DIMENSIONS

Note

• Color code marking is applied according to IEC 60062 (1) in four, five, or six bands. Each color band appears as a single solid line, voids are

permissible if at least 2/3 of the band is visible from each radial angle of view. The last color band represents the TCR for resistors with TCR

≤ 50 ppm/K and nominal tolerance ≤ 1 %. In case of transparent body coating lacquer, an interrupted band between the 4th and 5th full

band indicates the TCR: in yellow color for ± 25 ppm/K and in orange color for ± 15 ppm/K

PATTERN STYLES FOR MELF RESISTORS

Notes

• The given solder pad dimensions reflect the considerations for board design and assembly as outlined e.g. in standards IEC 61188-5-x (1),

or in publication IPC-7351

(1) The quoted IEC standards are also released as EN standards with the same number and identical contents
