IRC Advanced Film Division
The PAT0510 chip attenuator is designed for surface mount installa-
tion on printed circuit boards. These attenuators are designed with wrap-
around terminals for solder attachment. Typical applications include mobile electronics where space savings is
a critical design factor.
