DESCRIPTION
74USMX crystals are low profile surface mount crystals with a 50% reduced footprint over the popular 49USMX type crystals. 74UMX crystals are ideal for use in low cost, mass-market applications. Low profile, reduced size SMD crystal Reduces footprint of 49USMX crystals by 50% Customized parts readily available
