QT252S-48.000MAAE-T

Overview

The QT252S-48.000MAAE-T is a quartz crystal resonator manufactured by TXC Corporation under the QST brand. It operates at a fundamental frequency of 48 MHz with a load capacitance of 12 pF. The component features a 4-SMD, No Lead package with dimensions of 2.5 mm x 2.0 mm. Frequency stability is rated at ±30 ppm at 25°C and ±30 ppm over the temperature range of -20°C to +70°C.

Feature Summary

• Seam seal construction for environmental protection
• Surface mount design compatible with automated assembly
• High frequency stability within specified industrial temperature ranges

Applications

• Precision timing circuits in communication equipment
• Clock generation for microprocessors and digital logic
• Frequency reference sources in consumer electronics

Procurement Notes

Verify manufacturer part number alignment between TXC Corporation specifications and QST branding. Confirm package type matches 4-SMD No Lead requirements. Ensure load capacitance parameters match circuit design needs before procurement.

Selection Notes

Select this component when a 48 MHz reference with ±30 ppm stability is required in a compact surface mount form factor. Consider thermal performance limits between -20°C and +70°C. Verify compatibility with 12 pF load capacitance in target oscillator circuits.

Part Context

Part of the QT252S series of seam seal crystals. Shares common package dimensions and mounting characteristics with other variants in the family while differing in frequency and stability specifications.

Replacement Considerations

QT252S-48.000MAHE-T offers similar frequency but different temperature range (-40 to 85°C). QT252S-48.000MEEV-T provides higher stability (±10ppm) with 8pF load capacitance.
