QT325G-30.000MAAV-T

Overview

The QT325G-30.000MAAV-T is a surface-mount quartz crystal oscillator manufactured by TXC Corporation under the QST brand. It operates at a fundamental frequency of 30 MHz with a load capacitance of 8 pF. The component features a glass seal package with dimensions of 3.2 mm x 2.5 mm and a height of 0.8 mm. Frequency stability is specified at ±30 ppm over the temperature range of -20°C to +70°C, and ±30 ppm at 25°C. The equivalent series resistance (ESR) is typically 100 ohms. This device utilizes a four-terminal SMD no-lead configuration for reliable circuit integration.

Feature Summary

Procurement Notes

Verify the manufacturer part number QT325G-30.000MAAV-T against official TXC Corporation documentation to confirm authenticity. Ensure the received components match the specified 3.2x2.5mm package dimensions and 8pF load capacitance. Check for physical damage to the glass seal or solder pads prior to assembly. Confirm that the supplier provides valid traceability data consistent with factory-sealed packaging standards.

Selection Notes

Select this component when a 30 MHz fundamental frequency crystal is required for space-constrained designs. The 8pF load capacitance must align with the host oscillator circuit's requirements. Consider the ±30ppm stability specification relative to environmental temperature variations. The 100 ohm ESR value impacts startup margin and should be evaluated against power consumption constraints in the target application design.

Part Context

This component belongs to the QT325G series of surface-mount quartz crystals. The series offers various frequency options within a standardized 3.2x2.5mm footprint. The specific model denotes a 30 MHz variant with 8pF load capacitance. The series is designed for applications demanding reliable timing solutions in compact electronic assemblies.

Replacement Considerations

Compatible substitutes include other 30 MHz crystals with identical 3.2x2.5mm dimensions and 8pF load capacitance. Verify that alternative parts maintain similar ±30ppm stability and ESR specifications. Ensure the replacement component supports the same operating temperature range and mounting requirements.
