• Surface mount construction optimized for high-volume manufacturing
• Operational stability across standard commercial temperature ranges

Resonators Applications

• Microcontroller clock sources
• Simple timing circuits
• Consumer electronics assemblies

Resonators Procurement Notes

Verify the specific frequency tolerance requirement against the datasheet specification of ±0.5%. Confirm that the 30 pF built-in capacitance aligns with the target oscillator circuit design parameters. Ensure the operating temperature range of -20°C to +80°C meets the environmental conditions of the final application. Check the 3-SMD non-standard package dimensions for PCB footprint compatibility before integration.

Resonators Selection Notes

Select this component when a cost-effective timing solution is required without the complexity of discrete capacitors. The integrated capacitor feature reduces board space and assembly steps compared to traditional crystal setups. Consider the ±0.5% tolerance for applications where moderate frequency accuracy is sufficient. Evaluate the surface mount form factor against available PCB real estate constraints.

Resonators Part Context

This part belongs to the ECS-SR1-B series of SMD ceramic resonators. The series is characterized by the inclusion of built-in capacitors, distinguishing it from bare crystals. These components serve as alternatives to quartz crystals in applications prioritizing simplicity and lower cost over high precision. The manufacturer offers various frequencies within this series to support diverse timing needs.

Resonators Replacement Considerations

Direct substitutes include other ECS SR1 series parts with matching frequency and package dimensions. Cross-reference mechanical footprints carefully due to the non-standard 3-SMD case type. Verify equivalent electrical characteristics such as load capacitance and tolerance if sourcing from different manufacturers.
