HC-49/U-S
Miniature Quartz Crystal Unit for Microprocessor Model HC-49/U-S
■Features
¡Height 3.5mm, the volume is compact at about one-fourth that of
the former product (HC-49/U).
¡A resistance weld completely sealed type.
¡The frequency stability is good, the reliability is high.
¡Multiple standard frequencies.
¡Copes with high density mounting and is optimum for mass
production models.
