QUARTZ

Leaded crystal 11.5 x 4.9mm base

Low-cost, industry-standard crystal unit

Available to close tolerances

Frequency range 1.0MHz to 250MHz

A wide choice of package options available

HC49 Crystals

1.0MHz to 250.0MHz

DESCRIPTION

HC49 crystals are long-established, industry-standard crystals.

Standard HC49 crystals provide a very low cost source of system

clock frequency but they are also able to be produced to very close

tolerances where required. Several holder variants are possible.
