Crystals Procurement Notes

Verify the specific ordering suffix KDZY-T against official TXC documentation to confirm exact electrical parameters, particularly load capacitance and ESR values, as variations exist within the 9HT12 family. Ensure compatibility with reflow soldering profiles specified in the datasheet. Cross-reference package dimensions and terminal configurations to match PCB layout requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a small form factor and moderate frequency accuracy are required for low-power applications. The 7 pF load capacitance necessitates careful circuit design to ensure oscillator stability. Consider the 90 kOhm ESR value when designing the load capacitors to meet the manufacturer's recommended oscillation conditions. Verify that the operating temperature range meets the environmental demands of the target application.

Crystals Part Context

This part belongs to the 9HT12 series of tuning fork crystals from TXC Corporation. These components are engineered for use in devices requiring accurate timekeeping or low-frequency reference signals. The series offers various load capacitance and tolerance options to suit different oscillator circuit designs while maintaining a consistent small SMD package profile.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 7 pF load capacitance, ±20 ppm tolerance, and 2-SMD 3.2x1.5mm package dimensions. Verify equivalent ESR and temperature range specifications. Consult TXC official documentation for approved alternative part numbers within the same product line.
