The component features a frequency tolerance of ±20 ppm and stability of ±50 ppm. It utilizes a 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm. Key electrical parameters include an equivalent series resistance (ESR) of 50 Ohms and a drive level of 1 mW.

Feature Summary

• Utilizes a compact surface-mount SMD package for automated assembly
• Provides stable frequency generation at 25 MHz
• Designed for general clocking applications in electronic circuits

Applications

• Microcontroller clock sources
• Communication interface timing
• General purpose digital circuit oscillation

Procurement Notes

Verify the specific ordering suffix and package variant against the official IQD datasheet to ensure compatibility with your PCB footprint. Confirm that the 18 pF load capacitance matches your oscillator circuit design requirements. Check current availability status as supply chain conditions may vary. Ensure compliance with RoHS directives if required for your manufacturing process.

Selection Notes

Select this component when a 25 MHz fundamental frequency is required in a small form factor. The 18 pF load capacitance must align with the host oscillator's specified load. Consider the ±20 ppm tolerance for precision timing needs. The 4-SMD package facilitates reflow soldering processes. Evaluate the ESR value against the oscillator driver strength capabilities.
