JERSEY CITY, N.J.--(BUSINESS WIRE)--March 1, 2001

A three-module family of Home Phoneline Networking Alliance (HomePNA) bandpass filters has recently been announced by Bel Fuse Inc., a premier developer of LAN and Telecom networking components.

Specifically designed to meet all electrical standards of Broadcom's iLine10 (TM) (BCM4210 and BCM4100) series of home networking chipsets, the new SMT S556-5000-14, -15 and S556-5000-30 components include a transformer, bandpass filter and common mode choke to ensure high-speed data integrity on existing, non-dedicated phone lines.

All three Bel devices comply with the 10 Mbps standard for HomePNA 2.0 compliance, and are UL/IEC950 approved for supplementary isolation.

Essential for use with network interface cards and stand alone systems employing Broadcom's iLine10TM ICs, Bel's modules have broad application in small office/home office (SOHO) environments and networking applications. In addition to NICs, routers, hubs and gateways, these devices are used in cable modems, set top boxes, home appliances laptops, and personal digital assistants (PDAs).

Key specifications of the filter modules include insertion loss of -1.0 dB, average return loss better than -12.0 dB, and attenuation of -60 dB at 1.1 MHz, -35 at 22 MHz and -60 dB at 54 MHz. They moreover feature minimum interwinding breakdown voltage of 1500 Vrms and high common to differential mode rejection (-40 dB). Turns ratio of 0.667:1 for transmit, and 2:1 for receive, match Broadcom chipsets' specifications.

While both the S556-5000-14 and -15 are provided in an industry standard 20-pin configuration, the S556-5000-15 is designed with a 2 kVDC capacitor. To satisfy the low-profile requirements of PCI and mini PCI cards necessary for portable and hand-held devices, Bel's S556-5000-30 PCMCIA package boasts a height of only 0.092".

In quantities of 10K, prices for each module are: $2.00 for the S556-5000-14; $2.25 for the S556-5000-15; $2.35 for the S556-5000-30. Delivery is stock to 6 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.
