![](/uploads/spec-pics/20145678/TCP-1.25A-500MA-2A-ROHS.jpg)
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 STMicroelectronics Trisil™ Transient Surge Arrestor (list of part numbers below)

Special Investigation
The TCP1.25A is designed to provide overcurrent protection for telecom SLIC, xDSL modem, and set-top box applications regardless of the overvoltage device selected. To provide an easier specification experience, Cooper Bussmann and STMicroelectronics have joined together to provide a special test report confirming the coordination between the TCP1.25A and SMP100MC-270 devices.
