Resonators Procurement Notes

Verify the specific suffix 'A' against official ECS documentation to confirm tolerance and capacitance values. Ensure the ordering part number matches the required frequency stability specifications. Cross-reference the datasheet for pinout compatibility and recommended soldering profiles to prevent thermal damage during assembly.

Resonators Selection Notes

Select this component when a cost-effective, low-profile timing solution is required for microcontroller-based designs. The built-in capacitor feature reduces external component count compared to standard crystals. Consider the ±0.4% stability requirement relative to system timing accuracy needs before finalizing the design.

Resonators Part Context

This part belongs to the ECS HFR series of ceramic resonators, which are widely used as alternatives to quartz crystals in applications where moderate stability suffices. The series offers various frequencies and packages, providing designers with flexible options for integrating timing functions into PCB layouts without complex oscillator circuits.

Resonators Replacement Considerations

Direct substitutes include other 20 MHz ceramic resonators in similar SMD packages from manufacturers like Murata or TXC. Verify that replacement parts maintain equivalent built-in capacitance and frequency tolerance to ensure circuit compatibility.
