The MX Series Metal Oxide
Resistors provide stable per-
formance 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.
FEATURES

• Flame retardant coating
• Wide resistance range
• Quantity per reel:
MX1 = 2500
MX2 = 2500
MX3 = 1000
MX5 = 500 (bulk only)
