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.
Note
• Wirewound CPR resistors can reliably function as a fuse and as a resistor. Such components involve compromise between fusing and
resistive functions; therefore, each design should be tailored to the application to ensure optimum performance. Contact factory by using
the e-mail address at the bottom of this page for design assistance.
