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.
