Crystals Procurement Notes

Verify current availability status as supply may be limited or subject to discontinuation notices. Confirm that the specific 20 pF load capacitance matches your circuit design requirements. Ensure the 40 Ohm ESR value is compatible with your oscillator's start-up conditions. Check for any recent Product Change Notifications (PCN) regarding manufacturing updates.

Crystals Selection Notes

Select this component when a small form factor is critical for PCB layout efficiency. It is suitable for applications requiring stable timing in consumer electronics and wireless modules. Consider the ±50 ppm stability if higher precision is not required. Verify that the 1 mW maximum drive level aligns with your system's power consumption constraints.
