Crystals Procurement Notes

Verify the complete part number including suffixes such as K3 or K0, as these indicate specific packaging or tape-and-reel configurations that may affect handling. Confirm the load capacitance requirement matches the target circuit design to ensure accurate oscillation. Check the datasheet for the latest mechanical drawings and soldering profile recommendations to prevent thermal damage during assembly.

Crystals Selection Notes

Select this component when a precise 25 MHz reference is required for space-constrained designs. Ensure the application circuit provides the specified 10 pF load capacitance to maintain the stated ±10 ppm accuracy. Consider the ESR value of 80 Ohms when evaluating oscillator circuit stability and startup time requirements for the specific microcontroller or logic family being used.

Crystals Part Context

This part belongs to the FA-20H series of ultra-small crystals from EPSON Timing. The series is characterized by its compact 2.0mm x 2.5mm footprint, which allows for high-density PCB layouts. The FA-20H line is engineered for low power consumption and robust performance across varying environmental conditions, making it suitable for portable and industrial electronics.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 10 pF load capacitance, and 2.0x2.5mm package dimensions. Verify that alternative components offer comparable ESR values and frequency stability to ensure circuit compatibility. Cross-reference manufacturer datasheets for pinout and electrical parameter alignment before integration.
