Resonators Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure compatibility with required tolerance and temperature specifications. Confirm RoHS compliance status through official datasheets prior to procurement. Ensure the supplier provides traceable origin documents for electronic components to guarantee authenticity and performance reliability in final assembly.

Resonators Selection Notes

Select this component when a fixed frequency reference near 8.388 MHz is required with minimal external loading components. The integrated capacitor reduces board space and simplifies layout compared to discrete crystal oscillator solutions. Consider the 40 Ohm impedance and ±0.3% accuracy for applications demanding stable timing without active oscillators.

Resonators Part Context

This ceramic resonator belongs to the broader category of passive timing devices used in digital logic circuits. Unlike quartz crystals, it offers a balance between cost, size, and performance suitable for non-critical timing tasks. The SMD321 footprint allows for automated placement in high-volume manufacturing environments requiring consistent electrical characteristics.

Resonators Replacement Considerations

Substitute parts must match the 8.388 MHz frequency, 33 pF internal capacitance, and SMD321 package dimensions. Verify that alternative manufacturers offer comparable ±0.3% tolerance and 40 Ohm ESR specifications to maintain circuit timing integrity.
