AWSCR-48.00CW-T

Overview

The AWSCR-48.00CW-T is a surface-mount ceramic resonator manufactured by Abracon LLC, designed for precision frequency control in electronic circuits. It operates at a nominal frequency of 48 MHz with a tight frequency tolerance of ±0.2%. The component features an integrated load capacitance of 5 pF and exhibits a series resistance of 50 Ohms. It is rated for operation within a temperature range of -25°C to +85°C. Packaged in a standard SMD form factor, this resonator provides stable oscillation for microcontrollers and communication modules requiring accurate timing signals.

Feature Summary

• Integrated internal capacitor eliminates external tuning components
• High frequency stability with ±0.2% tolerance
• Surface mount design for automated assembly

Applications

• Microcontroller clock sources
• Communication module timing
• Embedded system oscillators

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration when ordering. Confirm that the 5 pF built-in capacitance matches the target circuit's load requirements. Ensure the operating temperature range of -25°C to +85°C aligns with the environmental conditions of the final application. Cross-reference the manufacturer part number against distributor catalogs to ensure availability and correct revision status.

Selection Notes

Select this component when a compact, cost-effective solution with high accuracy is required for 48 MHz applications. The integrated capacitor simplifies PCB layout compared to discrete crystal setups. Consider the 50 Ohm impedance for driver compatibility. This resonator is suitable for consumer electronics and industrial controls where moderate temperature stability suffices.

Part Context

This part belongs to Abracon's AWSCR-CW series of ceramic resonators. These components are engineered as alternatives to quartz crystals, offering easier soldering profiles and lower sensitivity to mechanical stress. The CW series specifically denotes the package style and capacitance configuration, widely used in mass-produced digital devices.

Replacement Considerations

Direct substitutes include other 48 MHz ceramic resonators with 5 pF internal capacitance and similar tolerance ratings from manufacturers like Murata or ECS. Verify pinout compatibility and physical footprint dimensions before substitution.
