Just low profile crystals?
Uhm....... it's crystal 8)
Yes, it's a pretty common package size. Another common package you'll see alot of has the same width and spacing but taller. Not sure if that's the answer you're looking for or not.
I've never built anything that uses crystals and I've never even held a crystal in my hand, so I didn't know they came in different sizes. I've only seen the taller ones and when I came across these I wasn't sure if they were the same thing as what I've seen. Thanks for the reply.
