49SMD Standard and Low Profile

FEATURES

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

49USMX CRYSTALS

3.2MHz to 70.0MHz

OUTLINE & DIMENSIONS

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.
