Crystals Procurement Notes

Verify exact frequency tolerance and stability specifications against the manufacturer's current datasheet, as values may vary based on specific ordering suffixes or production batches. Confirm package dimensions and pinout compatibility with target PCB layout. Ensure lead-free soldering profiles are utilized during assembly to maintain RoHS compliance and device integrity. Cross-reference part numbers carefully to distinguish between similar ILCX series variants with differing electrical characteristics.

Crystals Selection Notes

Select this component for applications requiring precise timing in compact surface-mount designs. Consider the 150 ohm ESR limit when designing oscillator circuits to ensure reliable startup. Evaluate thermal requirements against the -40°C to +85°C operating range. Compare load capacitance requirements with the host circuit's input capacitance to maintain frequency accuracy. Assess aging rates if long-term stability is critical for the application timeline.

Crystals Part Context

The ILCX20 series represents ILSI America's line of miniature quartz crystals designed for high-volume consumer and industrial electronics. These components utilize AT-cut resonators housed in small form-factor packages.
