SAN JOSE, Calif.—(BUSINESS WIRE)—Jan. 12, 2005— WJ Communications, Inc. (Nasdaq: WJCI), a leading designer and supplier of RF semiconductors and multi-chip modules, today announced that all products in the popular SOT-89 package are now available in the environmentally-friendly lead-free/green/ RoHS-compliant packages. The lead-free and green part number will end in "G" to signify compliance with Industry Standards. The company now offers over 80% of its available devices in lead-free and green packaging. WJ datasheets have been updated to reflect the new part number for each device.

"Demand for such lead-free products is especially high in Europe and Japan, since the restriction of hazardous substances directive has been initiated. WJ plans to complete the conversion to lead-free of its entire product portfolio by Q2, 2005," said Ron Buswell, senior vice president of marketing and product line for WJ Communications. "WJ has successfully achieved lead-free with its QFN 6x6mm and SOT-89 packages. This is just one of the many environmental activities that represent WJ's company-wide commitment to environmental protection, while continuously providing high performance and low-cost RF semiconductors for the wireless infrastructure market."

All WJ lead-free products are also RoHS compliant; green products are lead-free, RoHS compliant, and have limitations on other specific chemicals as well as being backward compatible with lead-based SMT processing. All of WJ's lead-free products will meet the requirements of the European Union to minimize hazardous substances throughout the electronics industry.

The SOT-89 package has been lead-free/Green/RoHS qualified to a maximum reflow profile temperature of 260 degrees C and the MSL rating at this reflow profile is level 3. The lead finish is Nickel Palladium and Gold (NiPdAu).


All devices in the lead-free SOT-89 packaging are available for immediate shipment. Sample quantities are available now and can be requested directly from the WJ web site ( www.wj.com).
