CSM-3x/HC-46x Miniature Quartz Crystals

ECS 3x/46x Low Profile Miniature Quartz Crystals are cost-effective and available in two series, the CSM-3X and the HC-46X. The HC-46X Series weld type through-hole quartz crystals reduce the footprint of HC-49USX by 50%. The CSM-3X Series is the miniature low profile resistance weld type SMD quartz crystal and reduces the footprint of CSM-7X (HC-49USX SMD) by 50%. Both the ECS CSM-3X and HC-46X Quartz Crystals are lead-free and ROHS compliant.
