7M-12.000MEEQ-T

Crystals Overview

The 7M-12.000MEEQ-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation, designed for precision frequency control in electronic circuits. It operates at a nominal frequency of 12 MHz with a frequency tolerance of ±10 ppm. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 100 Ohms. It utilizes a four-terminal SMD package without leads, measuring 3.2 x 2.5 mm, suitable for automated assembly processes.

Crystals Feature Summary

• Four-terminal surface-mount design for enhanced stability
• High precision frequency control with ±10 ppm tolerance
• Seam-sealed construction for environmental protection

Crystals Applications

• Precision timing circuits requiring stable clock signals
• Communication systems utilizing 12 MHz reference frequencies
• Embedded microcontroller clock sources

Crystals Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the four-terminal SMD package aligns with the target PCB footprint and soldering profile. Check manufacturer documentation for recommended reflow temperature curves to prevent mechanical stress during assembly. Ensure storage conditions meet moisture sensitivity level requirements prior to placement.

Crystals Selection Notes

Select this component when a 12 MHz reference with ±10 ppm accuracy is required in a compact form factor. The 10 pF load capacitance must match the oscillator circuit design to achieve specified frequency stability. Consider the 100 Ohm ESR value for driver strength limitations within the host circuit. The four-terminal configuration offers superior performance compared to two-terminal variants in high-vibration environments.

Crystals Part Context

This part belongs to the 7M series of miniature surface-mount crystals from TXC Corporation. The series is characterized by small dimensions and high reliability for consumer and industrial electronics. The 7M-12.000MEEQ-T specifically denotes the 12 MHz variant with seam sealing and four-terminal construction, distinguishing it from standard two-terminal SMD crystals.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz, 10 pF, ±10 ppm four-terminal SMD crystals from manufacturers such as Epson or NDK. Verify that replacement parts maintain identical dimensional constraints and terminal configurations to ensure board compatibility.
