403I35A25M00000

Crystals Overview

The CTS-Frequency Controls 403I35A25M00000 is a surface-mount MHz crystal operating at a fundamental frequency of 25 MHz. It features a load capacitance of 10pF and a frequency tolerance of ±30ppm, with stability rated at ±50ppm. The component utilizes a 4-SMD, No Lead package measuring 3.20mm x 2.50mm x 0.75mm maximum height. It exhibits an equivalent series resistance (ESR) of 60 Ohms and operates within a temperature range of -40°C to +85°C.

Crystals Feature Summary

• Fundamental mode operation for precise frequency control
• Extended industrial temperature range capability
• Compact surface-mount footprint for automated assembly

Crystals Applications

• Microcontroller clock sources
• Communication interface timing circuits
• Industrial control system oscillators

Crystals Procurement Notes

Verify the specific suffix 'A' against official CTS documentation to confirm the 10pF load capacitance specification, as standard variants in this series often utilize different load values. Ensure the selected part matches the required -40°C to +85°C operating range and RoHS compliance status before integration into the design.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency with tight ±30ppm tolerance is required in a small 3.2x2.5mm package. The 10pF load capacitance necessitates circuit design compatibility with lower capacitive loads compared to standard 18pF or 20pF crystals. Confirm that the 60 Ohm ESR aligns with the oscillator circuit's drive level requirements.

Crystals Part Context

This part belongs to the CTS 403 Series, which provides general-purpose surface-mount crystals. The 403I designation typically indicates an industrial temperature grade variant. This specific model represents a smaller footprint option within the series, suitable for space-constrained printed circuit board layouts requiring reliable timing signals.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz crystals from the same manufacturer with identical 10pF load capacitance and 3.2x2.5mm dimensions. Cross-manufacturer replacements must match the 25 MHz frequency, ±30ppm tolerance, 10pF load, and physical package size to ensure pinout and electrical compatibility.
