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.

153

2372

153 = 15000Ω = 15KΩ

• ±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.

Below 10Ω: 6R8 = 6.8Ω

2372 = 23700Ω = 23.7KΩ

Below 10Ω : 3R24 = 3.24Ω

Standard E-24 and not belong to E-96 series values (≤±1%) of 0603 size: the marking is the same as 5% tolerance but marking as underline.
