Past 3 companies?!? What? How do you handle diodes, LEDs, batteries, and electrolytic caps? Those are also two terminal devices with polarity. Heck how did you

Past 3 companies?!? What? How do you handle diodes, LEDs, batteries, and electrolytic caps? Those are also two terminal devices with polarity. Heck how did you even build cables correctly? I've worked with voltage regulators from Linear that explicitly call out using tantalum caps in the recommended design.
