Notes

*

This datasheet provides information about parts that are RoHS-compliant and/or parts that are non-RoHS-compliant. For example, parts

with lead (Pb) terminations are not RoHS-compliant. Please see the information/tables in this datasheet for details.

Notes

• Part marking: Value; tolerance: Due to resistor size limitations some resistors will be marked with only the resistance value.

 derate linearly to 80 % rated power at 0.5 .
