• Telecommunications equipment needing reliable timing sources

Crystals Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when placing orders. Confirm that the 100 Ohm ESR specification aligns with circuit requirements. Ensure the -40°C to +85°C temperature rating meets environmental constraints. Cross-reference the 4-SMD footprint against the target board layout. Validate RoHS compliance status through official manufacturer documentation prior to integration.

Crystals Selection Notes

Select this component for designs requiring a compact 3.2x2.5 mm crystal with 27 MHz operation. The 18 pF load capacitance must match the oscillator circuit's external capacitors. Consider the 100 Ohm ESR limit for drive level sensitivity. The wide temperature range supports harsh environments. Compare against similar 8Y or 8Z series parts if different ESR values are needed.

Crystals Part Context

This part belongs to the 8Q series of ultra-miniature crystals from TXC Corporation. The series focuses on thin profiles and low series resistance for modern electronics. It complements other SMD crystals like the 7M and AM series, offering specific dimensional and electrical characteristics tailored for high-density surface-mount assembly in consumer and industrial devices.
