The marking is 3 digits, the first 2 digits are the significant figures of the resistance and the 3rd digit denotes number of zeros following: . 153 %HORZVKRZQDVWKLV5 6R8 • ±1% tolerance of 0805,1206 sizes. The marking is 4 digits, the first 3 digits are the significant figures of the Resistance and the 4th digit denotes number of zeros following: 2372 . %HORZVKRZQDVWKLV5 3R24 • Standard E-96 series values (±1% tolerance) of 0603 size. Due to the small size of the resistor’s body, 3 digits marking will be used to indicate the accurate resistance value by using the following Multiplier & Resistance Code.
