Thin Film Surface Mount
Temperature Variable
Chip Attenuator
The
ims
AV-0805 thin film surface mount temperature variable chip attenuator is
ideal for applications requiring precise attenuation with integrated temperature
compensation in a small form factor. This attenuator is designed in the PI configura-
tion. Thin film technology insures a low noise, precise attenuator at a very affordable
price. Nine different temperature characteristics are available. The wraparound
terminals include a nickel barrier layer which affords excellent leach resistance and
mechanical integrity. This chip attenuator has the following features:
