TCP Series

TCP1.25A,Telecom Circuit Protector

Description

• The first and most reliable surface mount telecom circuit

protector designed to protect against power cross faults

and comply with all surge requirements.

• Allows compliance with telecom regulatory standards

including Bellcore GR 1089, UL 1950/60950, and FCC part

68. Application circuit testing is recommended.

• Eliminates the need for a current limiting resistor.

• Protects against overcurrent conditions found in telecom

Subscriber Line Interface Cards (SLICs), xDSL Modem

Applications, Set-Top Boxes, and Consumer Premises

Equipment (CPE).

Dimensions
