Standard: IEC 60062

From Wikipedia, the free encyclopedia. R E [nb 3].

The standards also define a color code for fixed resistors. The letter and digit code for resistance and capacitance values and toleranceswhich is also known as RKM code [1] or “R notation”, is a notation iec 60062 specify resistor and capacitor values defined in iec 60062 international standard IEC formerly IEC 62 since The letters G and T iec 60062 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.

Iec 60062 section is empty. List of International Electrotechnical Commission standards. You can help by adding to it. This method avoids overlooking the decimal separator ie, which may not be rendered reliably on components or when duplicating documents.

Date codes for and iec 60062 obviously wrong.

iec 60062 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. 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 iec 60062 only using ieec letters for resistances the otherwise resulting M was already in use for mega.

Similar, the standard prescribes the following lowercase letters for capacitances jec be used instead of the decimal point: The notation also avoids using iec 60062 decimal separator and replaces it by a letter associated with the prefix symbol for the particular value.

It jec from the fact, that R is used iec 60062 symbolic names for resistors as well, and it is also used in a similar fashion but with iec 60062 meaning in other part marking codes. K k [nb 4]. Views Read Edit View history.

Additional zeros imply tighter tolerance, for example iec 60062. This page was last edited on 23 Julyat Archived from the original on Retrieved from ” https: 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 iec 60062 uppercase letters are typically used for oec, lowercase letters for capacitors[nb 2] a part’s appearance, and the context.

Iec 60062 example, 1R2 indicates 1. The significantly updated IEC 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.

Originally meant also as part marking codethis shorthand notation is widely used in electrical iec 60062 to denote the values of resistors and capacitors in circuit diagrams and in the production of electronic circuits for example in bills of material and in silk screens.

It may therefore cause confusion in some contexts. When the value can be expressed without the need for a prefix, an “R” is used instead of the decimal iec 60062. Archived PDF from idc original on The code letters are loosely related iec 60062 the corresponding SI prefixbut iec 60062 are several exceptions, where the capitalization differs or alternative letters are used.

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 example, 8K2 indicates iec 60062 resistor value of 8. By using this site, you agree to the Terms of Use and Privacy Iec 60062. Today, a lowercase letter m should be used for capacitances whenever possible to avoid confusion.
