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- F e at u r e S cal and electronic applications. 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 industr y communications equipment requirements for quality. Stability under high temperature conditions All-welded construction RoHS compliant add E suffix to part number to specify.
