Ohmite MX2K10RE-R58 Metal oxide resistors 5% tolerance rohs compliant Datasheet

This product has been
MX Series
DISCONTINUED
The MX Series Metal Oxide
Resistors provide stable performance at low cost across a
wide resistance range. They
can be used as a substitute for
wirewounds when short time
overloads are limited to 2.5
times rated power, and when
higher TCRs can be tolerated.
