AWSCR-4.91CPLA-C30-T4

Overview

The AWSCR-4.91CPLA-C30-T4 is a surface-mount ceramic resonator from Abracon LLC, designed for industrial applications. It operates at a nominal frequency of 4.91 MHz with a frequency tolerance of ±0.5% and stability of ±0.3%. The component features built-in load capacitors of 30 pF and a resonant impedance of 30 Ohms. It supports an operating temperature range of -40°C to +85°C and is housed in a compact 6.00mm x 3.00mm x 1.50mm 3-SMD package.

Feature Summary

• Integrates built-in 30 pF capacitors to simplify circuit design
• Features low resonant impedance suitable for IR reflow soldering processes
• Provides stable frequency generation within specified industrial temperature ranges

Applications

• Industrial control systems requiring precise timing
• Microcontroller clock sources in harsh environments
• Communication modules needing stable carrier frequencies

Procurement Notes

Verify the specific suffix 'T4' corresponds to the tape and reel packaging configuration required for automated assembly lines. Confirm that the 30 Ohm impedance matches the driving circuit requirements of the target microcontroller or logic family. Ensure the -40°C to 85°C temperature rating aligns with the operational environment specifications of the final product application.

Selection Notes

Select this component when a cost-effective, miniature timing solution is needed for industrial-grade electronics. The integrated capacitor eliminates external components, reducing board space and assembly complexity. Choose this model over standard crystals if lower Q-factor and higher shock resistance are prioritized over ultra-high precision stability.

Part Context

This part belongs to the AWSCR-CPLA series of industrial grade ceramic resonators. These components are RoHS compliant and REACH affected. They serve as alternatives to traditional quartz crystals in applications where moderate accuracy is sufficient and size constraints are critical.

Replacement Considerations

AWSCR-7.37CPLB-C30-T4 (Different frequency), AWSCR-10.00CPLA-C30-T4 (Different frequency), AWSCR-4.19CPLA-C30-T4 (Different frequency). Substitutes must match the 4.91 MHz frequency and 30 pF capacitance exactly.
