9C-13.560MEEJ-T

Crystals Overview

The 9C-13.560MEEJ-T is a surface-mount MHz crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a nominal frequency of 13.56 MHz with a frequency tolerance and stability of ±10 ppm. The component utilizes an HC-49/US package style, measuring 11.40 mm in length, 4.80 mm in width, and 4.10 mm in maximum height. It features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 30 Ohms. The device supports a base harmonic operating mode and functions within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Provides stable oscillation at the standard RFID frequency of 13.56 MHz
• Utilizes HC-49/US surface-mount packaging for direct PCB integration
• Maintains high frequency accuracy with ±10 ppm tolerance
• Designed for low power consumption with typical drive levels of 100 μW

Crystals Applications

• Radio Frequency Identification (RFID) systems
• Contactless smart card readers
• Consumer electronic devices requiring precise clocking
• Set-top boxes and display modules

Crystals Procurement Notes

Verify the specific ordering suffix to ensure the correct load capacitance and tolerance match the circuit design requirements. Confirm that the HC-49/US footprint aligns with the target printed circuit board layout. Check current lifecycle status as manufacturing schedules may change. Ensure compliance with RoHS3 specifications if required by regional regulations. Validate supply chain authenticity through authorized distributors.

Crystals Selection Notes

Select this component when a standard 13.56 MHz reference is needed for RFID or NFC interfaces. The HC-49/US form factor allows for easy replacement of through-hole crystals in space-constrained designs. Consider the ±10 ppm stability for general-purpose timing where higher precision is not critical. Evaluate the 18 pF load capacitance against the oscillator circuit's input capacitance to ensure proper frequency tuning.

Crystals Part Context

This part belongs to the 9C series of quartz crystals from TXC Corporation, which focuses on cost-effective solutions for mass-market consumer electronics. The series is characterized by standardized dimensions and broad availability of common frequencies. It targets high-volume production environments such as personal computers and cable modems, offering reliable performance across standard commercial temperature ranges.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49/US crystals rated at 13.56 MHz with 18 pF load capacitance and similar ESR values. Verify that alternative parts meet the same ±10 ppm tolerance and operate within the -20°C to +70°C range. Ensure mechanical compatibility with existing PCB footprints.
