AS-10.000MAHI-B

Crystals Overview

The FTS AS-10.000MAHI-B is a fundamental frequency quartz crystal resonator designed for precision timing applications. Operating at a nominal frequency of 10 MHz, this component provides a frequency stability of ±30 ppm to ensure accurate clock signals in electronic circuits. It features a load capacitance of 16 pF and an equivalent series resistance (ESR) of 80 Ohms, which are critical parameters for oscillator circuit design and impedance matching. The device is housed in a standard HC-49S package, measuring 11.50 mm in length and 5.00 mm in width, facilitating easy integration into through-hole PCB layouts. This crystal is AEC-Q200 qualified, indicating its suitability for automotive electronics environments where reliability under varying thermal conditions is required.

Crystals Feature Summary

• AEC-Q200 qualified for automotive grade reliability standards
• Fundamental mode operation for stable 10 MHz signal generation
• HC-49S package format for standard through-hole mounting

Crystals Applications

• Automotive electronic control units requiring precise clock synchronization
• Microcontroller base clock sources for embedded systems
• Communication interface modules needing stable frequency references

Crystals Procurement Notes

Verify the specific manufacturer designation on the datasheet, as some listings incorrectly associate this part number with Texas Instruments while others identify FTS as the producer. Confirm that the HC-49S package dimensions match your board space requirements. Ensure the 16 pF load capacitance aligns with your oscillator circuit design to maintain the specified ±30 ppm stability. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Crystals Selection Notes

Select this component when a 10 MHz reference with ±30 ppm stability is required for automotive or industrial applications. The HC-49S package is suitable for manual assembly or standard wave soldering processes. Consider the 80 Ohm ESR value when designing the oscillator feedback network to ensure proper startup and sustained oscillation. The AEC-Q200 qualification makes it appropriate for harsh environment deployments where long-term frequency drift must be minimized compared to commercial grade crystals.

Crystals Part Context

This crystal belongs to the AS series from FTS, which focuses on fundamental frequency resonators. The AS-10.000MAHI-B variant specifically targets the 10 MHz market segment, a common frequency for microprocessors and communication protocols. Its inclusion in the AEC-Q200 qualified list distinguishes it from general-purpose commercial crystals, offering higher robustness against temperature variations and mechanical stress typical in vehicle interiors.

Crystals Replacement Considerations

Direct substitutes must match the 10 MHz frequency, HC-49S package, 16 pF load capacitance, and ±30 ppm stability. Verify AEC-Q200 qualification if automotive use is intended. Cross-reference ESR values near 80 Ohms to prevent oscillator startup failures.
