CG5 and SL0902A Series

Description

Littelfuse Broadband Optimized™ SL0902A Series offers

high surge ratings in a miniature package. Special design

features provide high levels of protection against fast

rising transients in the 100V/μs to 1kV/μs range usually

caused by lightning disturbances. Low insertion loss is

perfectly suited to broadband equipment applications.

The capacitance does not vary with voltage, and will

not cause operational problems with ADSL2+, where

capacitance variation across Tip and Ring is undesirable.

These devices are extremely robust and are able to

divert a 2500A pulse without destruction. For AC

Power Cross of long duration, overcurrent protection is

recommended.

Littelfuse CG5 MS mini surge arresters are speciﬁcally

designed for protection of electrical and communication

equipment against over voltage transients in surface

mount assembly applications. This series offers the most

cutting edge protection using non-radioactive elements.

Features

• RoHS compliant and

Lead-free

• GHz working frequency

• Excellent stability on

multiple pulse duty cycle

• Excellent response to

fast rising transients.

• Ultra Low Insertion Loss

• 5KA surge capability

tested with 8/20μS

pulse as deﬁned by IEC

61000-4-5, 2nd edition

• Ultra small devices

offered in a variety of

mounting lead forms

• Non-Radioactive

• Low capacitance (<1pF)

• Voltage Ranges 90V to

600V

• UL Recognized

• Conforms to ITU-T K12,

IEC 61000-4-5, 2nd

edition
