XTL911100-M118-190

Crystals Overview

The Siward XTL911100-M118-190 is a surface-mount quartz crystal resonator designed for precision timing applications. It operates at a fundamental frequency of 40 MHz with a frequency tolerance of ±7 ppm. The component features a load capacitance of 6 pF and an equivalent series resistance (ESR) of 50 Ohms. It is housed in a compact 4-SMD, No Lead package with dimensions of 1.2 mm by 1.0 mm. This device is suitable for integration into space-constrained electronic circuits requiring stable clock signals.

Crystals Feature Summary

• Compact 1.2 x 1.0 mm surface-mount footprint for high-density PCB layouts
• High frequency stability with ±7 ppm tolerance at 40 MHz
• Low equivalent series resistance of 50 Ohms for efficient oscillation
• RoHS compliant construction for environmental safety standards

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Consumer electronics internal clocks
• Industrial control system oscillators

Crystals Procurement Notes

Verify the specific ordering suffix M118-190 against the manufacturer's current datasheet to ensure compatibility with required soldering profiles and temperature ranges. Confirm that the 6 pF load capacitance matches the oscillator circuit design specifications. Check for RoHS compliance documentation if environmental regulations apply to the final assembly. Ensure storage conditions maintain component integrity prior to mounting.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required within a 1.2 x 1.0 mm SMD envelope. The ±7 ppm tolerance makes it suitable for general-purpose digital logic rather than high-precision RF applications. Verify that the 50 Ohm ESR aligns with the host oscillator's drive level requirements. Consider thermal performance if the operating environment exceeds standard commercial temperature limits.

Crystals Part Context

This part belongs to Siward's line of miniature quartz crystals intended for portable and embedded devices. The XTL911100 series utilizes thin-film or bulk acoustic wave technology optimized for small form factors. It complements larger through-hole crystals by providing similar electrical characteristics in a significantly reduced physical volume, facilitating modern miniaturized circuit designs.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 6 pF load capacitance, and 1.2 x 1.0 mm package dimensions. Cross-reference with other manufacturers offering 4-SMD no-lead crystals with comparable ESR and tolerance ratings. Ensure pinout compatibility and solderability meet IPC standards for the target application.
