WT04X Chip Resistor Network 10P8R
Ϯ
Description
The resistor array is constructed in a high grade ceramic body (aluminum oxide).
Internal metal electrodes are added at each end and connected by a resistive
paste that is applied to the top surface of the substrate. The composition of the
paste is adjusted to give the approximate resistance required and the value is
trimmed to within tolerance by laser cutting of this resistive layer.
The resistive layer is covered with a protective coat. Finally, the two external end
terminations are added. For ease of soldering the outer layer of these end
termination is Tin (Pb free) solder alloy.
