DESCRIPTION
HC51 crystals are long-established standard crystals in the industry. Basic
specification HC51 crystals provide low frequencies at relatively low cost
and have the advantage of low ESR values. A holder variant is the HC48
which has larger diameter leads specifically for socket mounting.
