7V-30.000MAAQ-T

Crystals Overview

The 7V-30.000MAAQ-T is a fundamental mode quartz crystal resonator manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 30 MHz with a load capacitance of 10 pF and an equivalent series resistance (ESR) of 60 Ohms. The component exhibits a frequency tolerance and stability of ±30 ppm. It features a compact 4-SMD, no-lead package measuring 3.2 mm in length, 2.5 mm in width, and 0.90 mm in maximum height. This device is suitable for integration into electronic circuits requiring precise timing signals.

Crystals Feature Summary

• Fundamental oscillation mode operation for stable signal generation
• Compact surface-mount footprint facilitating automated assembly
• Defined load capacitance and ESR specifications for circuit compatibility

Crystals Applications

• General-purpose timing circuits
• Microcontroller clock sources
• Communication interface modules

Crystals Procurement Notes

Verify the specific operating temperature range and any automotive qualification status directly against the official manufacturer datasheet, as distributor summaries may omit critical environmental constraints. Confirm that the 10 pF load capacitance aligns with the target oscillator circuit design to ensure frequency accuracy. Ensure the 60 Ohm ESR value is within the acceptable limits of the host system's driving capability to prevent overdriving or startup failures.

Crystals Selection Notes

Select this component when a 30 MHz fundamental frequency with ±30 ppm stability is required in a small SMD form factor. The 10 pF load capacitance dictates the external capacitor values needed for the oscillator circuit. Consider the 60 Ohm ESR when designing for low-power consumption or specific drive level requirements. Verify package dimensions against PCB silkscreen and footprint guidelines to ensure mechanical fit during layout.

Crystals Part Context

This part belongs to the 7V series of crystals from TXC Corporation, characterized by standard surface-mount packaging. It serves as a passive timing element distinct from active oscillators, relying on external amplifier circuits to sustain oscillation. The 4-SMD no-lead configuration distinguishes it from through-hole alternatives, offering improved thermal performance and space efficiency for modern consumer electronics.

Crystals Replacement Considerations

Direct substitutes include other 30 MHz crystals with identical 10 pF load capacitance, ±30 ppm tolerance, and compatible ESR values. Cross-reference package dimensions (3.2 x 2.5 x 0.90 mm) to ensure mechanical interchangeability. Verify that alternative manufacturers specify the same fundamental mode operation and drive level sensitivity to maintain circuit performance without redesign.
