20 Series
Vitreous Enamel Conformal Axial
Terminal Wirewound, 5% Tolerance Std.
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.
F e at u r e S
• Rugged vitreous enamel coating withstands high
humidity and temperature cycling.
• Durable construction, recommended for industrial
applications where reliability is paramount.
• All-welded construction.
• Flame resistant lead free vitreous enamel coating.
• RoHS compliant; Add “E” suffix to part number to
specify.
