8Y-38.400MAHQ-T

Crystals Overview

The 8Y-38.400MAHQ-T is a surface-mount MHz quartz crystal resonator manufactured by TXC Corporation. It operates at a fundamental frequency of 38.4 MHz with a load capacitance of 10 pF and an equivalent series resistance (ESR) of 80 Ohms. The device features a frequency stability of ±30 ppm at 25°C and ±30 ppm across the industrial temperature range of -40°C to +85°C. Housed in a compact 4-SMD, no-lead package measuring 2.0 mm x 1.6 mm with a maximum height of 0.6 mm, it supports base harmonic operation mode.

Crystals Feature Summary

• Compact 2.0x1.6 mm surface-mount footprint for space-constrained designs
• High frequency stability of ±30 ppm across specified temperature ranges
• Seam seal ceramic construction for environmental durability
• Low ESR characteristic of 80 Ohms for efficient circuit integration

Crystals Applications

• Clock signal generation for microprocessors and microcontrollers
• Timing references for communication interfaces such as UART and SPI
• Frequency control in portable consumer electronics
• System clock sources for embedded IoT devices

Crystals Procurement Notes

Verify the specific suffix 'HQ' against official TXC documentation to confirm the exact load capacitance and tolerance specifications, as ordering suffixes define critical electrical parameters. Ensure the design accounts for the 10 pF load capacitance requirement. Confirm RoHS compliance status via the latest datasheet before finalizing procurement, as regulatory statuses may be updated by the manufacturer.

Crystals Selection Notes

Select this component when a small form factor is required alongside precise timing accuracy. The 10 pF load capacitance must match the oscillator circuit design; mismatched capacitance will cause frequency deviation. Consider the ±30 ppm stability limit for applications sensitive to long-term drift. Compare against the 7V series if a larger 3.2x2.5 mm package is acceptable for potentially different ESR characteristics.

Crystals Part Context

This part belongs to the 8Y Series of high-accuracy MHz quartz crystals from TXC Corporation. The series is characterized by seam-seal ceramic packages designed for general-purpose timing applications. It serves as a standard frequency reference component within the broader category of passive electronic components used in digital logic circuits.

Crystals Replacement Considerations

The 8Y-38.400MAHV-T is documented as a similar substitute part number from TXC Corporation. Verify that the alternative maintains the identical 10 pF load capacitance and 80 Ohm ESR values to ensure circuit compatibility without redesign.
