SX2B20.000F0810F30

Crystals Overview

The SX2B20.000F0810F30 is a surface-mount AT-cut crystal manufactured by Shenzhen SCTF Electronics. It operates at a nominal frequency of 20 MHz with an initial frequency tolerance of ±10 ppm and a total frequency stability of ±30 ppm over the operating temperature range of -40°C to +85°C. The component features a load capacitance of 8 pF and an equivalent series resistance (ESR) of 60 Ω. It utilizes a miniature ceramic package with a metal lid, designed for high precision and reliability in compact electronic applications.

Crystals Feature Summary

• AT-cut crystal construction ensures high frequency stability and long-term reliability
• Ultra-miniature ceramic surface mount design with protective metal lid
• Optimized for high-temperature environments within specified industrial ranges

Crystals Applications

• Precision timing circuits requiring stable 20 MHz reference signals
• Embedded systems utilizing microcontrollers or processors
• Communication modules needing accurate clock generation

Crystals Procurement Notes

Verify that the required frequency tolerance matches the ±10 ppm specification and that the load capacitance aligns with the circuit design's 8 pF requirement. Confirm compatibility with the -40°C to +85°C operating temperature range for your specific application environment. Ensure the PCB footprint supports the 4-SMD no-lead package dimensions. Cross-reference the ESR value of 60 Ω with oscillator driver strength requirements to prevent overdriving or failure to start.

Crystals Selection Notes

Select this component when a compact, high-reliability crystal is needed for 20 MHz applications. The AT-cut construction provides superior aging characteristics compared to other cuts. Consider the metal lid feature if shielding against external interference is beneficial. Evaluate the ±30 ppm total stability against system jitter requirements. This part is suitable for designs prioritizing size reduction without sacrificing frequency accuracy in industrial conditions.

Crystals Part Context

This model belongs to the SCTF SX2B series of ultra-miniature ceramic crystals. The series is characterized by its small form factor and robust metal-lid packaging. It complements other SCTF components like the SX1B series, offering similar performance metrics in different packages. The SX2B line targets applications where space constraints are critical but high precision remains a priority.

Crystals Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 8 pF load capacitance, and 4-SMD package. Verify that alternative crystals maintain the same ±10 ppm initial tolerance and ±30 ppm stability. Check ESR compatibility to ensure oscillator circuit functionality. Ensure the replacement supports the -40°C to +85°C temperature range.
