Crystals Procurement Notes

Verify the specific suffix 'R' against the manufacturer's current documentation to confirm tape-and-reel packaging specifications. Ensure the 12 pF load capacitance matches the target circuit design requirements before integration. Cross-reference the 100 Ohm series resistance value with the oscillator driver strength capabilities.

Crystals Selection Notes

Select this component when a precise 18.432 MHz reference is required in a compact surface-mount form factor. The ±15 ppm tolerance offers higher precision than standard commercial crystals. Consider the 12 pF load capacitance requirement carefully to ensure accurate frequency operation within the host circuit topology.

Crystals Part Context

This part belongs to the C3E series of surface-mount crystals from Aker Technology Corp. The series provides various frequency options in standardized SMD packages. The C3E designation indicates a specific footprint and leadless termination style suitable for high-volume PCB manufacturing processes.

Crystals Replacement Considerations

Direct substitutes include other 18.432 MHz SMD crystals with identical 12 pF load capacitance and similar physical dimensions. Verify that alternative manufacturers offer comparable ±15 ppm tolerance and 100 Ohm series resistance to maintain circuit performance.
