Product specification

Standard chip resistors

sizes 1206, 0805, 0603 and 0402

RC01/11/21/31

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.

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

For values up to 976

Ω the R is used

as a decimal point. For values of 1 k

Ω

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.
