7V-38.400MAHE-T

Crystals Overview

The 7V-38.400MAHE-T is a MHz quartz crystal manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 38.4 MHz with a frequency stability of ±30 ppm at 25°C and ±30 ppm across the -40°C to +85°C temperature range. The component utilizes a glass seal package construction within a 4-SMD, no-lead footprint measuring 3.20 mm x 2.50 mm. It features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 60 Ohms. The device supports fundamental mode operation and is compliant with RoHS3 standards.

Crystals Feature Summary

• Glass seal package construction for enhanced environmental durability
• Fundamental mode operation ensuring stable oscillation characteristics
• Surface-mount design compatible with automated assembly processes

Crystals Applications

• General-purpose clock signal generation in electronic circuits
• Timing reference sources for microcontroller systems
• Communication interface synchronization modules

Crystals Procurement Notes

Verify the specific suffix HE against official TXC documentation to confirm the 12pF load capacitance and glass seal variant, as standard MAHV variants differ. Ensure the ordering quantity aligns with manufacturer packaging standards. Cross-reference the datasheet revision date to guarantee compliance with current manufacturing specifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 38.4 MHz timing source with ±30 ppm stability is required in a compact 3.2x2.5mm package. The 12pF load capacitance specification must match the oscillator circuit design requirements. Consider the glass seal construction if superior moisture resistance or long-term reliability is prioritized over other crystal types in the 7V series.

Crystals Part Context

This part belongs to the 7V series of MHz quartz crystals from TXC Corporation. The series offers various load capacitance options and stability grades. The 7V-38.400MAHE-T specifically denotes the 12pF load capacitance variant with glass seal technology, distinguishing it from ceramic-based alternatives like the MAHV series which typically feature different load capacitances and package heights.

Crystals Replacement Considerations

Direct substitutes include the 7M-38.400MAHV-T and 7V-38.400MAHV-T, though these utilize ceramic packages and 8pF load capacitance. Verify circuit compatibility regarding load capacitance differences before substitution. Other similar parts may require adjustments to oscillator circuit components to maintain frequency accuracy.
