Resistance Values:
Resistance values in ohms are identified by four characters consisting of three digits and a letter. The letter is used simultaneously as a decimal point, multiplier, and a resistance tolerance designator in accordance with the above table. All of the digits preceding and following the letter represent significant figures. The following table shows examples for the 1.0% tolerance designator.
