AWSCR-7.37CPLB-C30-T4

Overview

The AWSCR-7.37CPLB-C30-T4 is a surface-mount ceramic resonator from the Abracon AWSCR-CPLB series, 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 ±0.4%. The component features an integrated load capacitance of 30 pF and a motional resistance of 30 Ohms. It is housed in a compact 3-SMD package measuring 6.00mm x 3.00mm x 1.50mm. The device supports a wide operating temperature range from -40°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Integrated 30 pF load capacitance eliminates external capacitor requirements
• High frequency stability of ±0.4% ensures reliable timing performance
• Wide industrial temperature rating from -40°C to +125°C
• Compact 3-pin SMD footprint suitable for space-constrained designs

Applications

• Microcontroller clock sources
• Communication module timing references
• Industrial control system oscillators
• Consumer electronics timing circuits

Procurement Notes

Verify the specific suffix C30-T4 confirms the 30 pF internal capacitance and tape-and-reel packaging configuration. Ensure the design accommodates the 3-SMD non-standard package dimensions of 6.00mm x 3.00mm x 1.50mm. Confirm that the application circuit matches the specified 30 Ohm motional resistance for optimal oscillator startup. Check for RoHS3 compliance requirements if applicable to the final product regulations.

Selection Notes

Select this component when a stable 7.37 MHz reference is required without external capacitors. The ±0.4% stability offers better precision than standard ceramic resonators. The wide temperature range makes it suitable for harsh environments. Compare against the CPLA series if lower temperature operation (-40°C to 85°C) suffices, noting the CPLB variant provides extended thermal capability.

Part Context

This part belongs to the Abracon AWSCR-CPLB series of ceramic resonators. These components are designed as cost-effective alternatives to quartz crystals, offering easier soldering profiles and higher vibration resistance. The series utilizes a monolithic ceramic construction to provide frequency stability in compact surface-mount packages for various consumer and industrial applications.

Replacement Considerations
