Resonators Procurement Notes

Verify the specific package dimensions against your PCB footprint, as this component uses a non-standard SMD outline. Confirm that the ±0.3% frequency tolerance meets your system's phase noise and jitter requirements. Ensure the operating temperature range of -20°C to +80°C aligns with your environmental conditions. Cross-reference the manufacturer datasheet for soldering profile recommendations to prevent thermal damage during reflow processes.

Resonators Selection Notes

Select this resonator when a compact, low-cost alternative to crystal oscillators is needed for fixed-frequency applications. The 2.45 MHz frequency is common in ISM band applications. Consider the ±0.3% tolerance for systems sensitive to frequency drift. The surface-mount form factor is ideal for space-constrained designs. Evaluate the internal impedance match with your oscillator circuit to ensure proper startup and sustained oscillation without additional loading components.

Resonators Part Context

This component belongs to KYOCERA AVX's ceramic resonator family, which offers cost-effective timing solutions compared to quartz crystals. Ceramic resonators utilize piezoelectric ceramic materials to generate mechanical vibrations at specific frequencies. They are widely used in applications where moderate frequency stability is sufficient, such as simple microcontroller clocks or remote control transmitters, providing a balance between performance and manufacturing cost.

Resonators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing oscillator circuits before substituting with other 2.45 MHz ceramic resonators from different manufacturers, as package dimensions and electrical characteristics may vary.
