MARKING

For 0603 above size, each resistor is marked with a four-digit for 1% tolerance and three-digit for 5%

tolerance on the protective coating to designate the nominal resistance value.

For 0603, each resistor is marked with a three-digit!

For 0402, no marking !

For Jumper, 2512/2010 defines 0000, 1206/0805/0603 defines 000.

Example:

102 = 1k

16R0 = 16

FUNCTIONAL DESCRIPTION

Product characterization

Standard values of nominal resistance are taken from the E96 & E24 series for resistors with a tolerance of

5% & 1%. The values of the E24/E96 series are in accordance with “IEC publication 60063”.

Derating curve

The power that the resistor can dissipate depends on the operating temperature; see Fig.2
