Our Counterfeit Mitigation in Practice

One counterfeit example we uncovered - TO5 Diode Array

These items were found to have a new lid installed over the old one to make it look like they were new.


Our testing procedures are always evolving to stay ahead of the ever changing Quality Control needs.
