Re: It's not just Laptops and Smartphones
The unit of inductance is the Henry, capital H. He is referring to the hours (usually at 110C) rating for electrolytics.
Once upon a time in the far past when a piece of equipment from a (deceased) manufacturer came in for repair, whatever the fault we replaced all the small electrolytics on the mainboard with tantalums, and a certain failure prone carbon resistor with metal oxide. The point was that the OEMs crappy product affected our company image, and spending an extra hour avoiding future problems was always worth it in PR terms.
