7V-14.7456MAAQ-T

Crystals Overview

The 7V-14.7456MAAQ-T is a fundamental mode MHz crystal manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 14.7456 MHz with a frequency stability and tolerance of ±30 ppm. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 100 Ohms. It utilizes a 4-SMD, No Lead package with dimensions of 3.20 mm in length, 2.50 mm in width, and a maximum height of 0.90 mm. The device supports soldering via SMD/SMT installation methods.

Crystals Feature Summary

• Fundamental oscillation mode operation for stable frequency generation
• Compact 4-SMD no-lead package suitable for space-constrained designs
• Standard 10 pF load capacitance configuration for common circuit integration

Crystals Applications

• General-purpose clock signal generation in electronic circuits
• Timing reference sources for microcontroller systems
• Synchronization components in communication interfaces

Crystals Procurement Notes

Verify the specific suffix 'AAQ' against official TXC documentation to confirm the 10 pF load capacitance specification, as variations exist within the 7V series. Ensure the selected variant matches the required ESR and frequency tolerance for the target application. Confirm RoHS compliance status through current manufacturer declarations prior to final procurement decisions.

Crystals Selection Notes

Select this component when a 14.7456 MHz fundamental crystal with ±30 ppm stability is required. The 10 pF load capacitance must align with the oscillator circuit design parameters. Consider the 100 Ohm ESR value for drive level sensitivity. The 3.2mm x 2.5mm footprint dictates PCB layout constraints compared to larger packages like HC-49.

Crystals Part Context

This part belongs to the 7V series of ceramic crystals from TXC Corporation. The series offers various load capacitance options, including 8 pF, 10 pF, 12 pF, and 18 pF variants distinguished by their model suffixes. The 7V series provides a compact alternative to traditional through-hole crystals while maintaining standard electrical characteristics for fundamental mode applications.

Crystals Replacement Considerations

Direct substitutes include other 7V series parts with matching frequencies but different load capacitances, such as 7V-14.7456MAAE-T (12 pF) or 7V-14.7456MAAV-T (8 pF), provided the circuit can accommodate the capacitance change. Cross-manufacturer replacements require verification of ESR, size, and stability specifications.
