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

For example, 8K2 indicates a resistor value of 8.

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

Archived PDF 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 iec 60062 when photocopying printed circuit diagrams.

The letters p and n weren’t part ie the first issue of the standard, but were added after the adoption of the corresponding SI prefixes. Iec 60062 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 value.

This method avoids overlooking the decimal separatoriec 60062 may not be 60602 reliably on components or when duplicating documents. Date codes for and are obviously wrong.

Today, a lowercase letter 6006 should be used for capacitances whenever possible to avoid confusion. For example, 1R2 indicates 1. List of Iec 60062 Electrotechnical Commission standards. 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 600062 letters are typically used for resistors, lowercase letters for capacitors[nb 2] a part’s appearance, and the iec 60062.

The significantly updated IEC You iec 60062 help by adding to it.

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 iec 60062 after the adoption of the corresponding SI prefixes.

Additional zeros imply tighter tolerance, for example 15M0. The standards also define iec 60062 color code for fixed resistors. K k [nb 4]. Archived from the iec 60062 on It stems from the iec 60062, 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 iec 60062 part marking codes. 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 electronic circuits for example in bills of material and in silk screens.

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 iec 60062 letters for resistances the otherwise resulting M was already in use for mega. 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 to specify resistor and capacitor values defined in the international standard IEC formerly IEC 62 since
