Metal Film Resistors, Power, Surface Mount
Note
* 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.
FEATURES
• Molded encapsulation
• Wraparound compliant terminations eliminate
risk of solder fillet cracking
• Solderable terminations
• Excellent stability at different environmental
conditions
• High power ratings (up to 2 W)
• AEC-Q200 qualified available ⁽¹⁾
• Material categorization:
for definitions of compliance please see
