SMD form of HC49 Crystals
Low-cost, industry-standard crystal unit formed for SMD
Available with close tolerances
Frequency range 1.0MHz to 200MHz
Specifications fully customisable
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.
