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.
