7V-26.000MAAQ-T

Crystals Overview

The 7V-26.000MAAQ-T is a fundamental mode quartz crystal manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 26 MHz with a load capacitance of 10 pF and a frequency tolerance of ±30 ppm. The component features an equivalent series resistance (ESR) of 60 Ohms and is housed in a compact 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm x 0.90 mm. It supports a standard operating temperature range from -20°C to +70°C.

Crystals Feature Summary

• Fundamental mode quartz crystal operation
• Compact 4-SMD surface-mount package
• Standard commercial temperature range support

Crystals Applications

• General-purpose timing circuits
• Microcontroller clock sources
• Consumer electronics systems

Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as this unit is specified for 10 pF. Confirm that the ±30 ppm frequency tolerance aligns with system stability needs. Ensure the -20°C to +70°C operating range covers the intended environmental conditions. Cross-reference the 60 Ohm ESR value with oscillator driver strength specifications to prevent over-driving or failure.

Crystals Selection Notes

Select this component when a 26 MHz reference is required in a small form factor. Compare against other 7V series variants if different load capacitances, such as 8 pF or 12 pF, are needed. Consider the AV series if automotive qualification (AEC-Q200) or wider temperature ranges are necessary. Verify package dimensions match the PCB footprint exactly.

Crystals Part Context

This part belongs to the TXC 7V series of ceramic and quartz crystals. The series is characterized by its small 3.2mm x 2.5mm footprint, making it suitable for space-constrained portable devices. The 7V designation typically indicates a standard commercial grade product line within the manufacturer's portfolio.

Crystals Replacement Considerations

Publicly listed parameter-equivalent substitutes include 12.60003 from Geyer Electronic America and QT325G-26.000MAHE-T from QST. These alternatives offer similar electrical characteristics and should be validated for mechanical fit and performance before adoption.
