The leads are moulded into the resistor. Finally these are coated and band marked. Marking CC series resistors are colour coded. Resistors with 20% tolerance have three bands indicating value, and resistors with 10% tolerance have four bands indicating value and tolerance in accordance with IEC62. Solvent Resistance The body protection and marking are resistant to all normal industrial cleaning solvents suitable for printed circuits.
