MARKING
Series, style, ohmic value (in Ω ), tolerance (in %),
manufacturing date, Vishay Sfernice trademark.
POWER RATING
The temperature of the case should be maintained within the
limits specified in the following figure.
To optimize the thermal conduction, contacting surfaces
should be coated with silicone grease or thermal film, and
heatsink mounting screws tightened to 2 Nm.
