XTL901150-M118-185

Crystals Overview

The Siward XTL901150-M118-185 is a 52 MHz fundamental mode quartz crystal resonator designed for surface-mount applications. It features an 8 pF load capacitance and offers a frequency tolerance of ±7 ppm at room temperature, with a total stability of ±15 ppm across the operating range. The component operates within a temperature range of -40°C to +100°C. It utilizes a 4-SMD, no-lead package with dimensions of 1.6 mm x 1.2 mm and a maximum seated height of 0.35 mm. This device complies with ROHS3 standards.

Crystals Feature Summary

• Compact 1.6mm x 1.2mm surface-mount footprint suitable for space-constrained designs
• High frequency stability with ±15ppm total stability over extended temperature ranges
• Lead-free construction compliant with ROHS3 environmental standards

Crystals Applications

• Microcontroller clock sources in embedded systems
• Communication module timing references
• Portable electronic device oscillators

Crystals Procurement Notes

Verify the specific suffix codes against official Siward documentation to ensure exact electrical parameters match design requirements. Confirm that the 4-SMD no-lead package aligns with PCB land pattern specifications. Check for updated compliance certifications such as ROHS3 status directly from manufacturer datasheets prior to final procurement decisions.

Crystals Selection Notes

Select this component when a small form factor is required alongside precise frequency control. Ensure the circuit design supports an 8pF load capacitance to maintain accuracy. Consider the -40°C to +100°C operating range for industrial or automotive environments where standard commercial grade crystals may fail.

Crystals Part Context

This part belongs to the Siward XTL90 series of miniature crystals. It is distinct from larger packages like the 3.2x2.5mm variants found in other series. The model number encodes specific frequency and package details, differentiating it from similar 52MHz parts with different tolerances or load capacitances.

Crystals Replacement Considerations

Direct substitutes must match the 52MHz frequency, 8pF load capacitance, and 1.6x1.2mm SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering equivalent 4-SMD no-lead crystals with comparable stability ratings.
