Crystals Procurement Notes

Verify the specific manufacturer datasheet to confirm the exact package dimensions and pin configuration before finalizing the PCB footprint. Ensure that the selected crystal holder or circuit design supports the required load capacitance of 10 pF to maintain the specified frequency accuracy. Cross-reference the ESR value with the oscillator circuit requirements to guarantee proper startup conditions.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required with tight initial tolerance specifications. The 10 pF load capacitance requirement must align with the host oscillator circuit's internal capacitance settings. Consider the 80 ohm ESR limit when designing the feedback loop to ensure adequate drive levels without overdriving the crystal element.

Crystals Part Context

This model belongs to the SMD crystal family offered by Shenzhen SCTF Electronics, targeting applications requiring stable high-frequency oscillation. The part number structure indicates specific parameters including frequency, tolerance, load capacitance, and package type, distinguishing it from other variants in the product line.

Crystals Replacement Considerations

Substitute parts must match the 40 MHz frequency, 10 pF load capacitance, and 4-SMD No Lead package dimensions. Verify that alternative components meet the same ±10 ppm tolerance and 80 ohm ESR specifications to ensure circuit compatibility.
