7M-16.000MEEC-T

Crystals Overview

The 7M-16.000MEEC-T is a surface-mount quartz crystal manufactured by TXC Corporation, operating at a fundamental frequency of 16 MHz. It features a frequency tolerance and stability of ±10 ppm, with a load capacitance of 9 pF and an equivalent series resistance (ESR) of 80 Ohms. The component utilizes a 4-SMD, no-lead package with dimensions of 3.20 mm x 2.50 mm and a maximum height of 0.80 mm. Designed for base harmonic operation, it supports an extended industrial temperature range from -40°C to +85°C and complies with RoHS3 standards.

Crystals Feature Summary

• High frequency stability with ±10 ppm tolerance and stability specifications
• Compact 4-SMD no-lead surface mount package design
• Extended industrial temperature range capability from -40°C to +85°C
• Compliance with RoHS3 environmental regulations

Crystals Applications

• General-purpose clock signal generation in electronic circuits
• Timing reference sources for microcontrollers and processors
• Communication equipment requiring stable frequency references
• Industrial control systems operating in varied thermal environments

Crystals Procurement Notes

Verify the specific suffix 'EC' against official datasheets to confirm the 9pF load capacitance and 80 Ohm ESR parameters, as these differ from other variants in the 7M series. Confirm that the required ±10 ppm stability meets the system timing requirements before procurement. Ensure the 4-SMD footprint matches the PCB layout constraints.

Crystals Selection Notes

Select this component when precise ±10 ppm frequency stability is required compared to standard ±30 ppm alternatives. The 9pF load capacitance necessitates matching circuit design, differing from common 12pF or 20pF crystals. Consider the 80 Ohm ESR value for oscillator circuit drive level calculations to ensure reliable startup and operation within the specified temperature range.

Crystals Part Context

This part belongs to the 7M Series of ceramic quartz crystals from TXC Corporation. The series offers various frequency options and package sizes, with the 7M-16.000MEEC-T representing a high-stability variant optimized for applications demanding tighter frequency control than standard commercial grade crystals provide.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative crystals such as those from Aker Technology Corp only if electrical parameters including load capacitance, ESR, and stability are strictly matched.
