Crystals Procurement Notes

Verify that the specific order matches the exact part number SXTF321532768A10F to ensure correct frequency and tolerance specifications. Confirm compatibility with the target PCB footprint and reflow soldering profile requirements. Request official datasheets from authorized distributors or the manufacturer to validate current production status and environmental compliance certifications before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 32.768 kHz quartz crystal is required for low-frequency timing applications. Ensure the system oscillator circuit supports a 12.5 pF load capacitance to maintain frequency accuracy. Consider the ±10 ppm stability requirement against the application's timing precision needs. Verify that the 70 kOhm ESR value aligns with the MCU or RTC controller's drive level specifications to prevent overdriving or failure to oscillate.

Crystals Part Context

This component belongs to the family of surface mount crystal resonators produced by Shenzhen SCTF Electronics. These components are designed for mass production in high-volume consumer and industrial electronics. The SXTF series typically offers standardized footprints and electrical characteristics compatible with common microcontroller architectures.
