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.
