Thick Film Chip Resistors
Marking on the Resistors Body
• For 01005, 0201, 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 of the resistance and the
3rd digit denotes number of zeros following.
• 0805, 1206, 1210, 2010, 2512 ≤±1%: the marking is 4 digits, the first 3 digits are the significant of the
resistance and the 4th digit denotes number of zeros following.
• Standard E-96 series values of 0603 ≤±1%: 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.
