01 Replaced By 461 Series
Features
