7V-19.200MAHE-T

Crystals Overview

The TXC CORPORATION 7V-19.200MAHE-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 19.2 MHz. It features a load capacitance of 12 pF and a frequency tolerance of ±30 ppm. The component exhibits an equivalent series resistance (ESR) of 60 ohms and is housed in a compact 4-SMD, no-lead package with dimensions of 2.50 mm x 2.00 mm. Designed for industrial applications, it supports a wide operating temperature range from -40°C to +85°C.

Crystals Feature Summary

• Provides stable clock signals via fundamental mode quartz resonance
• Supports automated assembly through surface-mount SMD packaging
• Maintains frequency stability across extended industrial temperature ranges

Crystals Applications

• Industrial control systems requiring precise timing references
• Embedded microcontroller clock sources
• Communication interface circuits

Crystals Procurement Notes

Verify the specific suffix HE against official TXC documentation to confirm the 12pF load capacitance and 60 Ohm ESR specifications. Ensure the selected variant matches the required 4-SMD footprint and -40°C to +85°C temperature rating for your design. Cross-reference the full part number with manufacturer datasheets to avoid confusion with similar models like MAHV or MAAJ which differ in load capacitance and temperature range.

Crystals Selection Notes

Select this component when a 19.2 MHz reference is needed with ±30 ppm accuracy. The 12pF load capacitance must match the oscillator circuit requirements. The 60 Ohm ESR value should be compatible with the driving circuit's power limits. Verify that the 2.50mm x 2.00mm package fits the PCB layout constraints and that the industrial temperature range meets environmental demands.

Crystals Part Context

This part belongs to the TXC 7V series of quartz crystals. It is distinct from other 19.2 MHz variants such as 7V-19.200MAHV-T, which uses an 8pF load capacitance, and 7V-19.200MAAJ-T, which has a narrower commercial temperature range. The HE suffix specifically denotes the 12pF load and 4-SMD form factor within this product line.

Crystals Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the QST QT532G-19.200MAAE-T. When replacing, verify that the substitute matches the 19.2 MHz frequency, 12pF load capacitance, and 4-SMD package dimensions.
