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
