Bel's LAN Magnetics Support IP Phone & Switch Applications Without External Power.

Business Editors

JERSEY CITY, N.J.--(BUSINESS WIRE)--June 12, 2000

A three-module family of 10/100 Base-TX dual transformers has recently been announced by Bel Fuse Inc., a premier developer of magnetic components for high-speed transmission and networking.

These surface mount devices were developed to satisfy the burgeoning Voice over Internet Protocol (VoIP) marketplace, and are optimized for Internet Protocol (IP) phone and switch applications. As they support up to 300 mA onto standard LAN cabling, the need for external power is eliminated. They are further designed to interface with, and maximize the performance of, most major IC manufacturers' transceivers, and meet IEEE 802.3 standards.

All three dual port interface transformer modules feature an operating temperature range of 0 degrees C to 70 degrees C, isolation voltage of 1500 Vrms and a primary inductance of 350 microhenry. Specifically engineered for IP phones, the S558-5500-02 boasts a space-saving 0.542" L x 0.480" W x 0.250" H footprint, while the S558-5500-04 measures 0.522" L x 0.600" W x 0.250" H. Bel's S558-5500-12, to be specified for switch applications, affords maximum EMI noise suppression while promoting both power feed and return on standard LAN cabling. Its dimensions are 0.522" L x 0.600" W x 0.250" H.

To facilitate EOEM's throughput and profitability objectives, components' surface mount packages are compatible with standard pick-and-place assembly equipment and vapor and IR reflow soldering processes.

They are available in tube(s) and tape and reel packaging with prices, in quantities of 10K, of $2.27 each for modules S558-5500-02, -04 and $2.59 each for the S558-5500-12. Delivery is from stock to six weeks.

An industry leader in the design, engineering and manufacturing of magnetics, fuses, delay lines and thick film hybrids, Bel produces quality electronic components for the global market. Bel's products are widely specified for use in telecommunication and data communication (LAN/WAN) networks, computer and power supply applications, audio/visual equipment, consumer electronics, and home appliances worldwide. Testifying to Bel's commitment to quality, all components are manufactured in ISO 9000 certified facilities in Hong Kong, Macau and China.
