Crystals Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's official datasheet to confirm RoHS compliance status and exact frequency tolerance specifications. Ensure that the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Cross-reference the part number with authorized distributors to confirm current availability and lead times prior to finalizing procurement plans.

Crystals Selection Notes

Select this component when a 27 MHz reference signal is required for surface-mount designs. The 12 pF load capacitance must match the oscillator circuit design parameters. Verify that the operating environment stays within the specified -40°C to +85°C range. Consider the 50 Ohm ESR value when evaluating circuit stability and startup conditions for the target application.

Crystals Part Context

This part belongs to the FH series of quartz crystals from Diodes Incorporated. It is distinct from other series such as FL or F6, which may offer different package sizes or frequency ranges. The FH series specifically targets general-purpose timing applications requiring small form factors and reliable performance in consumer and industrial electronics.

Crystals Replacement Considerations

Consult the official datasheet for direct pin-compatible substitutes within the same series. Verify that any alternative part matches the 27 MHz frequency, 12 pF load capacitance, and SMD-4 package dimensions to ensure mechanical and electrical compatibility.
