The PFC A1206 chip attenuator is a surface mount attenuator available

in nominal values of 50Ω and 75Ω to meet the needs of both communication

and video designs. Packaged in a rugged 1206 ceramic chip package, the PFC-A1206 lends itself to RF and

microwave applications up to 6GHz.

The tantalum nitride thin film element is well known for its ruggedness in the most severe outdoor environments

and its stability over temperature and time. For your most demanding environmental attenuator applications,

specify the IRC PFC-A1206 chip attenuator.

Note*: Typical from 0 to 6GHz.
