Notes
• 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 is not exceeded.
• The specification of this product is based on a test board according to EN 140400, providing a thermal resistance of approximately 275 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.

Notes
• Color code marking is applied according to IEC 60062
(1)
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. An interrupted band between the 4
th
and 5
th
full band indicates the temperature coefficient (yellow = TC25, orange = TC15).
• Zero ohm jumper are marked with one centered black band.

applications.
