Notes
• SMM0204 EN803 E0 and OMM0204 EN803 E0 respectively are available versions with IECQ-CECC approval to EN 140401-803, version A,
with nominal failure rate level E0.
• The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support of the
printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature of 155 °C is not exceeded.

Notes
• The upper temperature limit of 125 °C reflects the prescriptions of the detail specification EN 140401-803. However, the products may be
operated up 155 °C, if the tradeoff through decreased drift stability is acceptable to the specific application.
• The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support of the
printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature of 125 °C or 155 °C respectively
is not exceeded.
• The specification of this product is based on a test board according to EN 140400, providing a thermal resistance of approximately 220 K/W.
• 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.
• The IECQ-CECC approved product versions SMM0204 EN803 E0 and OMM0204 EN803 E0 respectively feature a quality factor
Q
= 3 for
the purpose of system MTBF calculations, compared with
Q
= 10 for the standard versions.

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
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.
• 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.

• 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.
