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.
QUICK REFERENCE DATA

MECHANICAL DATA
Mass per 100 units
Marking
Each resistor, except RC31, is
marked with a three digit code
(occasionally four digit) on the
protective coating to designate the
nominal resistance value.
3-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 are
significant, the third indicates the
number of zeros to follow.
Example
4-DIGIT MARKING
For values up to 976 Ω the R is used
as a decimal point. For values of 1 kΩ
or greater the first 3 digits are
significant, the fourth indicates the
number of zeros to follow.
Example
The packaging is also marked and
includes resistance value, tolerance,
TC value, catalogue number,
quantity, production period, batch
number and source code.

TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the schedule of
“IEC publication 115-8”
, category LCT/UCT/56 (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 68,
“Recommended basic climatic and mechanical robustness testing
procedure for electronic components”
and under standard atmospheric
conditions according to
“IEC 68-1”
, subclause 5.3.
Unless otherwise specified the following values apply:
Temperature: 15 °Cto35°C
Relative humidity: 45% to 75%
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
In Table 4 the tests and requirements are listed with reference to the
relevant clauses of
“IEC publications 115-8 and 68”
; a short description of
the test procedure is also given. In some instances deviations from the
IEC recommendations were necessary for our method of specifying.
All soldering tests are performed with mildly activated flux.
