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.  
They offer the durability of a lead free conformal vitreous  
enamel coating and are ideal for computer, communications and  
industrial applications in which cost, quality, and reliability are  
key considerations.
