Notes
(1)
The quoted IEC standards are also released as EN standards with the same number and identical contents
(2)
The pulse load stability of professional MELF resistors applies for precision resistors also. However, severe pulse loads are likely to
jeopardize precision stability requirements

DIMENSIONS
Note
Color code marking is applied according to IEC 60062
(1)
in five bands (E96 or E192 series). 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 for tolerance is approximately
50 % wider than the other bands. An interrupted band between the 4
th
and 5
th
full band indicates the temperature coefficient (yellow = TC25,
orange = TC15)
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

or in publication IPC-7351

HISTORICAL 12NC INFORMATION
The resistors had a 12-digit numeric code starting with
2312.
The subsequent 4 digits indicated the resistor type,
specification and packaging; see the 12NC table.
The remaining 4 digits indicated the resistance value:
- The first 3 digits indicated the resistance value.
- The last digit indicated the resistance decade in
accordance with the 12NC Indicating Resistance
Decade table.
Last Digit of 12NC Indicating Resistance Decade
Historical 12NC
The 12NC of a MMU 0102 resistor, value 47 k. and TCR 25
with ± 0.25 % tolerance, supplied in blister tape of 3000
units per reel is: 2312 166 64703.
