7M-20.250MAAJ-T

Crystals Overview

The TXC Corporation 7M-20.250MAAJ-T is a surface-mount quartz crystal oscillator operating at a fundamental frequency of 20.25 MHz. It features a frequency tolerance and stability of ±30 ppm at both 25°C and across the extended temperature range of -20°C to +70°C. The component utilizes an 18 pF load capacitance and exhibits a maximum equivalent series resistance (ESR) of 60 Ohms. Designed for compact applications, it is housed in a 4-SMD, no-lead package with dimensions of 3.2 mm x 2.5 mm x 0.7 mm.

Crystals Feature Summary

• Seam seal construction utilizing ceramic materials for enhanced environmental protection
• Surface mount design compatible with standard SMD/SMT assembly processes
• Stable frequency performance maintained across specified industrial temperature ranges

Crystals Applications

• Clock signal generation for microprocessors and microcontrollers
• Timing references in communication modules

Crystals Procurement Notes

Verify that the specific ordering suffix matches the required frequency and tolerance specifications. Confirm package dimensions align with PCB footprint requirements. Ensure compliance with RoHS directives if applicable to the target market. Cross-reference datasheet parameters against circuit design constraints before finalizing procurement.

Crystals Selection Notes

Select this component when a 20.25 MHz reference is required with ±30 ppm stability. The 18 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR limit for drive level sensitivity. The 3.2x2.5 mm form factor suits space-constrained layouts requiring surface mount technology.

Crystals Part Context

This part belongs to the 7M series of seam seal crystals from TXC Corporation. These components are designed for general-purpose timing applications where moderate stability and small physical size are prioritized. The series offers various frequency options within the same mechanical footprint.

Crystals Replacement Considerations

Direct substitutes include other 20.25 MHz crystals with identical 3.2x2.5 mm packages, 18 pF load capacitance, and ±30 ppm stability. Verify ESR and drive level compatibility when replacing with parts from different manufacturers.
