S118025T-40.000-R

Oscillators Overview

The S118025T-40.000-R is a standard crystal oscillator (XO) manufactured by Aker Technology Corp, designed for surface-mount applications. It operates at a nominal frequency of 40 MHz and utilizes HCMOS output logic levels. The device supports a supply voltage range that includes 1.8V operation with dedicated enable/disable functionality. It is housed in a compact 4-SMD, no-lead package, suitable for automated assembly processes. The component is RoHS compliant and lead-free, ensuring adherence to environmental standards for electronic components used in modern consumer and industrial electronics.

Oscillators Feature Summary

• HCMOS output signal compatibility
• Integrated enable and disable control pin
• Ultra-miniature surface-mount form factor

Oscillators Applications

• General-purpose digital timing references
• Microprocessor clock sources
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V enable/disable feature aligns with your system's power management strategy. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any recent revisions to the datasheet regarding electrical characteristics or mechanical dimensions.

Oscillators Selection Notes

Select this component when a low-profile, standard-frequency oscillator with CMOS output is required. Consider the 1.8V enable feature if power conservation during idle states is critical. Evaluate the package size against available board space. Compare phase noise specifications with other models in the series if jitter sensitivity is high in the application.

Oscillators Part Context

This part belongs to Aker Technology's S118025T series of ultra-miniature oscillators. The series offers various frequencies and voltage options within a consistent 4-pin SMD package. It is distinct from TCXO or VCXO variants which offer tighter stability or tuning capabilities. The 'R' suffix typically indicates tape-and-reel packaging for high-volume manufacturing.

Oscillators Replacement Considerations

Direct replacements must match the 40 MHz frequency, HCMOS output, and 4-SMD package. Verify voltage compatibility, particularly the 1.8V enable threshold. Cross-reference with other Aker models like S118025T-40.000-X-R only if package or tolerance differences are acceptable.
