IXA16-HF5F12-25.000MHZ

Crystals Overview

The IXA16-HF5F12-25.000MHZ is a parallel fundamental quartz crystal manufactured by ILSI, designed for surface-mount applications. It operates at a nominal frequency of 25.000 MHz with a load capacitance of 12 pF and an equivalent series resistance (ESR) of 60 Ohms maximum. The component features a frequency tolerance of ±20 ppm at 25°C and stability of ±30 ppm over the operating temperature range. It supports a drive level of 100 µW and exhibits aging of 5 ppm per year maximum. The device is housed in a 4-pin SMD package with dimensions of 3.2 mm x 2.5 mm x 1.1 mm, suitable for lead-free processing.

• General-purpose microcontroller clock sources

Crystals Procurement Notes

Verify the specific ordering suffix against the official ILSI datasheet to confirm exact frequency tolerance, stability, and aging specifications. Ensure the selected variant matches the required load capacitance and ESR for the target oscillator circuit. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the package dimensions with PCB footprint libraries to ensure mechanical compatibility during layout.

Crystals Selection Notes

Select this component when a 25 MHz reference is required in a compact surface-mount form factor. The 12 pF load capacitance must match the oscillator circuit design to achieve the specified ±20 ppm tolerance. Consider the 60 Ohm ESR limit to ensure sufficient loop gain in the driving circuitry. This part is suitable for commercial temperature ranges; verify if extended temperature ratings are necessary for the specific application environment.

Crystals Part Context

This crystal belongs to the IXA16 series from ILSI, which focuses on small-footprint timing solutions. The series utilizes AT-cut quartz resonators encapsulated in ceramic packages to provide reliable performance in high-volume consumer and industrial electronics. The 3225 package size balances miniaturization with thermal and mechanical robustness for standard reflow soldering profiles.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz crystals with identical 3225 SMD footprints, 12 pF load capacitance, and ≤60 Ohm ESR. Verify that alternative manufacturers offer matching ±20 ppm tolerance and similar aging rates to maintain system timing integrity without circuit redesign.
