For many years, the MM49 unit was an industry-standard crystal, with advantages in size and cost. Although
smaller and newer designs have gained large acceptance, the reliable MM49 remains the most economical in
many applications. In addition, it can usually be designed to provide special motional parameter requirements,
such as VCXO pull, that smaller crystal units cannot match. So if cost is an issue, Monitor recommends the
rugged, resistance-welded MM49, and its surface-mountable partner, the SM49.
Monitor Products has a proven track record as a pioneer manufacturer
in the frequency control market. If our extensive selection of standard
and engineered crystals and oscillators does not meet your spec, we
will work with you towards a customized solution.
