MMU 0102, MMA 0204 and MMB 0207 professional thin film
MELF resistors are the perfect choice for most fields of
modern professional electronics where reliability and stability
is of major concern. The typical applications in the fields of
automotive, telecommunication and medical equipment
reflect the outstanding level of proven reliability.

Note: These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over
operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime.
1)
The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heatflow support of the
printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a
high level of ambient temperature or of power dissipation may raise the temperature of the solder joint, hence special solder alloys or board
materials may be required to maintain the reliability of the assembly.
2)
Specified power rating requires dedicated heat-sink pads.
3)
Film temperatures above the specified range may be permissible, e.g. 175 °C. Please contact the factory for details.
1. Products can be ordered using either the PRODUCT DESCRIPTION or the 12NC.
2. The PART NUMBER is shown to facilitate the introduction of the unified part numbering system. Currently, this PART NUMBER is applicable
in the Americas and in Asia/Pacific only.
3. Please refer to table PACKAGING, see below.
4. A temperature coefficient 100 ppm/K is marked - 00.
Color code marking is applied according to IEC 60062* in four bands (E24 series) or five bands (E96 or E192 series). Each colour 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 colour band for tolerance
is approximately 50 % wider than the other bands. An interrupted yellow band between the 4th and 5th full band indicates the temperature
coefficient of 25 ppm/K.
