Resonators Procurement Notes

Verify the specific suffix 'R0' corresponds to the required tape and reel packaging format. Confirm that the 4.23 MHz frequency aligns with the target system requirements. Ensure the ±0.5% tolerance meets the design specifications. Check compatibility with the intended operating temperature range of -20°C to +80°C before finalizing procurement.

Resonators Selection Notes

Select this component when a precise 4.23 MHz reference is needed without external capacitors. The 15 pF internal load capacitance simplifies layout compared to discrete crystals. Consider the ±0.5% tolerance for applications requiring moderate frequency accuracy. The SMD form factor is suitable for automated assembly processes in compact electronic designs.
