SX5A12.000F2010F30

Crystals Overview

The SX5A12.000F2010F30 is a surface-mount crystal resonator manufactured by Shenzhen SCTF Electronics. It operates at a fundamental frequency of 12 MHz with a frequency tolerance of ±10 ppm and a stability of ±30 ppm across the operating temperature range. The component features a load capacitance of 20 pF and an equivalent series resistance (ESR) of 60 Ohms, as indicated in distributor specifications, though other sources cite 80 Ohms. It is housed in a compact 2-SMD, No Lead package with dimensions of 5.0 x 3.2 mm, commonly referred to as SMD5032-2P. The device supports an operating temperature range from -40°C to +85°C and complies with RoHS standards.

Crystals Feature Summary

• Surface-mount design for automated assembly
• Wide operating temperature range capability
• RoHS compliant construction

Crystals Applications

• Clock signal generation in microcontroller circuits
• Timing reference for communication interfaces
• Frequency control in consumer electronics

Crystals Procurement Notes

Verify the specific Equivalent Series Resistance (ESR) value required by your circuit design, as available data sources indicate conflicting values of 60 Ohms and 80 Ohms for this part number. Confirm that the 20 pF load capacitance matches the oscillator circuit requirements. Ensure the supplier provides documentation confirming RoHS compliance and the specified ±10 ppm frequency tolerance to guarantee proper system timing accuracy.

Crystals Selection Notes

Select this component when a 12 MHz surface-mount crystal is needed for space-constrained designs. The 5.0 x 3.2 mm package offers a balance between performance and footprint. Consider the ESR discrepancy in available literature during circuit simulation to ensure stable oscillation. This part is suitable for applications requiring standard commercial temperature ranges and moderate frequency stability.

Crystals Part Context

This model belongs to the SX5A series of SMD crystals from Shenzhen SCTF Electronics. Similar parts in the lineup include the SX3B24.000F2010F30 and SX3B8.000F2010F30, which share similar packaging but differ in frequency and potentially electrical characteristics. The series generally targets general-purpose timing applications in portable and industrial electronics.

Crystals Replacement Considerations

Direct substitutes must match the 12 MHz frequency, 20 pF load capacitance, and 5.0 x 3.2 mm package. Verify ESR compatibility with the host oscillator circuit. Cross-reference with other manufacturers' 5032-2P 12MHz crystals ensuring identical tolerance and stability ratings.
