Crystals Procurement Notes

Verify the specific suffix 'X-R' against official manufacturer documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with existing circuit load capacitance requirements before procurement. Cross-reference the part number with authorized distributors to validate authenticity and traceability. Confirm that the operating temperature range meets the environmental constraints of the target application. Request updated datasheets directly from Aker Technology Corp to ensure access to the latest revision details and electrical parameters.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 7.3728 MHz applications with tight frequency tolerance. The 12 pF load capacitance must match the oscillator circuit design to achieve accurate frequency output. Consider the 110 ohm ESR value for impedance matching within the resonant circuit. The surface-mount form factor suits high-density PCB layouts. Verify that the drive level specification aligns with the oscillator's output power to prevent overdriving the crystal element.
