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 coating and printed with the
resistance value. Finally, external end
terminations are added. For ease of
soldering the outer layer of these end
terminations is a lead-tin alloy.

FUNCTIONAL DESCRIPTION
Product characterization
Standard values of nominal
resistance are taken from the
E24 or E96 series for resistors
with a tolerance of
±5%
or
±1%.
The values of the E24/E96 series
are in accordance with
“IEC publication 60063”.

Marking
All resistors within the E24 series are
marked with a 3-digit code and a
4-digit code for resistors of the
E96 series, on the protective coat to
designate the nominal resistance
value.

DIGIT MARKING
For values up to 91
Ω
the R is used as
a decimal point. For values of 100
Ω
or greater the first 2 digits apply to the
resistance value and the third
indicates the number of zeros to
follow.

TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the schedule of
“IEC publication 60 115-8”,
category

(rated temperature
range:
Lower Category Temperature, Upper Category Temperature;
damp heat, long term,
56
days). The testing also covers the requirements
specified by EIA and EIAJ.
The tests are carried out in accordance with IEC publication 60 068,
“Recommended basic climatic and mechanical robustness testing
procedure for electronic components”
and under standard atmospheric
conditions according to
“IEC 60068-1”,
subclause 5.3.

In Table 4 the tests and requirements are listed with reference to the
relevant clauses of
“IEC publications 60 115-8 and 60068”
; a short
description of the test procedure is also given.

necessary for our method of specifying.
All soldering tests are performed with mildly activated flux.
