DESCRIPTION
The attenuators are constructed in a high grade ceramic body (aluminum oxide).
Internal circuit is applied to the top surface of the substrate. One protective coat is
printed upon the internal circuit & two external end terminations are added.
For ease of soldering the outer layer is coated by a lead/tin alloy.
