AS-13.560MAHE-B

Crystals Overview

The AS-13.560MAHE-B is a 13.56 MHz fundamental mode crystal resonator manufactured by TXC Corporation, designed for surface-mount applications in the HC-49/US package. It features a nominal load capacitance of 12 pF and offers frequency tolerances of ±30 ppm at 25°C with a stability of ±30 ppm across the industrial temperature range of -40°C to +85°C. The component operates in basic frequency mode with an equivalent series resistance (ESR) typically not exceeding 100 ohms, ensuring reliable oscillation. It is RoHS compliant and suitable for high-volume production environments requiring standard industrial-grade timing solutions.

Crystals Procurement Notes

Verify the specific suffix version when ordering, as engineering samples (S-series) differ from mass production units (A-series). Confirm package compatibility with existing PCB footprints despite the HC-49/US designation. Check current lifecycle status as some variants may be obsolete or subject to discontinuation notices. Ensure supply chain partners can provide genuine TXC Corporation components to avoid counterfeit risks.

Crystals Selection Notes

Select this component for applications requiring robust industrial temperature performance and standard 12 pF load capacitance matching. Consider the ESR limits for oscillator circuit design to ensure start-up reliability. Evaluate the physical dimensions against board space constraints despite the traditional package style. Compare frequency stability requirements against the ±30 ppm specification to determine if tighter tolerances are necessary for long-term drift management.

Crystals Part Context

This crystal belongs to TXC's standard industrial crystal lineup, targeting cost-effective yet reliable timing solutions for mass-market electronics. The HC-49/US form factor allows for versatile mounting options while maintaining electrical performance standards. It serves as a foundational component for wireless communication subsystems operating at the ISM band frequency of 13.56 MHz.

Crystals Replacement Considerations

Direct substitutes include other 13.56 MHz crystals with identical 12 pF load capacitance and HC-49/US packaging. Verify that alternative parts meet the same -40°C to +85°C temperature range and ±30 ppm stability requirements. Cross-reference ESR values to ensure circuit compatibility without redesign.
