[time-nuts] How to read Isotemp OXCO131 part numbers?

[Chris Albertson]

Anyone know how to read Isotemp OXCO131 part numbers?

For example on eBay there are 131-2, 131-1, 131-100, and 131-191  All the
sellers refer you to the same specification PDF file.  But the fie just
says that there are many options but does not relate them back to what
you'd see printed on a label.

The 131 type units seem to be the best of the $20 and under OCXOs, I think.
 They run on only 1.5w of power which I like.

The spec file is here:
