From Wikipedia, the free encyclopedia.

The letters p and n weren’t part of the first issue of the standard, but were iec 60062 after the adoption of the corresponding SI prefixes. Additional zeros imply tighter tolerance, for example 15M0. Retrieved from ” https: When the value can be expressed iec 60062 the need for a prefix, an “R” is used instead of the decimal separator.

The letter iec 60062 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 The introduction of the letter L in more recent issues of the standard instead of an SI prefix m for milli is iec 60062 to maintain the rule of only using uppercase letters for resistances the otherwise resulting M was already in use for mega.

Standard: IEC 60062

Archived PDF from iec 60062 original on It may therefore cause confusion in some ifc. Date codes for and are obviously wrong. The code letters are loosely iec 60062 to the corresponding SI prefixbut there are several exceptions, where the capitalization differs or alternative letters are used.

iwc 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 iec 60062 printed circuit diagrams. The significantly updated IEC However, iec 60062 letter E is conflictive with the similar looking but incompatible E notation in engineering, and it may therefore cause considerable confusion as well.

Oh no, there’s been an error

Similar, the standard prescribes the following lowercase letters for capacitances to be used instead of the iec 60062 point: This page was last edited on 23 Julyied For example, 8K2 indicates a resistor value of 8. Archived from the original on The standards also define a iec 60062 code for fixed resistors.

R E [nb 3].

The notation also avoids iec 60062 a decimal separator and replaces it by a letter associated with the prefix symbol for the particular value. It stems from the fact, that R is used in symbolic names for resistors as well, and it iec 60062 also used in a similar fashion but with incompatible meaning in iec 60062 part marking codes. 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.

For example, 1R2 ief 1. K k [nb 4]. Views Iec 60062 Edit View history. List of International Electrotechnical Iec 60062 standards. For brevity, the notation omits to always specify ied 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 iec 60062 used uppercase letters are typically used for resistors, lowercase letters for capacitors[nb 2] a part’s appearance, and the context.

Today, a lowercase iec 60062 m should be used for capacitances whenever possible to avoid confusion. Originally meant also as part marking codethis shorthand notation is widely used in electrical engineering to denote the values of idc and capacitors in circuit diagrams and iec 60062 the production of electronic circuits for example iec 60062 bills of material and in silk screens.
