XTL911100-S999-540

Crystals Overview

The Siward XTL911100-S999-540 is a surface-mount quartz crystal resonator designed for precision timing applications. It operates at a fundamental frequency of 32 MHz with a frequency tolerance of ±10 ppm. The component features a load capacitance of 8 pF and an equivalent series resistance (ESR) of 70 Ohms. It utilizes a 4-SMD, no-lead package configuration with physical dimensions of 1.2 mm in length and 1.0 mm in width. This compact form factor supports high-density PCB layouts while maintaining stable oscillation characteristics suitable for digital signal processing and communication systems.

Crystals Feature Summary

• Compact 4-SMD no-lead surface mount package design
• High frequency stability with ±10 ppm tolerance
• Optimized low ESR for efficient circuit operation

Crystals Applications

• Digital signal processing circuits
• Communication system clock sources
• Microcontroller oscillator inputs

Crystals Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and tolerance match the design requirements. Confirm the package type matches the PCB footprint exactly. Check the manufacturer datasheet for storage conditions and soldering profiles to prevent mechanical stress or frequency drift during assembly processes.

Crystals Selection Notes

Select this component when a small footprint is required alongside strict frequency accuracy. Ensure the circuit load capacitance aligns with the 8 pF specification to maintain the target frequency. Consider the 70 Ohm ESR value relative to the oscillator circuit's drive level constraints to avoid overdriving the crystal element.

Crystals Part Context

This part belongs to Siward's line of miniature surface-mount crystals. It shares the same physical envelope with other variants offering different frequencies such as 38.4 MHz or 40 MHz. The model number structure indicates specific electrical parameters, distinguishing it from larger through-hole or older SMD packages within the manufacturer's catalog.

Crystals Replacement Considerations

Direct substitutes must match the 32 MHz frequency, 8 pF load capacitance, and 4-SMD no-lead package dimensions. Verify that alternative manufacturers offer comparable ±10 ppm tolerance and similar ESR values to ensure circuit compatibility without redesign.
