Fuse Products Circuit Protection SIP Modules CPSIP1002 Features • Space-saving, vertical, through hole configuration • Tip and Ring protection schemes consist of voltage protectors (SIDACtor®, TISP®, thyristor, etc.) in combination with Bel’s 1.25A SMP fuses • Customized designs provide solutions for a wide variety of voltages • Two and four channel packaging on ceramic substrate • Standard designs also available • Fully integrated design helps accelerate time to market for telecommunication devices Applications • Digital Subscriber Line (DSL) • Analog Line Cards • T1/E1Interface Circuits • Digital Line Cards Bel’s value-added modules provide circuit protection in a space-saving, vertical-mount, SIP configuration. Designed for use in a variety of telecom applications, the modules incorporate voltage protectors with Bel’s 1.25A, surface mount SMP fuses. These fuses comply with the Power Cross test requirements UL 1950/60950 and Bellcore/Telcordia GR-1089 for Tip and Ring protection and withstand lightning surges specified in FCC 47 Part 68. These Bel modules are ideal for use where high density chipsets are being implemented as they provide an integrated protection scheme to support the greater number of protection components required. Packaged on ceramic substrate via Bel’s high volume manufacturing techniques, these circuit protection modules utilize minimal board space, while maximizing manufacturing throughput. The design of these modules can be customized according to the requirements of board design and voltage protection, offering the flexibility to accommodate a wide range of voltage protection schemes. ©2002 Bel Fuse Inc.

Power Cross - Equipment certified to GR-1089 and UL/IEC 60950 must also comply with tests simulating contact of a power line with a telephone line. In these 600 volt tests, protection must be provided to prevent shock and fire hazard, as well as maintain integrity of the overvoltage protector. Bel’s SMP fuses provide stand-alone power cross protection and are rated to withstand the various lightning surge conditions that are applied to telecommunications equipment. Most designs typically employ discrete fuses and overvoltage protectors, usually in surface mount packages, on the main circuit board. As higher density chipsets are introduced, the number of Tip and Ring channels per board has increased dramatically, requiring a greater number of components to be placed. Bel’s integrated SIP protection modules combine fuses, overvoltage protectors and resistor networks in space-saving, vertical mount configurations, freeing up valuable lateral board space. ©2002 Bel Fuse Inc.
