S218025T-40.000-R

Oscillators Overview

The S218025T-40.000-R is a 40 MHz HCMOS crystal oscillator manufactured by Aker Technology Corp. It operates on a single 1.8V supply voltage and features an enable/disable control function for power management. The device utilizes a 4-SMD, No Lead surface mount package with dimensions of 2.00mm x 1.60mm. It provides standard frequency stability and is designed for compact electronic applications requiring precise timing signals.

Oscillators Feature Summary

• HCMOS output interface for digital logic compatibility
• Integrated enable/disable pin for active power control
• Ultra-miniature 4-pin surface mount footprint

Oscillators Applications

• Portable consumer electronics
• Communication modules
• Microprocessor clock sources

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a low-voltage, small-footprint oscillator with enable functionality is required. Consider the 40MHz frequency as the primary timing reference. Evaluate the HCMOS output swing against your downstream logic levels. Compare thermal performance and stability requirements against alternative oscillators in the same package family.

Oscillators Part Context

This part belongs to the S218025T series of ultra-miniature surface mount oscillators from Aker Technology. The series offers various frequencies including 6MHz, 20MHz, 24MHz, and 50MHz variants. These components are designed for space-constrained applications requiring reliable timing solutions with low power consumption and small physical profiles.

Oscillators Replacement Considerations

Direct replacements include other S218025T series variants such as S218025T-20.000-R or S218025T-24.000-R if different frequencies are acceptable. Cross-reference with other manufacturers offering similar 2.0x1.6mm HCMOS oscillators with enable pins. Verify electrical parameters match exactly before substitution.
