• Supports surface mount assembly for automated production

Applications

• Microprocessor clock generation
• Consumer electronic control boards
• General-purpose timing circuits

Procurement Notes

Verify the specific datasheet version for the SMR-10.000-B to confirm exact dimensional tolerances and soldering profile requirements. Ensure that the application circuit matches the 50 Ohm ESR specification. Confirm compliance with RoHS directives if required by the final product regulations. Cross-reference the package dimensions against the PCB footprint library before finalizing the design.

Selection Notes

Select this component when a cost-effective, low-profile timing solution is required for non-critical clock applications. It is suitable for general-purpose microcontrollers where high precision is not mandatory. Consider the ±0.3% stability limit for system timing budgets. Evaluate the -20°C to +80°C range against the environmental conditions of the target device.

Part Context

This part belongs to Raltron Electronics' line of ceramic resonators, which serve as alternatives to quartz crystals in cost-sensitive designs. Ceramic resonators typically offer lower Q-factors but provide adequate stability for many digital logic applications. This specific model targets the mass-market consumer electronics segment.

Replacement Considerations

Direct substitutes include other 10 MHz ceramic resonators with similar ESR and package dimensions. Verify compatibility with existing oscillator circuits, as ceramic resonators may require different load capacitance values compared to quartz crystals.
