Imperial code VS metric code - SMD size difference?  Find out & get your free SMD size chart 

The two different ways to specify the component sizes can be a challenge for buyers of components - but just as important you chose what new pick & place machinery to buy.

As a SMT machine supplier we understand how crucial it is that you know the difference. We take pride in giving our customers the correct guidance to make their basis for decision the best possible.

So when we tell you that our YAMAHA YSM20 machine supports 0201 component in metric code - do you know how tiny that SMD component is?

Metric or Imperial components
- what is the difference in SMD sizes?

It can cause some confusion,  but it's actually very simple, as the number code on the component is the component size. This is the case both with Imperial or metric code:

• Imperial code is in inches
  Example: 0201 imperial component. 
  This means that the component is 0,02 x 0,01 inches.
  
  

• metric code is in millimeter 
  Example; 0201 metric component.
  This means that the component is 0,2 x 0,1 mm in size.
