IAX Series Surface Mount
Thick Film Attenuator
IAX Series surface mount thick film attenuators are compact,
high performance devices especially suited to RF and microwave
applications. For bondable terminations, other substrate thicknesses
or other sizes and power levels, consult the factory.
Other case sizes and values are available upon request1 and
are often delivered in half the lead times of most competitors.
