SCOPE

ORDERING INFORMATION - GLOBAL PART NUMBER

This specification describes

YC248 series chip resistor arrays

with lead-free terminations made

by thick film process.

Both part numbers are identified by the series, size, tolerance, packing

type, temperature coefficient, taping reel and resistance value.

CONSTRUCTION

OUTLINES

The resistor is constructed on top

of a high-grade ceramic body.

Internal metal electrodes are added

on each end to make the contacts to

the thick film resistive element. The

composition of the resistive element

is a noble metal imbedded into a

glass and covered by a second glass

to prevent environment influences.

The resistor is laser trimmed to the

rated resistance value. The resistor

is covered with a protective epoxy

overcoat

resistive layer
