MiscEl: Prefered components

Back to MiscEl main page Write a message to author


This page is used to define the standard values used when designing circuits and what steps Ctrl-m and Ctrl-n are using.
Most designs are aware of the settings on this page and will adjust designs depending on selections here.

Standard values supported

When going from E3, E6, E12 to E24, each succeding standard will have all the values from the lower standards. The same is true from E48, E96 to E192. But between E24 and E48 the standard values changes from two to three digits, preventing an excact match for all values.
Most manufactures are following these E-rows when producing resistors, capacitors and inductors.

Input values

Round resistors toThis setting is to round resistor values for most circuits designs
and to define steps for Ctrl-m and Ctrl-m in many resistor input fields
Round capacitors toThis setting is to round capacitor values for most circuits designs
and to define steps for Ctrl-m and Ctrl-m in many capacitor input fields
Round inductors toThis setting is to round inductor values for most circuits designs
and to define steps for Ctrl-m and Ctrl-m in many capacitor input fields
Step sizeThis setting is used to define step size for Ctrl-m and Ctrl-n in many fields


Hints

Most pages are using these settings, both for displaying values and for Ctrl-m and Ctrl-n step size.

Calculator functions

The Calculator has functions to convert a number to a standard value:
StdR(Value)
StdC(Value)
StdL(Value)
StdE3(Value)
StdE6(Value)
StdE12(Value)
StdE24(Value)
StdE48(Value)
StdE96(Value)
StdE192(Value)
