Kingtronics offers high quality quartz crystal at incredibly aggressive prices. The HC49S series is an industry standard crystal package. HC49S is a low cost, low profile timing option for applications where cost is critical.

The HC49S is available in tight tolerances and stabilities for demanding applications. With a broad frequency range from 3.200MHz to 100.000 MHz, the HC49S can serve as a low cost solution in virtually any application or market.

The HC49S is available in through hole packaging only. For surface mount please see the HC49SMD series.

Quartz Crystal HC49S Applications

• CPU, Memory
• Computor, Printer
• Set-Top Box/Multimedia
• Modems, Clock/VCXO Multipliers

Specifying a Quartz Crystal

(Variables that must be selected by the design engineer)

Variable electrical parameters are those that the Design Engineer must specify when selecting a Quartz Crystal device for any particular application. a. Package Type: Will the package be Through Hole (Leaded Quartz Crystal HC49S & HC49U) or Surface Mount (SMD Quartz Crystal HC49SMD), and are there size constraints with either.

b. Frequency

c. Load Capacitance: The specified Load Capacitance is dependent on the Resonance Mode required in the application

d. Frequency Tolerance: an amount of initial frequency deviation acceptable for the application is required. Tighter specifications of Frequency Tolerance lower yield in quartz crystal Blank production thereby serving to increase production costs.

e. Stability: Over the Operating Temperature Range, an amount of total deviation acceptable for the application. Tighter specifications of Stability lower yield in Quartz Crystal Blank production thereby serving to increase production costs.

f. Operating Temperature: Standard Operating Temperature ranges are generally considered as -20-+70 degrees Celsius (considered "commercial" Operating Temperature), and -40-+85 degrees Celsius (considered "Industrial" Operating Temperature) Other Operating temperature ranges are available and should be specified and/or discussed with an Kingtronics sales.
