SX3B25.000F1210F30

Crystals Overview

The SX3B25.000F1210F30 is a surface-mount quartz crystal resonator manufactured by Shenzhen SCTF Electronics. It operates at a fundamental frequency of 25 MHz with a load capacitance of 12 pF and an equivalent series resistance (ESR) of 30 Ohms. The component features a ±10 ppm frequency tolerance at room temperature and utilizes AT-cut technology for stability. It is housed in a compact SMD3225-4P package, designed for reliable performance in consumer and industrial temperature ranges.

Crystals Feature Summary

• AT-cut quartz structure for high precision
• Ultra-small ceramic surface mount design
• Metal cover construction for protection

Crystals Applications

• Consumer electronics timing circuits
• Industrial control system oscillators
• Microprocessor clock generation

Crystals Procurement Notes

Verify the manufacturer designation as Shenzhen SCTF Electronics against official component documentation. Confirm that the SMD3225-4P package dimensions align with specific board layout requirements. Ensure the 12 pF load capacitance matches the target circuit design to maintain the specified ±10 ppm accuracy. Cross-reference the ESR value of 30 Ohms with oscillator driver strength specifications.

Crystals Selection Notes

Select this component when a 25 MHz reference signal is required in a space-constrained application. The 12 pF load capacitance dictates compatibility with specific microcontroller or oscillator IC inputs. The 30 Ohm ESR influences drive level sensitivity; ensure the host circuit does not exceed the maximum drive power rating. The SMD3225-4P form factor offers a balance between thermal mass and footprint efficiency.

Crystals Part Context

This part belongs to the family of surface-mount quartz crystal resonators. It serves as a passive frequency-determining element in electronic circuits. Unlike active oscillators, it requires an external oscillator circuit to generate a square wave output. The SMD3225-4P package is standard for general-purpose timing applications where moderate stability is sufficient.

Crystals Replacement Considerations

Substitute parts must match the 25 MHz frequency, 12 pF load capacitance, and SMD3225-4P package. Verify that alternative manufacturers specify compatible ESR values near 30 Ohms to prevent overdriving the crystal. Check that the replacement part supports the required operating temperature range.
