XTL581150-S315-028

Crystals Overview

The Siward XTL581150-S315-028 is a surface-mount quartz crystal resonator designed for precision frequency control applications. It operates at a fundamental frequency of 26 MHz with a load capacitance of 9 pF and an equivalent series resistance (ESR) of 60 Ohms. The component features a ±5 ppm frequency tolerance at room temperature, ensuring high stability in timing circuits. Housed in a compact 4-SMD, no-lead package measuring 2.5 x 2.0 mm, it offers reliable performance for space-constrained designs requiring accurate clock signals.

Crystals Feature Summary

• High frequency stability with ±5 ppm tolerance
• Compact surface-mount footprint for automated assembly
• Low equivalent series resistance for efficient oscillation

Crystals Applications

• Microcontroller clock sources
• Communication module timing
• Consumer electronics oscillators

Crystals Procurement Notes

Verify the specific suffix S315-028 against the manufacturer's latest datasheet to confirm load capacitance and ESR values. Ensure compatibility with reflow soldering profiles specified for 4-SMD packages. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Crystals Selection Notes

Select this component when a 26 MHz reference with tight tolerance is required. Consider the 9 pF load capacitance requirement for oscillator circuit design. Evaluate the 60 Ohm ESR against the host oscillator's drive level specifications to prevent overdriving the crystal.

Crystals Part Context

This part belongs to Siward's XTL581150 series of surface-mount crystals. The series provides various frequency options and package sizes for general-purpose timing applications. Siward manufactures these components using high-purity quartz materials to ensure long-term reliability and consistent electrical characteristics across production batches.

Crystals Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 9 pF load capacitance, and 4-SMD 2.5x2.0mm package dimensions. Verify that alternative manufacturers offer comparable ±5 ppm tolerance and similar ESR values to maintain circuit performance.
