Procurement Notes

Verify the complete part number including suffixes such as METE-T against official manufacturer documentation to ensure correct tolerance and packaging specifications. Confirm that the required frequency stability and temperature range align with the specific application requirements before finalizing procurement orders.

Selection Notes

Select this component when a 32 MHz reference signal is required in space-constrained designs. Ensure the system can accommodate a 12 pF load capacitance and that the 50 Ohm series resistance fits the oscillator circuit design constraints. Validate thermal management capabilities against the specified operating temperature limits.

Part Context

This component belongs to the QT325S series of seam-seal quartz crystals. Variants within this series differ primarily in frequency tolerance and temperature range specifications, such as the MAHE-T or MEIE-T suffixes which indicate different stability ratings. The METE-T designation specifically denotes the ±10 ppm stability configuration.

Replacement Considerations

Direct substitutes include other 32 MHz crystals with identical 3.2x2.5mm footprint and 12pF load capacitance. Verify equivalent series resistance and stability ratings. Cross-reference with TXC Corporation equivalents if supply chain diversification is required.
