Crystals Procurement Notes

Verify the specific ordering suffix to ensure compliance with required environmental standards and tape/reel packaging specifications. Confirm that the load capacitance matches the oscillator circuit design requirements. Check for RoHS compliance status if restricted substances are prohibited in the target application environment.

Crystals Selection Notes

Select this component when a 32 kHz reference signal is required for timekeeping functions. Ensure the system oscillator supports the specified 12.5 pF load capacitance. Consider the ±30 ppm tolerance against the overall system accuracy requirements. Evaluate the 4-SOJ footprint compatibility with the printed circuit board layout constraints.

Crystals Part Context
