7V-28.63636MAAJ-T

Crystals Overview

The 7V-28.63636MAAJ-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation. It operates at a nominal frequency of 28.63636 MHz with a frequency tolerance and stability of ±30 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 60 Ohms. It utilizes fundamental oscillation mode and is housed in a compact 4-SMD, no-lead package measuring 3.2 mm x 2.5 mm with a maximum height of 0.8 mm. The device supports operation within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Provides precise timing signals at 28.63636 MHz with stable frequency performance
• Designed for surface-mount assembly using a compact 3.2mm x 2.5mm footprint
• Operates reliably across specified industrial temperature ranges

Crystals Applications

• Digital signal processing circuits requiring precise clock references
• Communication systems utilizing standard baud rates derived from 28.63636 MHz
• Microcontroller-based embedded systems needing stable oscillator sources

Crystals Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm that the operating temperature range of -20°C to +70°C meets application requirements, as this differs from wider automotive grades. Ensure the 18pF load capacitance matches the host circuit design specifications before integration.

Crystals Selection Notes

Select this component when a 28.63636 MHz frequency is required for data communication standards. Consider the 60 Ohm ESR value for oscillator circuit compatibility. The 3.2x2.5mm SMD package offers space efficiency compared to larger through-hole alternatives while maintaining necessary electrical characteristics for digital logic interfaces.

Crystals Part Context

This part belongs to the 7V series of quartz crystals from TXC Corporation. The series focuses on general-purpose surface-mount resonators suitable for consumer electronics and industrial applications. The 7V designation distinguishes it from other TXC families like the 7A or AV series, which may offer different temperature ranges or certifications.

Crystals Replacement Considerations

Direct substitutes include the 7M-28.63636MAHE-T, though it specifies a 12pF load capacitance instead of 18pF. The AU-28.63636MBE-T is an active oscillator, not a passive crystal, requiring different circuit topology. Verify parameter alignment before substitution.
