explaining the joke
Würth Elektronik is one of the biggest manufacturers of passive components in the electronics world. they're particularly known for their inductors, but they also make capacitors and connectors, among other things
Vishay is probably their biggest competitor; they're particularly known for resistors, but they also make capacitors, transistors, relays, and lots of other stuff

vishay re: explaining the joke
vishay is.... weird
they made some of the highest quality resistors you could get on their own originally, but they also bought out a *lot* of other really prestigious companies
so you have Vishay Sprague making capacitors, Vishay Dale making resistors, Vishay Beyschlag/Draloric/BC Components making other resistors, Vishay Siliconix making transistors, Vishay Sfernice making relays
