AWSCR-7.37CPLA-C30-T4

Overview

The AWSCR-7.37CPLA-C30-T4 is a surface-mount ceramic resonator manufactured by Abracon LLC, designed for precise frequency control in electronic circuits. It operates at a nominal frequency of 7.37 MHz with a frequency tolerance of ±0.5% and stability of ±0.3%. The component features an integrated load capacitance of 30 pF and a maximum impedance of 30 Ohms. It supports an operating temperature range from -40°C to +85°C and is housed in a compact 3-SMD non-standard package measuring 6.00mm x 3.00mm x 1.50mm.

Feature Summary

• Integrates built-in capacitors to simplify circuit design
• Provides high frequency stability for reliable timing
• Supports surface mount assembly for automated manufacturing

Applications

• Microcontroller clock sources
• Communication module timing
• Consumer electronics oscillators

Procurement Notes

Verify the specific suffix 'CPLA' against 'CPLB' variants to ensure correct temperature rating compliance. Confirm that the 30 pF internal capacitance matches the target oscillator circuit requirements. Check RoHS3 status and MSL level for handling procedures during procurement and assembly planning.

Selection Notes

Select this component when a cost-effective alternative to quartz crystals is required with moderate stability needs. Ensure the application environment remains within the specified -40°C to +85°C range. Verify that the 30 Ohm impedance is compatible with the driving circuit's gain capabilities to ensure reliable startup.

Part Context

This part belongs to the AWSCR-CPLA series of ceramic resonators from Abracon. It serves as a timing element in systems requiring stable frequencies without the precision of TCXOs or OCXOs. The series is characterized by its integrated capacitor design, reducing external component count.

Replacement Considerations

AWSCR-7.37CPLB-C30-T4 offers extended temperature range up to 125°C.
