TUTORIAL - SPECIFYING STOCK PARTS



 
In this example, we'll specify a low power, 100 ohm, 5%, 1/4 W, leaded resistor.
 
100 ohm leaded resistor

 
Make a selection in each tool, from top to bottom.

 
As this is a standard resistor (not a precision one), select "Standard".

 
Standard resistor

 
To select a standard value in the E6 series (6 values per decade), select "E6 Standard".

 
E6 Standard values

 
Click the field with the value.

 
Click value field

 
Select the significant value of the resistor's value from the 2-D pop-up that appears: select "100".

 
Select from 2-D pop-up

 
ALTERNATIVELY: To enter the value directly, select "Enter directly".

 
Or: select Enter Directly

 
Click the field with the value and enter the value directly.

 
Enter value directly

 
Select the units for the resistor's value: select "Ohms".

 
Select Ohms

 
Select how the resistor is mounted: select "Thru-hole".

 
Select Thru-hole

 
Select the type of resistor: select "Carbon film".

 
Select Carbon film

 
Select how the resistor's tolerance: select "5 %".

 
Select 5 %

 
Select the resistor's case: select "RC07 (1/4 W)" (RC07 is the industry designation for that package size).

 
Select RC07 (1/4 W)

 
The Results panel, at the bottom, displays a description and a Part Number for your selections.
