XTL581120-M118-172

Crystals Overview

The Siward XTL581120-M118-172 is a surface-mount quartz crystal resonator designed for precision timing applications. It operates at a fundamental frequency of 26 MHz with a frequency tolerance of ±7 ppm. The component features an 8 pF load capacitance and a maximum equivalent series resistance (ESR) of 30 Ohms. It utilizes a 4-SMD, no-lead package configuration with physical dimensions of 2.5 mm by 2.0 mm. This unit is engineered to provide stable oscillation in compact electronic designs requiring accurate clock signals.

• Provides precise 26 MHz oscillation with tight ±7 ppm frequency stability
• Compact 2.5 x 2.0 mm surface-mount footprint suitable for space-constrained layouts
• Low equivalent series resistance of 30 Ohms for efficient circuit integration

Crystals Applications

• Mobile phone baseband processing units
• Wireless communication module clock generation
• Portable consumer electronics timing references

Crystals Procurement Notes

Verify the specific ordering suffix M118-172 against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the 4-SMD no-lead package matches your PCB land pattern design. Check for any recent updates to the RoHS compliance status or material declarations prior to finalizing procurement orders to meet regulatory requirements.

Crystals Selection Notes

Select this component when a 26 MHz reference with ±7 ppm accuracy is required in a 2520 package. Ensure the circuit design supports an 8 pF load capacitance to maintain frequency accuracy. Compare ESR limits against oscillator driver strength to prevent startup failures. Validate that the operating temperature range aligns with the intended application environment before implementation.

Crystals Part Context

This part belongs to the Siward XTL58 series of ultra-miniature crystals. The series focuses on providing high-frequency stability in small form factors for portable devices. Siward manufactures these components using synthetic quartz technology to ensure consistent performance across production batches. The XTL58 line is widely used in mobile and wireless industries where size and precision are critical constraints.

Crystals Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 8 pF load capacitance, and 2520 package dimensions. Verify that alternative parts offer equal or better frequency tolerance and ESR specifications. Cross-reference pinout configurations if available, though SMD crystals typically lack polarity. Consult manufacturer cross-reference guides for verified equivalents.
