Resonators Procurement Notes

Verify the specific ordering suffix matches the required frequency and tolerance specifications. Confirm that the RoHS compliance status aligns with project requirements. Ensure the tape and reel packaging format is compatible with existing pick-and-place equipment. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit components.

Resonators Selection Notes

Select this component when a precise 4.19 MHz reference is required in space-constrained designs. Consider the absence of internal capacitors when designing the load circuit. Evaluate the thermal performance within the specified -25°C to +85°C range for the target environment. Compare impedance characteristics against other available resonators to ensure optimal oscillator circuit stability.

Resonators Part Context

This part belongs to the ECS-CTA series of ceramic resonators from ECS Inc. International. The series offers various frequency options in a standardized surface-mount package. These components are engineered to replace bulkier crystal oscillators in cost-sensitive applications where moderate stability suffices. The TR suffix indicates tape and reel packaging for high-volume manufacturing.

Resonators Replacement Considerations

Direct substitutes may include other ECS-CTA series variants with matching frequencies or similar ceramic resonators from different manufacturers offering equivalent 30 Ohm impedance and surface-mount dimensions.
