Resonators Overview

The ECS-SR1-4.19-A-TR is a surface mount ceramic resonator manufactured by ECS Inc. It operates at a nominal frequency of 4.19 MHz with a frequency stability of ±0.3% and a tolerance of ±0.5%. The component features an impedance of 40 Ohms and includes a built-in capacitor for simplified circuit design. It is housed in a non-standard 3-SMD package with a height of 0.071 inches (1.80 mm). The device supports an operating temperature range from -20°C to 80°C and complies with RoHS standards.

Resonators Feature Summary

• Integrated built-in capacitor eliminates external components
• Surface mount construction for automated assembly
• Lead-free manufacturing process compliant with environmental standards

Resonators Applications

• Commercial electronic applications requiring precise timing
• Microcontroller clock sources
• Simple oscillator circuits

Resonators Procurement Notes

Verify the specific ordering suffix to confirm package dimensions and lead-free status. Confirm that the application environment remains within the specified -20°C to 80°C operating range. Check current lifecycle status as the part may be subject to obsolescence. Ensure compatibility with existing PCB footprints for 3-SMD non-standard packages before procurement.

Resonators Selection Notes

Select this component when a cost-effective, compact timing solution is required for commercial-grade electronics. The integrated capacitor simplifies layout compared to discrete crystal oscillators. Consider the ±0.5% tolerance if higher precision is not critical. Verify that the 4.19 MHz frequency aligns with system requirements and that the surface mount form factor fits the mechanical constraints.

Resonators Part Context

This part belongs to the ECS SR1 series of ceramic resonators designed for surface mount technology. The series offers a balance between performance and cost for consumer and commercial devices. The SR1 series typically utilizes piezoelectric ceramic materials to provide stable frequency generation in space-constrained designs.

Resonators Replacement Considerations

Direct substitutes include other 4.19 MHz ceramic resonators from different manufacturers with compatible SMD footprints. Cross-reference the impedance and capacitance values to ensure circuit compatibility. Verify that alternative parts meet the same temperature and tolerance specifications.
