Ohmicone Silicone-Ceramic Conformal

Axial Terminal Wirewound

1% and 5% Tolerance Standard

40 Series

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.
