Help identifying some crystals

Guest
I work for an electronic component distributor and have an excess
inventory of crystals. I'm hoping someone can help me identify them.
Our inventory shows them as bing manufactured by MB. The part numbers
are MB3050HA33000MHZ and MB3100H12288MHZ. We're used to selling parts
from Xilinx, TI, 3M, etc.; so these are a little outside our typical
product lines. I'm hoping someone can help identify the manufacturer,
what they're used for, etc. I can send or post photos if necessary.
Thanks.

It appears that they are 33.000 MHz & 12.288 MHz A simple crystal
tester & frequency counter would mke sure. Used crystal testers were
all over the place a couple years ago as pagers became less popular.

was very popular. Ramsey has discontinued this, but still has them
listed on their closeout page. There are schematics online to build
your own for about $10, or you can pay Ramsey's price.

Can I guess(tm)? Those numbers don't look like individual crystals.
The look more like crystal can clock oscillators. No clue who MB
might be. The part number looks like something from MMD:
<http://www.mmdcomp.com>
Google finds these parts made by MMD, but I couldn't find the specific
part number series listed on their web pile.

MB3050HA33000MHZ = 33.000 MHz
MB3100H12288MHZ = 12.288 MHz

Wow - I didn't know if I'd get a response and these are great.

Thanks guys. @Jeff, you are correct that they are 12.288 Mhz and
30.000 Mhz.

Ok, so I have about 60,000 of them between the two parts. Any
suggestions on what I can do with them or who might be interested in
buying them?

Sell them back to the manufactory that made them for perhaps 5-10% of
their OEM selling price. They can then run them through their
production test and sell them as "remanufactured" parts. It's cheaper
for them to buy them back than to make new components. One of my
friends was fairly successful at doing this before 2000 when the
economy was better. No clue if it will work today. Otherwise,
contact a components broker and see if they're interested.
