BS 1852

The British standard BS 1852 and its replacement, BS EN 60062, comprises a colour code for fixed resistors; letter and digit code for resistance (R for ohms, K for kilohms and M for megohms) and capacitance values.

Codes

Letter code for resistance and capacitance tolerances and a date code for capacitors and resistors:

coding:

Steps to find out the resistance or capacitance values:

1st 2 letters gives the power dissipation capacity.

next 3 digits gives the resistance value.

1st 2 digits are the significant values
3rd digit is the multiplier.

1st 2 digits are the significant values

3rd digit is the multiplier.

final digit gives the tolerance.

Examples

If a resistor is coded :

EB1041: power dissipation capacity = 1/2 watts, resistance value = 10×10^4±10% = between 9×10^4 ohms and 11×10^4 ohms.

CB3932: power dissipation capacity = 1/4 watts, resistance value = 39×10^3±20% = between 46.8×10^3 ohms and 31.2×10^3 ohms.
