RAS-20680JKNM Preview

On a high grade ceramic body(aiuminium oxide) a metal glaze layer is screened.Depending on the composition
of the metal glaze different resistance values can be obtained. On both ends a contact is made in such a way
that optimum solderability is guaranteed. This is achieved by applying three layers. The resistive layer is 
covered with a protective coat.
Features
1. Miniature size can compact P.C. Board.
2. 8mm tape carrier packaging available for automatic surface mounting.
3. Excellent mechanical strength and electrical stability.
4. Reduce assembly costs.
Options
● Option 'AS'
Anti‐Surfurate, suitable for Automative industry, meet AEC ‐ Q 200 test 
Test condition  H
