Crystals Applications

• Precision circuitry requiring stable clock signals
• Consumer electronics with limited board space
• Communication modules utilizing 27.12 MHz frequencies

Crystals Procurement Notes

Verify the specific suffix 'M' corresponds to the standard tape-and-reel packaging configuration as indicated in distributor listings. Confirm that the 9pF load capacitance aligns with the target oscillator circuit design requirements before finalizing procurement orders to ensure proper frequency accuracy.

Crystals Selection Notes

Select this component when a small form factor is critical alongside moderate stability requirements. The 150 Ohm ESR value should be compatible with the driving circuit's gain capabilities. Consider the 4-SMD no-lead package for automated assembly processes where minimal footprint is a priority.

Crystals Part Context

This part belongs to the SXT114 series of ultra-compact crystals from Suntsu Electronics. It shares the physical footprint characteristics with other variants in the series but differs in frequency and electrical parameters. The series is engineered for high-volume consumer applications requiring consistent timing sources.

Crystals Replacement Considerations

Direct substitutes must match the 27.12 MHz frequency, 9pF load capacitance, and 4-SMD no-lead package dimensions. Verify ESR compatibility with existing oscillator circuits. Cross-reference with other manufacturers offering similar miniature crystal packages if supply constraints exist.
