Metal Film Resistors, 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.

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.
