9C-6.500MAAJ-T

Crystals Overview

The TXC Corporation 9C-6.500MAAJ-T is a surface-mount quartz crystal resonator operating at a nominal frequency of 6.5 MHz. It utilizes the HC-49/US package with dimensions of 11.4 mm in length, 4.8 mm in width, and 3.8 mm in height. The component features a load capacitance of 18 pF and a maximum series resistance (ESR) of 80 Ohms. Frequency tolerance is specified at ±30 ppm, with a frequency stability of 0.003%. The drive level is rated at 1 µW, and the aging rate is 5 ppm per year. It operates within a temperature range of -20°C to +70°C.

Crystals Feature Summary

Crystals Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if bulk procurement is required. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the operating temperature range meets the final application environment requirements.

Crystals Selection Notes

Select this component when a standard 6.5 MHz reference is needed in an HC-49/US form factor. Consider the ±30 ppm tolerance against system clock accuracy requirements. Verify that the 1 µW drive level is sufficient for the target oscillator circuit input impedance.

Crystals Part Context

This part belongs to the TXC 9C series of miniature crystals. The series is characterized by high reliability and cost-effectiveness for mass-produced consumer devices. The HC-49/US package allows for easy transition from through-hole designs without significant PCB layout modifications.

Crystals Replacement Considerations

Direct substitutes include other manufacturers offering HC-49/US SMD crystals with identical 6.5 MHz frequency, 18 pF load capacitance, and similar ESR specifications. Verify mechanical compatibility before substitution.
