You can help by adding to it.
Additional zeros imply tighter tolerance, for example 15M0. The standards also define a color 60062 for fixed resistors. However, the letter E is conflictive with the similar looking but incompatible E notation in engineering, iec 60062 it iec 60062 therefore cause considerable confusion as well. It may iec 60062 cause confusion in some contexts. Similar, the standard prescribes the following lowercase letters for capacitances to be iec 60062 instead of the decimal point: The letters G and T weren’t part of the first issue of the standard, which pre-dates the introduction of the SI system hence the name “RKM code”iec 60062 were added after the adoption of the corresponding SI prefixes.
The significantly updated IEC The notation also avoids using a decimal separator and replaces it by a letter associated with the prefix symbol for the particular value.

iec 60062 This method avoids overlooking the decimal separatorwhich may not be rendered iec 60062 on components or when duplicating documents. The code letters are 600662 related to the iec 60062 SI prefixbut there are several exceptions, where the capitalization differs or alternative letters are used. The letters p and n weren’t part 60026 the first issue of the standard, but were added after the adoption of the corresponding SI prefixes.
Originally meant also as part marking codethis shorthand notation is widely used in electrical engineering to denote the idc of iec 60062 and capacitors in circuit diagrams and in the production iec 60062 electronic circuits for example in bills iec 60062 material and in silk screens. For brevity, the 600662 omits to always specify the unit ohm or farad explicitly and instead relies on implicit knowledge raised from the usage of specific letters either only for resistors or for capacitors, [nb 1] the case used uppercase letters are typically used for resistors, lowercase letters for capacitors[nb 2] a part’s appearance, and the context.
The letter and digit code for resistance and capacitance values and toleranceswhich is also known as RKM code  or “R notation”, is a notation to specify resistor and capacitor values defined in the international standard Iex formerly IEC 62 since For example, 8K2 indicates a resistor iec 60062 of 8.
Standard: IEC 60062
The introduction of the letter L in more recent issues of the standard instead of an SI prefix m for milli iec 60062 justified to maintain the rule of only using uppercase letters for resistances the otherwise resulting M was already in use for mega. Iec 60062 stems from the fact, that R is used in symbolic names for iec 60062 as well, and it is also used in a similar fashion but with incompatible meaning in other part marking codes.
From Wikipedia, the free encyclopedia. For example, 1R2 indicates 1. K k [nb 4].
When the value can be expressed without the need for a prefix, an “R” is used instead of the decimal separator. This is not only iec 60062 brevity for example when printed on the part or PCB iec 60062, but also to circumvent the problem that decimal separators tend to “disappear” when 60026 printed circuit diagrams. Date codes for and are obviously wrong. Retrieved from ” https: This section is empty.

Today, a lowercase letter m should be used for capacitances whenever possible to avoid confusion. Archived PDF from the original on Archived iec 60062 the original on R E [nb 3].
