The code letters are loosely related to the corresponding SI prefixbut there are several exceptions, where the capitalization differs or alternative letters are used. Iec 60062 from lec iec 60062 on This method avoids overlooking the decimal separatorwhich may not be rendered reliably on components or when duplicating documents. List of International Electrotechnical Commission standards. The letters 600062 and n weren’t part of the first issue of the standard, but were added after the adoption of the corresponding SI prefixes.

From Wikipedia, the free encyclopedia.

iec 60062 When the value can be expressed without the need for a prefix, an “R” is used instead of the decimal separator.

Letter and digit code – Wikipedia

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 iec 60062, [nb 2] a part’s appearance, iec 60062 the context.

It stems 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 incompatible meaning in other part marking codes. Archived PDF from the original on K k [nb 4]. Today, a lowercase letter m should be iec 60062 for capacitances whenever possible to avoid confusion.

Standard: IEC 60062

Originally meant also as part marking codethis shorthand notation is widely used in electrical engineering to denote the values of iec 60062 and capacitors in circuit iec 60062 and in the production of electronic circuits for example in bills of material and in silk screens. The letter and digit code for resistance and capacitance values and toleranceswhich is also known as RKM code [1] or iec 60062 notation”, is a notation to specify resistor and capacitor values defined in the international standard IEC formerly IEC 62 since For example, 1R2 indicates 1.

Similar, the standard prescribes the following lowercase letters for capacitances to be used instead of the decimal point: This is not only for 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 photocopying printed circuit diagrams.

By using this site, you agree iec 60062 the Terms of Use and Privacy Policy. R E [nb 3]. For example, 8K2 indicates iec 60062 resistor value of 8. It may therefore cause confusion in some contexts. The iec 60062 updated IEC This page was last edited on 23 Julyat You can help by adding to it.

The standards also define a color code for fixed resistors. 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. Additional zeros imply tighter tolerance, for example 15M0.

However, the letter E is conflictive with the similar looking but incompatible E notation in engineering, and it iec 60062 therefore cause considerable confusion as well. This section is empty.

Date codes for and are obviously wrong. The notation also avoids using a decimal separator and replaces it by a letter associated with the prefix iec 60062 for the particular value.

Retrieved from ” https: Views Read Edit View history. 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 iec 60062 added after the adoption of iec 60062 corresponding SI prefixes.
