Vishay Dale
Metal Film Resistors, Special Purpose, Fusible, Flameproof
FEATURES
• Special filming and coating processes
• Fusible - circuit protection in case of other
Available
component failure
• 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.

• Fusing time graphs represent an average for the resistance value range. Low resistance parts require higher power to fuse than high
resistance parts. It is recommended that values less than 200  be evaluated for specific applications.
