Resonators Procurement Notes

Verify that the specific part number matches the required frequency and tolerance specifications before procurement. Confirm that the surface-mount footprint dimensions align with the target PCB design. Ensure the operating temperature range meets the environmental requirements of the final application. Check for compliance with relevant regulatory standards such as REACH status.

Resonators Selection Notes

Select this component when a cost-effective, low-profile timing solution is required for digital circuits. The built-in capacitor feature reduces component count and assembly complexity compared to crystal oscillators requiring external loads. Consider the ±0.5% tolerance for applications where high precision is not critical. Evaluate the thermal performance within the specified -20°C to +80°C range against operational conditions.

Resonators Part Context

This component belongs to the ECS HFR series of surface-mount ceramic resonators. The series offers various frequency options in standardized packages. The HFR-20.00-B-TR variant specifically targets 20 MHz applications. It serves as an alternative to traditional quartz crystals in consumer electronics and industrial control systems where moderate frequency accuracy suffices.

Resonators Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 8 pF load capacitance, and similar physical dimensions. Verify compatibility with existing PCB footprints and circuit designs when considering cross-brand alternatives.
