Wrap-around terminations have an electroplated nickel barrier and matt tin plating Wraparound Termination this ensures excellent leach resistance properties Bridge Electrode and solderability. Top Electrode Bottom Electrode Marking 5% parts are marked with 3 digits. The first two digits are significant figures and the third digit is the number of zeros to follow. The letter R represents a decimal point. 1% parts have four digits, the first three digits are significant figures and the fourth digit is the number of zeros to follow. The letter R represents a decimal point. Solvent Resistance The body protection is resistant to all normal industrial cleaning solvents suitable for printed circuits.
