SURFACE-MOUNT CRYSTALS
49MJ CRYSTALS
Surfa ce -m oun t HC49
OUTLINES AND DIMENSIONS
DESCRIPTION
49MJ crystals are standard HC49 crystals with formed leads, fitted with a
clip to enable surface-mount PCB assembly. The crystal therefore offers
the ease of surface-mount assembly with the technical benefit of close-
tolerance crystal parameters achievable by the use of circular AT-Cut
crystal blanks in the HC49 crystal.
