7M-19.200MAHV-T

Crystals Overview

The 7M-19.200MAHV-T is a quartz crystal resonator manufactured by TXC Corporation, operating at a fundamental frequency of 19.2 MHz. It features a frequency tolerance and stability of ±30 ppm across an extended industrial temperature range of -40°C to +85°C. The component utilizes a load capacitance of 8 pF and exhibits an equivalent series resistance (ESR) of 80 ohms with a drive level of 10 µW. Housed in a compact 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm, it supports surface-mount assembly for high-density circuit designs.

Crystals Procurement Notes

Verify the specific suffix HV against the official TXC datasheet to confirm package dimensions and soldering profile requirements. Ensure the design accounts for the 8 pF load capacitance to maintain frequency accuracy. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement specifications.

Crystals Selection Notes

Select this component when a 19.2 MHz reference is required within a 3.2x2.5 mm SMD footprint. The ±30 ppm stability suits general-purpose digital logic applications. Consider the 80 ohm ESR value for oscillator circuit loading calculations. Compare against the 7V series if different load capacitance or packaging options are needed for the target application.

Crystals Part Context

This part belongs to the TXC 7M series of quartz crystals, designed for surface-mount technology. The series provides reliable frequency generation for embedded systems. The 7M designation indicates specific manufacturing processes and material compositions optimized for modern reflow soldering techniques and automated placement equipment.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers include 7V-19.200MAHV-T and 7B-19.200MAAJ-T from TXC Corporation. Verify that alternative parts match the 19.2 MHz frequency, 8 pF load capacitance, and 4-SMD package dimensions to ensure mechanical and electrical compatibility.
