EMC Technology’s attenuators are
available in a low power chip package.
The power ratings range from 0.1 to 2
watts. The attenuation values range
from 1 dB to 20 dB. The terminals of
EMC chip attenuators are made with
thick film base material that is nickel
plated and solder coated. The resistive
element is thin film offering superior
electrical performance. The TS04 series
uses thick film resistor elements. The
devices are available for shipping in
tray or tape and reel packaging.
