BS1852 Resistor Coding

<^< Examples: Resistor Colour Code Test | Course Index | Examples: BS1852 Resistor Coding >^>(:nl:)

Some types of resistor have markings based on a system of coding defined in BS 1852. This system involves marking the position of the decimal point with a letter to indicate the multiplier concerned. A further letter is then appended to indicate the tolerance as shown in the table below.

F±1%
G±2%
J±5%
K±10%
