Thin Film Surface Mount Chip
Attenuator
The
ims
A-0805 thin film surface mount chip attenuator is ideal for
applications requiring precision attenuation in a small form factor package.
The attenuator is provided in the π configuration. Thin film technology
insures a low noise, precise attenuator at a very affordable price. The
wraparound terminations include a nickel barrier layer which affords
excellent solderability and mechanical integrity. This chip attenuator has
the following features:
