• Fundamental mode operation providing stable timing signals at 12.0 MHz with low profile dimensions suitable for space-constrained PCB layouts.
• Compliance with environmental regulations including RoHS3 and REACH status, ensuring suitability for modern manufacturing processes.

Applications

• Clock generation circuits in microcontroller-based embedded systems
• Timing references for communication interfaces such as UART or SPI
• General-purpose oscillator sources in consumer electronic devices

Procurement Notes

Verify the specific suffix designation against official IQD documentation to confirm packaging configuration, as bulk variants may differ in handling requirements. Ensure that the selected part number matches the required frequency tolerance and load capacitance specifications for the target circuit design. Cross-reference the manufacturer's latest datasheet to confirm current production status and any potential obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when a 12.0 MHz fundamental frequency crystal is required for surface-mount assembly. The 18 pF load capacitance must align with the oscillator circuit's external capacitor values to achieve accurate frequency performance. Consider the 70 Ohm ESR value when designing the drive level constraints to prevent over-driving the crystal. The -40°C to +85°C temperature range should be sufficient for most commercial and industrial applications requiring standard stability.

Part Context

This part belongs to the CFPX-104 series of SMD quartz crystals from IQD Frequency Products. The series is characterized by its small footprint and robust construction, often featuring a seamed, sealed metal lid for enhanced protection. These components are widely used in applications demanding reliable timing solutions within limited board space, offering a balance between performance and physical size constraints common in modern electronics.

Replacement Considerations

Direct substitutes include other 12.0 MHz SMD crystals with identical 18 pF load capacitance and compatible package dimensions. Verify that alternative parts meet the same ±30 ppm tolerance and operate within the specified temperature range. Check for matching ESR values to ensure circuit compatibility. Consult the manufacturer's cross-reference list for officially confirmed equivalent part numbers before substitution.
