20J10R Ohmite

20 Series Vitreous Enamel Conformal Axial Terminal Wirewound, 5% Tolerance Std. FeatureS Rugged vitreous enamel coating withstands high The 20 Series axial terminal resistors are both humidity and temperature cycling. durable and economical. They have all the electrical Durable construction, recommended for industrial attributes of the more expensive 90 Series resistors, applications where reliability is paramount. including all-welded construction. They offer the durability of a lead free conformal All-welded construction. vitreous enamel coating and are ideal for computer, Flame resistant lead free vitreous enamel coating. communications and industrial applications in which RoHS compliant Add E suffix to part number to cost, quality, and reliability are key considerations. specify.
