Vishay Dale
Metal Film Resistors, Axial, Special Purpose, Fusible, Flameproof
FEATURES
• Special filming and coating processes
• Fusible - circuit protection in case of other
component failure
Available
• Flameproof - meets EIA RS-325, will not flame
when overloaded
• Tape and reel packaging is standard
Available
• Material categorization: for definitions of
compliance please see www.vishay.com/doc?99912
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.
