7B-20.000MAAJ-T

Crystals Overview

The 7B-20.000MAAJ-T is a quartz crystal resonator manufactured by TXC Corporation, operating at a fundamental frequency of 20 MHz. It features a frequency tolerance and stability of ±30 ppm. The component utilizes an 18 pF load capacitance and has a maximum equivalent series resistance (ESR) of 40 Ohms. Designed for surface-mount applications, it is housed in a 4-SMD, No Lead package with dimensions of 5.00 mm x 3.20 mm x 1.05 mm. The device supports a base harmonic mode and operates within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Utilizes a 4-SMD, No Lead surface-mount package for compact circuit integration.
• Provides stable oscillation at 20 MHz with ±30 ppm frequency tolerance.
• Operates on the fundamental harmonic mode for precise timing control.

Crystals Applications

• General-purpose digital clock signal generation
• Microcontroller system timing references
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific suffix 'T' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 18 pF load capacitance matches the oscillator circuit design specifications to ensure accurate frequency performance. Check the RoHS3 compliance status if environmental regulations apply to the final product assembly.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with ±30 ppm stability is required for space-constrained designs. Ensure the operating environment remains within the -20°C to +70°C range. Compare against alternative packages if higher thermal ranges or different mounting styles are necessary for the application.

Crystals Part Context

This part belongs to the 7B series of quartz crystals from TXC Corporation. The series is characterized by standard SMD footprints suitable for general electronics. The 7B designation indicates a specific physical dimension and electrical profile distinct from other series like 7A or AA.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 7B-20.000MAAE-T and 7V-20.000MAAE-T from TXC Corporation. Cross-manufacturer replacements such as ABM8G-20.000MHZ-B4Y-T from Abracon LLC are also documented as similar alternatives.
