DIMENSIONS

Notes

• Color code marking is applied according to IEC 60062 in four bands for 5 % tolerance, or in five bands. Each color band appears as a single

approximately 50 % wider than the other bands.

• The color of the body coating is light green for jumpers and for a temperature coefficient of ± 50 ppm/K or of ± 100 ppm/K, pink for ± 25 ppm/K,

or violet for ± 15 ppm/K.

• Zero ohm jumper are marked with one centered black band.

PATTERN STYLES FOR MELF RESISTORS

Note

• The given solder pad dimensions reflect the considerations for board design and assembly as outlined e.g. in standards IEC 61188-5-x, or in

publication IPC-7351. They do not guarantee any supposed thermal properties, however, they will be found adequate for most general

applications.
