THROUGH-HOLE CRYSTALS

HC49 SERIES CRYSTALS

DESCRIPTION

OUTLINES & DIMENSIONS

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.
