Why you should buy quality electrical parts

It is good to evalute products to insure they meet required specifications. Specifications are often self governed. Lack of specifications often indicates hiding poor performance. As a product development engineer I did a bunch of testing. While many companies offer parts with the same part numbers and similar specifications, the difference in quality is often huge. Bill of materials are often very specific for reliable products. After much testing a few companies are identifed as favorites. With all the mergers, it gets more difficult these days.
