The top of each Richtek product is marked with our coding system. The picture below shows a sample of our IC code.

This coding system is applied daily to our IC. It is crucial to non-conforming parts control and quality control tracking. Our coding can also be found on the label of boxes, reels and cartons as shown in the picture above. This system will generate unique codes for a 14 year time period. Production history is retained in an Oracle database. Production history can be traced effectively and efficiently by a single IC. Smaller ICs, like SOT-2X, are marked with a series of dots. Please contact our account manager for details on our coding system.
