When the value can be expressed without the need for a prefix, an “R” is used instead of the decimal separator. Retrieved from ” https: The code letters are loosely related to the corresponding SI prefixbut there are several exceptions, where the capitalization differs or alternative letters are used.

However, the letter E is conflictive with the similar looking but incompatible E notation in engineering, and it may therefore cause considerable confusion as well.

K k [nb 4]. List of International Electrotechnical Commission standards. Views Read Edit View history. Similar, the standard prescribes the following lowercase letters for capacitances to be used instead of the decimal point: From Wikipedia, the free encyclopedia.

The introduction of the letter L in more recent issues of the standard instead of an SI prefix m for milli is justified to maintain the rule of only using uppercase letters for resistances the otherwise resulting M was already in use for mega.

It stems from the fact, that R is used in symbolic names for resistors as well, and it is also used in a similar fashion but with incompatible meaning in other part marking codes. The standards also define a color code for fixed resistors.

The significantly updated IEC R E [nb 3]. You can help by adding to it. For example, 1R2 indicates 1. 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”but were added after the adoption of the corresponding SI prefixes.

The RKM code[1] also referred to as “letter and digit code for resistance and capacitance values and 6062 or “R notation”, is a notation to specify resistor and capacitor values defined in the international standard IEC formerly IEC 62 since Today, a lowercase letter m should be used for capacitances whenever possible to avoid confusion. Date codes for and are obviously wrong.

Oh no, there’s been an error

Originally meant also as part marking codethis shorthand notation is widely used in electrical engineering to denote the values of resistors and capacitors in circuit diagrams and in the production of 600062 circuits for example in bills of material and in silk screens.

For example, 8K2 indicates a resistor value of 8. The letters p and n weren’t part of the first issue of the standard, but were added after the adoption of the corresponding SI prefixes. This method ice overlooking the decimal separatorwhich may not be rendered reliably on components or when duplicating documents.

It may therefore cause confusion in some contexts. The notation also avoids using a decimal separator and replaces it by a letter associated with the prefix symbol for the particular 6006. Archived from the original on This is not only for brevity for example when printed on the part or PCBbut also to circumvent the problem that decimal separators tend to “disappear” when photocopying printed circuit diagrams.

For brevity, the notation 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.

Additional zeros imply tighter tolerance, for example 15M0.
