segor.de goes one better and just downloads the entire catalogue when you first open it. About 2MB decompressed. Clicking and even searching is instant because it's all fully client side until you place an order.

Funny thing is it apparently predates JSON. It's a bunch of data[foo][bar] = baz; - go look.

(Website's in German obviously, and a surprising number of German electronic terms are very different from English. They use two different words for stranded and non-stranded wire.)
