7M-12.000MEEC-T

Crystals Overview

The 7M-12.000MEEC-T is a surface-mount quartz crystal manufactured by TXC Corporation, operating at a fundamental frequency of 12 MHz. It features a load capacitance of 9 pF and an equivalent series resistance (ESR) of 80 Ohms. The component provides a frequency stability of ±10 ppm across the specified temperature range of -20°C to +70°C. Housed in a compact 4-SMD, no-lead package with dimensions of 3.20 mm x 2.50 mm, it supports base harmonic operation mode.

Crystals Feature Summary

• Delivers high frequency stability of ±10 ppm within the industrial temperature range.
• Utilizes a low-profile 4-SMD no-lead surface mount package for automated assembly.
• Operates in fundamental base harmonic mode for precise timing applications.

Crystals Applications

• Industrial control systems requiring stable clock signals
• Consumer electronics with space-constrained PCB layouts
• Automotive infotainment and instrumentation modules

Crystals Procurement Notes

Verify the specific suffix 'EC' confirms the 9 pF load capacitance and 80 Ohm ESR parameters against the official datasheet before procurement. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Confirm RoHS compliance status and moisture sensitivity level ratings match project specifications.

Crystals Selection Notes

Select this component when a 12 MHz reference with tight ±10 ppm stability is required for -20°C to +70°C environments. Compare the 80 Ohm ESR against circuit design limits to ensure proper oscillator startup. Consider the 3.2x2.5 mm footprint compatibility with existing board designs versus alternative packages like the 7M-12.000MAAE-T which offers different electrical characteristics.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation, designed for general-purpose timing applications. It complements other variants in the lineup such as the 7M-12.000MAAE-T and 7M-12.000MEEQ-T, offering distinct load capacitance and ESR values to suit various oscillator circuit topologies and performance requirements.

Crystals Replacement Considerations

The 7M-12.000MAHE-T is listed as a parameter-equivalent substitute by the manufacturer. Other similar options include EPSON FA-238V series crystals, though these may differ in physical dimensions or electrical parameters. Verify pinout and mounting compatibility before substitution.
