7M-13.560MEEE-T

Crystals Overview

The TXC CORPORATION 7M-13.560MEEE-T is a fundamental mode quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 13.56 MHz with a frequency tolerance and stability of ±10 ppm. The component features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 80 Ohms. It utilizes a 4-SMD, No Lead package with dimensions of 3.20 mm x 2.50 mm and a maximum height of 0.7 mm. This device supports base harmonic operation and is suitable for precision timing circuits requiring tight frequency control.

Crystals Feature Summary

• Provides high frequency stability with ±10 ppm tolerance for precise timing applications
• Utilizes a compact 4-SMD no-lead surface mount package for automated assembly
• Operates in fundamental mode to ensure stable oscillation characteristics

Crystals Applications

• RFID reader and writer clock sources
• Wireless communication module timing references
• Precision microcontroller oscillator circuits

Crystals Procurement Notes

Verify the specific suffix EEEJ against official datasheets to confirm the exact electrical parameters, particularly the 12pF load capacitance and 80 Ohm ESR. Ensure compatibility with the target circuit's load capacitance requirements. Confirm RoHS3 compliance status through the manufacturer's latest documentation before integration into production designs.

Crystals Selection Notes

Select this component when a 13.56 MHz frequency is required with tighter than standard ±30 ppm stability. The 12pF load capacitance must match the oscillator circuit design. Consider the 80 Ohm ESR value for drive level sensitivity. The small 3.2x2.5mm footprint is ideal for space-constrained PCB layouts compared to larger 5x3.2mm alternatives.

Crystals Part Context

This part belongs to the TXC 7M series of MHz crystals, which are characterized by their small SMD form factor. The series offers various frequency options and tolerance levels. The 7M-13.560MEEE-T specifically targets applications needing higher accuracy than the standard ±30 ppm variants, such as those found in NFC and RFID systems operating at the ISM band frequency.

Crystals Replacement Considerations

Public confirmed substitute: 7M-13.560MAAE-T. Note that the MA variant typically specifies a 12pF load capacitance but may differ in ESR (100 Ohms vs 80 Ohms) and physical dimensions (3.2x2.5mm vs potential variations). Verify all electrical parameters against the schematic requirements before substitution.
