20.000MHZ HC49/4H/30/50/40/18PF/ATF Euroquartz

QUARTZ EURO HC49-4H and HC49-4HL Crystals Low-cost, industry-standard crystal unit AT-Cut strip crystal with hermetically sealed can Frequency range 1.0MHz to 70MHz Package height options available DESCRIPTION HC49-4H crystals share the same base outline as the industry- standard HC49 crystal. The crystal uses at AT-cut strip crystal with an hermetically sealed can. HC49-4H crystals provide a low cost source of system clock frequency.
