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.
