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).
• TCP1.25A tested and confirmed compatible with
