Thick Film Chip Resistors
Marking on the Resistors Body:
UniOhm
• For 0402 size, no marking on the body due to the small size of the resistor. • ±5% tolerance product. 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
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
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.
