7M-13.560MEIJ-T

Crystals Overview

The TXC Corporation 7M-13.560MEIJ-T is a surface-mount MHz quartz crystal oscillator designed for precision timing applications. It operates at a nominal frequency of 13.56 MHz with a tolerance of ±10 ppm at 25°C and ±20 ppm over the extended temperature range of -40°C to +85°C. The component features an 18 pF load capacitance and an equivalent series resistance (ESR) of 80 Ohms. Housed in a compact 3.2 mm x 2.5 mm seam seal package, it utilizes a four-pad no-lead SMD configuration suitable for automated assembly processes.

Crystals Feature Summary

• Seam seal construction provides robust environmental protection and mechanical stability for the quartz element.
• Compact 3.2 mm x 2.5 mm footprint enables efficient board space utilization in dense electronic designs.
• Four-pad no-lead surface mount design facilitates reliable soldering and high-volume manufacturing integration.

Crystals Applications

• RFID reader and writer circuitry
• Wireless communication modules requiring 13.56 MHz carrier frequencies
• Smart card and NFC interface systems

Crystals Procurement Notes

Verify the specific suffix 'MEIJ' against the manufacturer's current datasheet to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with reflow soldering profiles defined for seam seal packages. Cross-reference RoHS compliance status with the latest regulatory documentation prior to final procurement decisions.

Crystals Selection Notes

Select this component when a stable 13.56 MHz reference is required for RFID or NFC applications. The ±10 ppm initial tolerance suits most standard communication protocols. Consider the 80 Ohm ESR value to ensure proper oscillator circuit matching. The wide operating temperature range supports industrial and consumer electronics environments.

Crystals Part Context

This part belongs to the TXC 7M series of seam seal crystals, which are engineered for high-frequency stability in small form factors. The series is widely utilized in wireless data transmission devices where precise frequency control is critical for signal integrity and protocol compliance.

Crystals Replacement Considerations

Direct substitutes include the 7M-13.560MAHK-T and 7M-13.560MDHJ-T from the same manufacturer. Verify that alternative parts match the 13.56 MHz frequency, 18 pF load capacitance, and identical 3.2x2.5 mm package dimensions before implementation.
