Wrap-around terminations
(3 faces)
Construction
The chips have a high alumina substrate (96% minimum) with a
ruthenium oxide resistance element and silver palladium, nickel and tin
plated terminations. A glazed protection coat is applied to the resistive
element (see fig1)
Terminations
Solderability
Strength
The terminations meet the requirements of IEC 115-1, Clause 4.17.3.2
The terminations meet requirements of IEC 68.2.21
