QT252S-26.000MAHQ-T

Overview

The QT252S-26.000MAHQ-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 26 MHz with a load capacitance of 10 pF and an equivalent series resistance (ESR) of 100 Ohms. The component features a 4-SMD, no-lead package with dimensions of 2.5 x 2.0 x 0.55 mm. Frequency stability is rated at ±30 ppm across the operating temperature range.

Feature Summary

• Utilizes a 2.5x2.0 mm seam seal SMD package for compact circuit integration
• Provides stable oscillation at 26 MHz with 10 pF load capacitance
• Ensures frequency accuracy within ±30 ppm tolerance

Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuits

Procurement Notes

Verify the manufacturer designation, as some listings associate this part number with QST while others reference TXC Corporation. Confirm the specific package dimensions and electrical parameters against the official datasheet to ensure compatibility with the target design requirements before procurement.

Selection Notes

Select this component when a 26 MHz reference is required in a small form factor. Ensure the application circuit supports a 10 pF load capacitance and can accommodate an ESR of 100 Ohms. Verify that the ±30 ppm stability meets the system's timing precision needs.

Part Context

This part belongs to the QT252S series of surface-mount quartz crystals. The series offers various frequencies and stability options in a standardized 2.5x2.0 mm footprint, suitable for space-constrained electronic designs requiring reliable frequency generation.

Replacement Considerations

Direct substitutes include other 26 MHz crystals with identical 2.5x2.0 mm SMD packages, 10 pF load capacitance, and similar ESR values. Cross-reference with QT252S-26.000MDDQ-T or similar variants from compatible manufacturers if pinout and electrical specs match.
