In this paper, the necessity and key questions for detection of counterfeit components is being described. Main goal is to inform professionals from academic as well as from industry sector how to detect counterfeit parts and be confident with evaluation. For these purposes some standard and some more specific methods are described more in detail. Electrolytic capacitors are very often used in the electronic equipment’s in wide range of products including computers, medical equipment, automobiles, avionics and military systems due to their high capacitance to volume ratio. This study examines suspicious samples of aluminum electrolytic capacitor purchased on open market that were unknowingly assembled in power supplies. Based on the systematic detection methodology, the counterfeit components were identified, and their reliability relative to genuine parts was assessed.
