XTL501-M118-191

Crystals Overview

The Siward XTL501-M118-191 is a surface-mount crystal resonator designed for high-frequency applications. It operates at a nominal frequency of 80 MHz with a standard load capacitance of 8 pF. The component features a compact 2.0 x 1.6 mm package, suitable for space-constrained PCB layouts. It exhibits a frequency tolerance of ±7 ppm and an equivalent series resistance of 25 ohms. This passive frequency control element utilizes quartz piezoelectric properties to provide stable oscillation signals for digital circuits.

Crystals Feature Summary

• Compact 2.0 x 1.6 mm SMD footprint for miniaturized designs
• High-frequency operation at 80 MHz
• Precision frequency stability with ±7 ppm tolerance
• Standard 8 pF load capacitance compatibility

Crystals Applications

• Mobile communication devices requiring precise timing
• Consumer electronics with limited board space
• Digital signal processing systems
• Microcontroller clock sources

Crystals Procurement Notes

Verify the specific suffix M118-191 against the manufacturer's latest datasheet to confirm current production status and lead times. Ensure that the 8 pF load capacitance matches the oscillator circuit design requirements. Confirm package dimensions align with the intended PCB footprint. Check for any RoHS or REACH compliance documentation relevant to the manufacturing batch.

Crystals Selection Notes

Select this component when a small form factor is critical alongside high-frequency performance. The 80 MHz output suits applications needing faster clock speeds than standard 32.768 kHz crystals. Ensure the host circuit supports the 25 ohm ESR. Consider the ±7 ppm tolerance if tight frequency accuracy is required over temperature variations compared to wider tolerance alternatives.

Crystals Part Context

This part belongs to the Siward XTL501 series of surface-mount crystals. The series offers various frequencies and package sizes, including 3225 and 2520 formats. The XTL501-M118-191 specifically targets the 2016 package size, providing a balance between electrical performance and physical size for modern portable electronic devices.

Crystals Replacement Considerations

Direct substitutes include other 80 MHz crystals in a 2.0x1.6mm package with 8pF load capacitance and similar ESR. Verify pin compatibility and mounting orientation. Cross-reference with Siward models like XTL501-Q23-045 for different frequencies but identical footprints if system architecture allows frequency adjustment.
