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.
