7M-38.400MAHV-T

Crystals Overview

The TXC Corporation 7M-38.400MAHV-T is a fundamental mode quartz crystal resonator designed for surface mount applications. It operates at a nominal frequency of 38.4 MHz with a frequency stability and tolerance of ±30 ppm. The component features an equivalent series resistance (ESR) of 60 Ohms and requires a load capacitance of 8 pF. It is housed in a compact 4-SMD, no-lead package measuring 3.20 mm in length, 2.50 mm in width, and 0.80 mm in maximum height. The device supports a standard operating temperature range from -40°C to +85°C and utilizes SMD/SMT termination types for automated assembly processes.

Crystals Feature Summary

• Fundamental oscillation mode ensures stable frequency generation within the specified tolerance.
• Compact 4-SMD no-lead footprint facilitates efficient surface mount placement on PCBs.
• Wide industrial temperature rating allows reliable operation across extreme environmental conditions.

Crystals Applications

• Clock signal generation for microcontrollers and digital logic circuits
• Timing references in communication modules and data transmission systems
• Frequency control in consumer electronics and embedded devices

Crystals Procurement Notes

Verify that the replacement circuit design accounts for the specific 8 pF load capacitance requirement to ensure accurate frequency performance. Confirm that the target application environment remains within the specified -40°C to +85°C operational range. Ensure that the PCB layout adheres to the recommended footprints for the 4-SMD no-lead package to maintain mechanical integrity and electrical reliability during soldering.

Crystals Selection Notes

Select this component when a fundamental mode crystal with ±30 ppm stability is required for 38.4 MHz applications. Consider the 60 Ohm ESR value when designing oscillator circuits to guarantee startup reliability. The choice is appropriate for space-constrained designs due to the small 3.2x2.5 mm package dimensions. Verify compatibility with the system's load capacitance requirements before finalizing the bill of materials.
