49SMD Crystals

SMD form of HC49 Crystals

1.0MHz to 200.0MHz

Low-cost, industry-standard crystal unit formed for SMD

Available with close tolerances

Frequency range 1.0MHz to 200MHz

Specifications fully customisable

OUTLINE & DIMENSIONS

DESCRIPTION

49SMD crystals are long-established, industry-standard HC49 crystals

with formed leads and a clip to facilitate surface mounting. The

crystals provide a high quality but very low cost source of system

clock frequency 49SMD crystals may be produced to very close

tolerances.
