Crystals Procurement Notes

Verify the specific suffix 'EB' against official Suntsu documentation to confirm exact electrical tolerances and packaging variations. Ensure the required frequency stability meets the target application's phase noise requirements. Cross-reference the HC-49/US footprint dimensions with PCB design files before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 12 MHz reference signal is required with moderate stability specifications. The HC-49/US form factor suits applications needing robust mechanical mounting. Consider the ±15ppm tolerance limit against system clock accuracy requirements. Evaluate the 60 Ohm ESR compatibility with the driving circuit's impedance matching needs.

Crystals Part Context

This part belongs to the Suntsu Electronics crystal oscillator family designed for general-purpose timing applications. It complements other models in the series offering different frequencies or tighter stability grades. The HC-49/US package provides a standardized solution for legacy and modern PCB layouts requiring through-hole mounting.

Crystals Replacement Considerations

Direct substitutes must match the 12 MHz frequency, HC-49/US package, and 18pF load capacitance. Verify that alternative manufacturers offer comparable ±15ppm tolerance and 60 Ohm ESR values. Ensure thermal performance remains within the -40°C to +85°C range for valid replacement scenarios.
