Packaged in a compact 3-SMD non-standard footprint measuring 6.00mm x 3.00mm x 1.80mm, it supports standard SMT assembly processes.

Feature Summary

• Integrates internal matching capacitors to eliminate the need for external discrete components
• Provides stable clock signals with high frequency accuracy for microcontroller systems
• Supports industrial-grade operation across wide temperature extremes

Applications

• Microcontroller clock sources in consumer electronics
• Timing circuits for remote control devices
• General-purpose digital logic timing references

Procurement Notes

Verify that the specific part number matches the required frequency, capacitance, and impedance specifications before integration. Confirm compliance with RoHS directives and REACH regulations for the target market. Ensure PCB layout adheres to the recommended pad dimensions for the 3-SMD package to guarantee proper soldering and mechanical stability during reflow processes.

Selection Notes

Select this component when a cost-effective, space-saving solution is needed for low-to-medium precision timing applications. It serves as a direct replacement for quartz crystals requiring external load capacitors, reducing bill-of-materials complexity. Suitable for designs where ±0.5% frequency tolerance is acceptable and operating temperatures fall within the specified industrial range.

Part Context

This component belongs to the AWSCR-CPLB series of ceramic resonators from Abracon LLC. The series is characterized by its built-in capacitor architecture, which simplifies design and improves reliability compared to traditional crystal oscillator setups. These devices are widely used in general-purpose electronics where moderate frequency stability is sufficient.

Replacement Considerations

AWSCR-4.00CPLA-C30-T4 (Note: Verify impedance differences; CPLA typically specifies 100 Ohms while CPLB specifies 30 Ohms). Cross-referencing requires confirmation of circuit drive level compatibility due to impedance variations.
