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 155 °C is not exceeded.
• The specification of this product is based on a test board, providing a thermal resistance of approximately 85 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.
• Zero ohm jumper are marked with one centered black band.

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.
• The specified dissipation of 1 W relies on special support from the printed-circuit board in order to achieve the required heat flow. Specification
of a particular conductor size is not feasible since its thermal performance depends on a variety of influences from the actual PCB design and
from the application environment.
