Marking on the Resistors Body
•
•
For 0402 size, no marking on the body due to the small size of resistor.
±5% tolerance product. (Including resistance values less than 1Ω; both 1% and 5%) The marking is 3 digits, the first 2 digits are
the significant figures of the resistance and the 3rd digit denotes number of zeros.
