25M20P2/49SMT

Crystals Overview

The YIC 25M20P2/49SMT is a surface-mount MHz crystal oscillator operating at a nominal frequency of 25 MHz. It features a load capacitance of 20 pF and a frequency tolerance of ±30 ppm. The component exhibits an equivalent series resistance (ESR) of 40 Ohms and is designed for operation within a temperature range of -20°C to +70°C. Its physical dimensions are specified as 11.40 mm in length by 4.80 mm in width, corresponding to the HC-49/US form factor adapted for surface mount technology.

Crystals Feature Summary

• Surface-mount configuration utilizing HC-49/US footprint geometry
• Stable frequency generation with ±30 ppm tolerance
• Operational reliability across industrial temperature ranges

Crystals Applications

• Microcontroller clock sources
• Communication interface timing circuits
• Digital signal processing systems

Crystals Procurement Notes

Verify that the specific order matches the SMD variant designation rather than through-hole equivalents. Confirm the load capacitance requirement aligns with the circuit design specifications. Ensure the temperature rating meets the operational environment constraints. Cross-reference the manufacturer part number with distributor catalogs to avoid confusion with similar frequency variants.

Crystals Selection Notes

Select this component when a standard 25 MHz reference is required in a compact surface-mount layout. The HC-49/US style provides mechanical robustness while allowing automated placement. Consider the ±30 ppm tolerance sufficient for general digital logic timing applications where high-precision oscillators are not mandated.

Crystals Part Context

This crystal belongs to the family of surface-mount replacements for traditional HC-49/US through-hole packages. It maintains the dimensional compatibility of the legacy style while enabling modern PCB assembly techniques. The 25 MHz frequency is a common standard for system clocks in embedded electronics.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' 25 MHz SMD crystals with identical 20 pF load capacitance and HC-49/US footprints. Verify ESR and temperature range compatibility before swapping brands.
