ILCX19-HH5F10-25.000MHZ

Crystals Overview

ILCX19-HH5F10-25.000MHZ is a parallel fundamental quartz crystal operating at a nominal frequency of 25.000 MHz. It features a 4-pad surface mount ceramic package with dimensions of 2.0mm x 1.6mm x 0.55mm. The component specifies a load capacitance of 10pF and a maximum equivalent series resistance of 80 Ohms. Frequency tolerance is ±20ppm at 25°C, with stability defined by the ILCX19 series parameters.

Crystals Feature Summary

• Ultra miniature 4-pad SMD ceramic package design
• Compatible with lead-free processing standards
• Low cost surface mount configuration

Crystals Applications

• Sonet / SDH systems
• 802.11 / WiFi networks
• T1/E1 and T3/E3 interfaces

Crystals Procurement Notes

Verify that the ordering suffix matches the required frequency tolerance and load capacitance specifications for the target circuit. Confirm the package type corresponds to the PCB footprint requirements. Ensure compliance with RoHS directives if environmental regulations apply to the assembly process.

Crystals Selection Notes

Select this component when a 25 MHz reference is required in a compact form factor. The 80 Ohm ESR limit must align with the oscillator circuit drive conditions. Verify that the ±20ppm tolerance meets the system timing accuracy requirements compared to tighter or looser available options.

Crystals Part Context

This part belongs to the ILCX19 series of ultra-miniature quartz crystals manufactured by ILSI America. The series utilizes AT-cut resonators packaged in small surface-mount footprints designed for high-density board layouts. These components are engineered for general-purpose clocking applications requiring stable frequency generation.

Crystals Replacement Considerations

Direct substitutes include other ILCX19 variants with matching 25 MHz frequency, 10pF load capacitance, and 80 Ohm ESR limits. Cross-referencing requires verifying identical package dimensions and pinout configurations to ensure mechanical compatibility.
