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.
