THROUGH-HOLE CRYSTALS

HC51 SERIES CRYSTALS

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.
