40 Series
Ohmicone® Silicone-Ceramic Conformal
Axial Terminal Wirewound
1% and 5% Tolerance Standard
Ohmite 40 Series resistors are the most economical
conformal silicone-ceramic coated resistors offered.
These all-welded units are characterized by their low
temperature coefficients and resistance to thermal
shock, making them ideal for a wide range of electri-
cal and electronic applications.
Units with 1% and 5% tolerances are identical in
construction and electrical specifications. Durable
but economical 40 Series resistors exceed industry
requirements for quality.
F e at u r e s
• Economical
• Applications include commercial, industrial and
communications equipment
• Stability under high temperature conditions
• All-welded construction
• RoHS compliant; add “E” suffix to part number to
specify.
