7R-31.250MAAB-T

Crystals Overview

The 7R-31.250MAAB-T is a surface-mount glass-sealed quartz crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 31.25 MHz with a load capacitance of 6 pF and an equivalent series resistance of 120 Ohms. The component features a ±30 ppm frequency tolerance and stability across the commercial temperature range of -40°C to +85°C. Housed in a compact 4-SMD, no-lead package measuring 2.0 mm x 1.6 mm with a height of 0.6 mm, it supports standard SMT assembly processes.

Crystals Feature Summary

• Glass-sealed quartz construction ensures long-term frequency stability and environmental robustness
• Compact four-terminal surface-mount footprint facilitates automated PCB assembly
• Optimized low capacitance design suitable for high-speed digital clocking circuits

Crystals Applications

• Microprocessor and microcontroller system clock generation
• Digital signal processing circuit timing references
• Communication interface synchronization modules

Crystals Procurement Notes

Verify the specific suffix MAAB against the manufacturer's current datasheet to confirm pinout and electrical parameters. Ensure the selected variant matches the required load capacitance and operating temperature range for the target application environment. Cross-reference the package dimensions with the PCB footprint library to guarantee mechanical compatibility during procurement.

Crystals Selection Notes

Select this component when a small form factor is required alongside stable quartz performance. Compare the 6 pF load capacitance against the oscillator circuit requirements to ensure proper frequency matching. Evaluate the 120 Ohm ESR against drive level constraints to prevent over-driving the crystal element during operation.

Crystals Part Context

This part belongs to the 7R series of surface-mount crystals from TXC Corporation. The series utilizes glass-sealing technology to protect the resonator element, offering superior reliability compared to standard ceramic packages. It serves as a direct replacement for legacy through-hole or larger SMD crystals where space constraints are critical.

Crystals Replacement Considerations

Direct substitutes include the 7R-31.250MAAJ-T, which shares similar packaging but may differ in load capacitance. Verify that any alternative maintains the 31.25 MHz frequency and compatible ESR values to ensure circuit functionality without redesign.
