Crystals Procurement Notes

Verify that the specific ordering suffix matches the required load capacitance and tolerance specifications for your circuit design. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management guidelines are followed during soldering to maintain frequency stability within specified limits across the operational temperature range.

Crystals Selection Notes

Select this component when a 12 MHz reference signal is required with moderate stability requirements. The 18 pF load capacitance must align with the oscillator circuit's input capacitance to ensure accurate frequency tuning. Consider the 90 Ω ESR value when evaluating drive level sensitivity and startup time constraints in the target application environment.

Crystals Part Context

This part belongs to the C5S series of surface-mount crystals from Aker Technology Corp. The series offers various frequency options and package sizes tailored for compact electronic designs. The C5S designation indicates a specific form factor and mounting style suitable for high-volume production environments requiring reliable timing components.

Crystals Replacement Considerations

Substitute parts must match the 12 MHz frequency, 18 pF load capacitance, and 4-pin SMD package dimensions. Verify equivalent electrical parameters such as ESR and stability ratings to ensure circuit compatibility without redesign.
