AWSCR-27.00CW-T

Overview

The AWSCR-27.00CW-T is a ceramic resonator manufactured by Abracon LLC, designed for surface-mount applications. It operates at a nominal frequency of 27 MHz with a built-in capacitance configuration. The component features a compact 2.5x2.0 mm industrial-grade package and supports IR reflow soldering processes. Key electrical characteristics include a frequency tolerance range of -0.5% to +0.5% and a stability range of -0.2% to +0.2%. This device provides low resonant impedance suitable for cost-sensitive embedded systems requiring precise timing without the complexity of external load capacitors.

Feature Summary

• Built-in capacitance design eliminates the need for external load components
• Low resonant impedance for efficient signal transmission
• Compatible with standard IR reflow soldering processes
• Compact surface-mount package optimized for space-constrained PCB layouts

Applications

• Microcontroller clock sources in embedded systems
• Consumer electronics timing circuits
• Industrial control modules requiring stable frequency references
• Communication devices utilizing 27 MHz carrier frequencies

Procurement Notes

Verify that the specific part number matches the required frequency tolerance and stability specifications for your application. Confirm package dimensions align with your PCB footprint requirements. Ensure compatibility with your manufacturing process, particularly regarding IR reflow capabilities. Check for any recent product lifecycle notifications or discontinuance alerts from the manufacturer before placing orders.

Selection Notes

Select this component when a cost-effective, space-saving timing solution is required without external capacitors. Consider the ±0.5% tolerance if higher precision is needed, as other Abracon series may offer tighter tolerances. Evaluate the operating temperature range against your environmental conditions. Compare against crystal oscillators if lower phase noise or higher stability is critical for your system performance.

Part Context

This ceramic resonator belongs to Abracon's line of passive timing components, distinct from active oscillators like the ASFL1 series. It serves as a simpler alternative to quartz crystals by integrating load capacitance internally. The AWSCR series is widely used in applications where moderate accuracy suffices, offering a balance between performance and manufacturing cost compared to more complex oscillator solutions.

Replacement Considerations

Direct substitutes must match the 27 MHz frequency, 2.5x2.0mm package, and built-in capacitance feature. Verify that replacement parts maintain similar tolerance levels (-0.5% to +0.5%) and stability ranges. Ensure the alternative component supports IR reflow processing. Cross-reference pinout and electrical characteristics to guarantee functional equivalence in the target circuit.
