40 Series Ohmicone Silicone-Ceramic Conformal Axial Terminal Wirewound 1% and 5% Tolerance Standard (R) 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 electrical 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.
