7A-14.7456MAAJ-T

Crystals Overview

The TXC Corporation 7A-14.7456MAAJ-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 14.7456 MHz. It features a frequency tolerance and stability of ±30 ppm across the specified temperature range. The component utilizes a 18 pF load capacitance and exhibits an equivalent series resistance (ESR) of 50 Ohms. Designed for SMD/SMT installation, it is housed in a compact 2-SMD, No Lead package with dimensions of 5.0 mm x 3.2 mm. The device supports a drive level ranging from 1 to 200 μW, with a typical value of 100 μW.

Crystals Feature Summary

• Glass-sealed construction provides enhanced resistance to moisture and environmental stress compared to standard ceramic or resin packages.
• Fundamental mode operation ensures stable oscillation characteristics suitable for precise timing applications.
• RoHS compliant manufacturing process, with lead content in the glass seal falling under specific regulatory exemptions.

Crystals Applications

• Portable USB data acquisition cards
• NFC reader devices
• Small-sized IoT modules

Crystals Procurement Notes

Verify the specific suffix 'J' against the manufacturer's official part number guide to confirm the exact load capacitance and pin configuration. Ensure the design-in phase accounts for the 2-SMD footprint dimensions. Confirm RoHS exemption status if required by specific regional compliance standards before final procurement.

Crystals Selection Notes

Select this component when a 14.7456 MHz fundamental frequency is required with ±30 ppm stability. The 18 pF load capacitance matches standard MCU inputs without external adjustment. The glass-sealed variant is preferred over ceramic packages for applications requiring higher reliability during reflow soldering and thermal cycling.

Crystals Part Context

This part belongs to the TXC 7A series of surface-mount crystals. The series is characterized by its 5.0x3.2 mm footprint and glass-sealing technology. This specific model represents a standard frequency point within the series, offering a balance between performance and cost for consumer and industrial electronics.

Crystals Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires matching the 14.7456 MHz frequency, 18 pF load capacitance, 50 Ohm ESR, and 5.0x3.2 mm package dimensions.
