    FEATURES
    GENERAL SPECIFICATION
    DESCRIPTION
    HC49 crystals are a long-established industry-standard part. Basic
    specification HC49 crystals provide the lowest cost crystal available but
    these crystals can also be manufactured to very close tolerances and low
    ESR values. Holder variants are HC49/T (truncated), providing a lower
    height version, 3-wire versions where the crystal base and body can be
    earthed by a centre earth wire and HC50 which has larger diameter leads
    specifically for socket mounting.
