Bell Pin (TM) Surface Mount Feedthrus Now Reach 25 GHz

HAMPSTEAD, NH-February 27, 2008 - Thunderline-Z, a designer and manufacturer of soldered and direct sealed hermetic packages and RF, DC, and capacitive feedthrus, is pleased to announce an expansion to its line of innovative Bell Pin(TM) surface-mount feedthru products.

Bell Pins provide a low-cost and higher-frequency alternative to glass-to-metal feedthrus, and are constructed with a gold-plated Kovar base and a center conductor fired in place with low-loss corning glass.

The latest development in the Bell Pin line is a smaller-diameter pin option of .009". It is designed for frequency operation through 25 GHz.

"The engineering of a smaller pin in our new Bell Pin is the key enabler in giving our customers use of this feedthru style at the increasingly popular J and K band frequency ranges," says Debra Breed, general manager at Thunderline-Z.

Bell Pins work with lightweight aluminum or brass housings, easily mounting to the bottom of the package to create true surface mountable parts with increased performance. They deliver 50 ohm performance, and are part of a solution to reduce cost and weight in microwave packages.
