20 Series
Vitreous Enamel Conformal Axial Terminal
Wirewound, 5% Tolerance Standard
The 20 Series axial terminal resistors are both durable and
economical. They have all the electrical attributes of the more
expensive 90 Series resistors, including all-welded construction.
enamel coating and are ideal for computer, communications and
industrial applications in which cost, quality, and reliability are
key considerations.
