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. FeatureS Units with 1% and 5% tolerances are identical in • Economical construction and electrical specifications. Durable • Applications include commercial, industrial and but economical 40 Series resistors exceed industry communications equipment requirements for quality. • Stability under high temperature conditions • All-welded construction • RoHS compliant; add “E” suffix to part number to specify.
