Wrap-around terminations
(3 faces)
Construction
Conductors, resistive element, glass inner protection and epoxy outer protection are applied to a 96% alumina substrate. The chips are
supplied with wrap-around terminations suitable for soldering. The terminations have an electroplated nickel barrier and 100% matt tin
finish.
Marking
Sizes larger than 0603 are individually marked with 4 digits. The first three digits are the significant figures and the fourth defines the
number of added zeros.
Size 0603, E24 values are marked with 3 digits. The first two digits are the significant figures and the third defines the number of added
zeros.
Size 0603, E96 values are marked with a standard 3 digit EIA96 code.
Size 0402 has no marking.
The body protection and marking are resistant to all normal cleaning solvents suitable for printed circuits.
