405I35D25M00000

Crystals Overview

The CTS-Frequency Controls 405I35D25M00000 is a fundamental mode quartz crystal resonator designed for surface mount applications. It operates at a nominal frequency of 25 MHz with a load capacitance of 18 pF and a frequency tolerance of ±30 ppm. The device features an equivalent series resistance (ESR) of 50 Ohms and maintains a frequency stability of ±50 ppm across the industrial temperature range of -40°C to +85°C. Housed in a compact 4-SMD, no-lead package measuring 5.00mm x 3.20mm with a maximum height of 0.85mm, it supports standard reflow soldering processes.

Crystals Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with target circuit parameters. Confirm that the required frequency tolerance and load capacitance align with the design specifications before finalizing procurement orders. Check current availability status as lead times may vary based on production schedules.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency is required with strict size constraints. Ensure the application circuit provides the specified 18 pF load capacitance to achieve the stated accuracy. Consider the 50 Ohm ESR value for oscillator drive level calculations to prevent over-driving the crystal.

Crystals Part Context

This part belongs to the 405 Series of surface mount crystals from CTS-Frequency Controls. The series offers various frequencies and packages optimized for high-volume manufacturing. The 'I' suffix typically denotes industrial temperature range performance, while 'D' indicates specific packaging or handling characteristics defined by the manufacturer.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz 18pF SMD crystals from CTS such as the 405C35D25M00000 variant, provided temperature ranges match requirements. Cross-manufacturer replacements must verify identical frequency, load capacitance, ESR, and physical dimensions.
