7A-24.000MAHE-T

Crystals Overview

The 7A-24.000MAHE-T is a surface-mount quartz crystal manufactured by TXC Corporation, operating at a fundamental frequency of 24 MHz. It features a frequency tolerance and stability of ±30 ppm across the industrial temperature range of -40°C to +85°C. The component utilizes a 12 pF load capacitance and exhibits an equivalent series resistance (ESR) of 50 Ohms. Designed for compact electronics, it is housed in a 2-SMD, no-lead package with dimensions of 5.0 mm in length, 3.2 mm in width, and 1.6 mm in height.

Crystals Feature Summary

• Glass-sealed construction provides enhanced environmental reliability and moisture resistance compared to standard ceramic packages.
• Optimized for SMT assembly processes, ensuring compatibility with standard reflow soldering profiles.
• Low drive level operation minimizes power consumption, making it suitable for battery-powered portable devices.

Crystals Applications

• Portable USB data acquisition cards
• Personal Digital Assistants (PDAs)
• Digital cameras
• USB interface cards

Crystals Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notifications prior to procurement. Ensure supply chain documentation matches the specific manufacturing lot requirements for quality assurance.

Crystals Selection Notes

Select this component when a 24 MHz clock source is required within a 5.0 x 3.2 mm footprint. It is appropriate for designs needing ±30 ppm stability over a wide industrial temperature range. Consider glass-seal benefits for harsh environments where ceramic packages may fail due to thermal stress or humidity.

Crystals Part Context

This part belongs to the TXC 7A series, which specializes in 3225-sized glass-sealed crystals. The series targets high-reliability applications requiring robust performance against environmental factors. It serves as a specialized alternative to standard ceramic crystals in space-constrained consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes include other 24 MHz crystals with identical 3225 footprints and ±30 ppm stability. Verify that replacement parts maintain the same 12 pF load capacitance and ESR specifications to ensure circuit compatibility without redesign.
