9C-10.000MAAJ-T

Crystals Overview

The FTS 9C-10.000MAAJ-T is a surface-mount quartz crystal resonator designed for fundamental mode operation within the HC-49/US package. It operates at a nominal frequency of 10 MHz with a frequency tolerance and stability of ±30 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 80 Ohms. It supports an operating temperature range of -20°C to +70°C, making it suitable for standard commercial applications requiring reliable clock source generation.

Crystals Feature Summary

• Surface-mount construction in standard HC-49/US package for direct PCB compatibility
• Fundamental operating mode ensuring stable oscillation characteristics
• RoHS compliant lead-free manufacturing process

Crystals Applications

• PC motherboard clock circuits
• Set-top box timing references
• Display panel synchronization
• Cable modem signal processing

Crystals Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if bulk handling is required. Confirm the manufacturer designation matches FTS specifications rather than generic equivalents. Ensure the HC-49/US footprint aligns with existing board layouts. Cross-reference the 80 Ohm ESR value against circuit requirements to guarantee proper drive level compliance and avoid over-driving the crystal element during assembly validation.

Crystals Selection Notes

Select this component when a standard 10 MHz reference is needed for commercial-grade environments. The 18 pF load capacitance requires matching external capacitors in the oscillator circuit. Consider the -20°C lower limit; industrial applications requiring wider temperature ranges may need alternative series. The fundamental mode operation provides simplicity but limits maximum frequency compared to overtone crystals. Verify drive level sensitivity given the 80 Ohm ESR specification.

Crystals Part Context

This part belongs to the 9C series of surface-mount crystals from FTS/TXC. The series utilizes the HC-49/US form factor adapted for SMD mounting. It serves as a cost-effective solution for mass-produced consumer electronics where space constraints preclude through-hole components but reliability standards remain consistent with traditional crystal performance metrics.

Crystals Replacement Considerations

Direct substitutes include other manufacturers offering HC-49S/SMD packages with identical 10 MHz frequency, 18 pF load capacitance, and ±30 ppm tolerance. Verify ESR values closely match the 80 Ohm specification to maintain oscillator startup reliability. Ensure the replacement part supports fundamental mode operation at this frequency.
