SXTF321532768G10F

Crystals Overview

The SXTF321532768G10F is a passive surface-mount crystal resonator manufactured by Shenzhen SCTF Electronics. It operates at a fundamental frequency of 32.768 kHz, a standard rate for real-time clock applications. The component exhibits a nominal load capacitance of 9pF and maintains a temperature stability of ±30ppm across its operating range. Its equivalent series resistance (ESR) is specified at 70kΩ, while the initial frequency tolerance at room temperature is ±10ppm. This device utilizes a two-terminal no-lead surface mount package, designed for integration into compact electronic circuits requiring precise low-frequency timing references.

Crystals Feature Summary

• Provides stable 32.768 kHz timing reference for real-time clock synchronization
• Utilizes surface-mount technology for automated PCB assembly compatibility
• Maintains strict frequency tolerance within defined thermal operating limits

Crystals Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system timing references
• Low-power embedded devices requiring precise timekeeping

Crystals Procurement Notes

Verify the specific suffix G10F against the manufacturer's latest specification sheet to ensure compliance with current RoHS and REACH directives. Confirm that the 9pF load capacitance matches the oscillator circuit design requirements on the target PCB. Validate the ESR value of 70kΩ against the host controller's drive level specifications to prevent overdriving or failure to oscillate. Ensure the surface mount footprint aligns with the board layout guidelines provided in the official datasheet.

Crystals Selection Notes

Select this component when a 32.768 kHz frequency is required for timekeeping functions. The 9pF load capacitance dictates the external capacitor values needed for circuit tuning. The ±10ppm initial accuracy suits applications where moderate precision is acceptable. Consider the 70kΩ ESR when designing the oscillator feedback network. This part is suitable for general-purpose timing rather than high-stability navigation or telecommunications infrastructure.

Crystals Part Context

This model belongs to the SXTF series of quartz crystal resonators from Shenzhen SCTF Electronics. The series focuses on providing reliable frequency control solutions for mass-market electronics. As a passive component, it requires an external oscillator circuit to function. The company emphasizes ISO9001 certification and global supply capabilities for these standard frequency components.

Crystals Replacement Considerations

The SXTF321532768A10F is a documented alternative variant within the same product family, featuring a 12.5pF load capacitance instead of 9pF. Verify circuit compatibility before substitution due to the difference in load capacitance requirements.
