Crystals Overview

The YIC 10M20P2/49SMT is a passive quartz crystal resonator designed for surface-mount technology applications. It operates at a fundamental frequency of 10 MHz with a tolerance of ±30 ppm. The component features a load capacitance of 20 pF and an equivalent series resistance (ESR) of 50 Ohms. It utilizes the HC-49/US package style, providing a compact form factor suitable for automated assembly processes while maintaining standard electrical characteristics for clock generation circuits.

Crystals Feature Summary

• Surface-mount construction compatible with automated pick-and-place manufacturing
• Fundamental mode operation ensuring stable frequency generation
• Standardized HC-49/US mechanical footprint for board layout consistency

Crystals Applications

• Microcontroller clock source generation
• Digital logic circuit timing references
• Communication interface synchronization

Crystals Procurement Notes

Verify that the specific order matches the HC-49/US surface-mount variant rather than through-hole equivalents. Confirm the load capacitance requirement aligns with the target oscillator circuit design to ensure frequency accuracy. Check packaging specifications for tape and reel requirements if using automated placement equipment. Ensure environmental ratings meet the operational temperature range of the final application.

Crystals Selection Notes

Select this component when a 10 MHz reference signal is required in a space-constrained surface-mount design. Evaluate the ±30 ppm tolerance against the system's frequency stability needs. Consider the 20 pF load capacitance compatibility with the host oscillator's internal capacitors. Assess the 50 Ohm ESR to ensure it falls within the driving strength limits of the connected integrated circuit.

Crystals Part Context

This part belongs to the YIC family of MHz-range surface-mount crystals. It complements through-hole variants like the 49US and 49SL by offering a similar electrical profile in a modern SMD format. The product line focuses on providing reliable frequency control solutions for general-purpose electronic devices requiring precise timing signals.

Crystals Replacement Considerations

Cross-reference with other manufacturers offering HC-49/US SMD packages at 10 MHz. Verify pin compatibility and mechanical dimensions before substitution. Ensure equivalent electrical parameters including load capacitance and ESR are matched to maintain circuit performance.
