DESCRIPTION
49USMX crystals are low profile surface mount crystals with the same
footprint as standard HC49 and HC49-4H crystals. 49USMX crystals
are ideal for use in low cost, mass-market applications but are also
able to be produced to close tolerances when required.
Low cost crystal for mass market applications
Surface mount version of HC49-4H crystal
Comprehensie stockholding of standard frequencies
Customized parts readily available
Industry-standard package
Low-profile versions available
