Product specification

Standard chip resistors

sizes 1206, 0805, 0603 and 0402

RC01/11/21/31

FEATURES

• Low assembly costs

• High component and equipment

reliability

• Excellent performance at high

frequency, especially the RC31

• Complete standard SMD family.

APPLICATIONS

• All general purpose applications.

DESCRIPTION

The resistors are constructed on a

high grade ceramic body (aluminium

oxide). Internal metal electrodes are

added at each end and connected by

a resistive paste which 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 and printed with the

resistance value. Finally, the two

external end terminations are added.

For ease of soldering the outer

layer of these end terminations is a

lead/tin alloy.
