Crystals Procurement Notes

Verify the exact part number suffix against official HKC documentation to confirm package type and tape/reel specifications. Ensure compatibility with peak reflow temperature profiles defined in the datasheet. Confirm that the load capacitance requirements of the target circuit match the 15 pF specification to maintain frequency accuracy. Cross-reference the ESR value with oscillator circuit designs to ensure proper startup conditions.

Crystals Selection Notes

Select this component when a 38.4 MHz reference is required for digital logic timing. The ±10 ppm tolerance suits applications needing moderate stability without the cost of higher-grade oscillators. The 4-SMD form factor is ideal for PCBs with limited real estate. Consider the -20°C to +70°C range against environmental conditions; if wider temperatures are needed, check for alternative HKC variants rated for industrial or extended ranges.

Crystals Part Context

This crystal belongs to HKC's SMD crystal lineup, characterized by small footprints and leadless construction. The '3225' designation typically indicates approximate dimensions, though specific measurements should be verified in the mechanical drawings. As a passive frequency control element, it differs from active oscillators by requiring an external amplifier circuit within the host system to generate a square wave output.

Crystals Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, 15 pF load capacitance, and 4-SMD package. Verify that any replacement part meets the same ±10 ppm tolerance and 50 Ohm ESR specifications. Check thermal ratings to ensure equal or better temperature stability. Consult manufacturer cross-reference lists for approved equivalents that maintain electrical and mechanical compatibility.
