AWSCR-20.00MSA-T

Overview

The AWSCR-20.00MSA-T is a ceramic resonator manufactured by Abracon LLC, designed for surface-mount applications. It operates at a nominal frequency of 20 MHz with a frequency tolerance of ±0.5% and stability of ±0.7%. The component features a built-in capacitance of 15 pF and an impedance of 60 Ohms. It is housed in a compact 3-SMD package measuring 2.5 mm in length, 2.0 mm in width, and 1.0 mm in height. The device supports a wide operating temperature range from -40°C to +125°C, ensuring reliability in industrial environments.

Feature Summary

• Integrated internal capacitors eliminate the need for external load capacitors, simplifying circuit design.
• Compact surface-mount package facilitates automated assembly and space-constrained layouts.
• Wide operating temperature range ensures stable performance across industrial conditions.

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 15 pF built-in capacitance matches the target oscillator circuit requirements. Ensure the PCB footprint aligns with the 2.5x2.0 mm dimensions. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a cost-effective, small-footprint clock source is needed for microcontrollers or simple logic circuits. The built-in capacitor reduces BOM count compared to discrete crystal solutions. Consider the ±0.7% stability limit; it may not suit high-precision applications requiring tighter tolerances. Compare against the AWSCR-CPLB series if higher stability or different impedance values are required.

Part Context

This part belongs to the Abracon AWSCR-MSA series of ceramic resonators. These components serve as alternatives to quartz crystals in applications where moderate accuracy suffices. The MSA series is characterized by its low profile and integrated capacitance, distinguishing it from standard two-pin ceramic resonators.

Replacement Considerations

Direct substitutes include other Abracon AWSCR-20.00 variants with matching 15 pF capacitance and similar impedance. Cross-reference with competitor ceramic resonators offering identical 20 MHz frequency and SMD footprint compatibility. Verify that replacement parts support the same -40°C to +125°C temperature range.
