Handling Notes for Crystal Oscillators
6. In order to use crystal oscillators
(1)The minlature crystal oscillator for the clock utillzes a C-MOS IC and incorporates a protective circuit against static electricity
However, exerclse care in the same manner as for a normal C−MOS IC.
(2)Internal capacitor is not provided in the power supply section (+DC−GNC).
To serve as overimpressed voltage and overcurrent protective device, place a bypass capacitor (0.01
µF)
as near as possible
to the (+DC−GND) terminal.
However, the capacity value is meant as a guideline.
Depending on the capacitor type, frequency characteristics vary. Accordingly, use a capacitor that matches the frequency
characteristics.
(3)Applying reverse voltage could result in damage to internal parts. Take care not to connect terminals incorrectly.
(4)Please do not use oscillators under unfavorable condition such as beyond specified range in catalog or specification sheet.
(5)Please keep oscillators away from water, salt water or harmful gas.
(6)K50H-3C / FSO series should be stored in humidity-controlled area after the package is unsealed, in temperature
+25±5˚C
under humidity of 65%RH, and should be mounted on PCB within 7 days.
(7)K50H-3C / FSO series has Bypass Capacitior between VDD and GND.
