Crystals Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct tolerance and packaging specifications. Confirm that the 4-SMD J-Lead form factor matches the target PCB footprint requirements. Ensure compliance with RoHS exemption status aligns with project regulatory needs. Cross-reference the ESR and load capacitance values with circuit design parameters before finalizing procurement orders.

Crystals Selection Notes

Select this component when a precise 32.768 kHz reference is required for low-power digital logic or real-time counting applications. The ±20 ppm tolerance offers adequate stability for general-purpose timing tasks without requiring expensive oven-controlled solutions. The small 7.0x1.5 mm footprint makes it suitable for space-constrained portable devices. Consider the 65 kOhm ESR when designing oscillator circuits to ensure reliable startup conditions.
