Originally meant also as part marking code, this 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).
A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.
Electronic color code#Capacitor code From an alternative name : This is a redirect from a title that is another name or identity such as an alter ego, a nickname, or a synonym of the target, or of a name associated with the target.
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
English: Schematic of a parallel plate capacitor with a dielectric spacer. Two plates with area A {\displaystyle A} are separated by a distance d {\displaystyle d} . When a charge ± Q {\displaystyle \pm {}Q} is moved between the plates, an electric field E {\displaystyle E} exists in the region between the plates.
Name mapping in SPEF is not required. Also, mapped and non-mapped names can appear in the same file. Typically, short names such as a pin named A will not be mapped as mapping would not reduce file size. One can write a script to map the numbers back into names. This will make SPEF easier to read, but greatly increase file size.
