For iec 60062, 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] iec 60062 part’s appearance, and the context.
This method avoids overlooking kec decimal separatorwhich may not be rendered reliably on components or when duplicating documents.
iec 60062 The letter and digit iec 60062 for resistance and capacitance values and toleranceswhich is also iec 60062 as RKM code  or “R notation”, is a notation to specify resistor and capacitor values defined in the international standard IEC formerly IEC 62 since This section is empty.
From Wikipedia, the free encyclopedia. Today, a lowercase letter m should be used for capacitances whenever possible to avoid ieec.
Archived PDF from the original on This page was last edited on 23 Iec 60062at Additional zeros imply tighter tolerance, for example 15M0. Originally meant also as part marking codethis shorthand notation is widely used in electrical engineering 60062 denote the values of resistors and capacitors in circuit diagrams and in the production of iec 60062 circuits for example in bills of material and iec 60062 silk screens.
It stems from the fact, that R is used in symbolic names for resistors as well, and it is also used in a similar iec 60062 but with incompatible meaning in other part marking codes. Views Read Edit View history. K k [nb 4].
Letter and digit code
iec 60062 You can help by adding to it. The letters p and n weren’t part 6002 the first issue of the standard, but were added after the adoption of the corresponding SI prefixes. It may therefore cause confusion in some contexts. When the value can be expressed without the need for a 6062, an “R” iec 60062 used instead of the decimal separator.
The standards also define a color code iec 60062 fixed resistors. For example, 1R2 indicates 1.
The letters G and T weren’t part of iec 60062 first issue of the standard, which pre-dates the introduction of the SI system hence the name “RKM iec 60062but were added after the adoption of the corresponding SI prefixes.
The code letters are loosely related to the corresponding SI prefixbut there are several exceptions, iec 60062 the capitalization differs or alternative letters are used. The introduction ic the letter L in more recent issues of the standard instead of an SI prefix m for milli is justified to maintain the 6062 of only iec 60062 uppercase letters for resistances the otherwise resulting M was already in use for mega.
Date codes for and are obviously wrong. Archived from the original on The significantly updated IEC However, the letter E is conflictive iec 60062 the similar looking but incompatible E notation in engineering, and it may therefore cause considerable confusion as well. 6006

This is not only for brevity for example when printed on the part or PCBbut also iec 60062 circumvent the problem that decimal separators tend to “disappear” when photocopying printed circuit diagrams.

Similar, the standard prescribes the following lowercase letters for capacitances to be used instead of the decimal point: R E [nb iec 60062.
