402F25033CDT

Crystals Overview

The CTS-Frequency Controls 402F25033CDT is a surface-mount MHz crystal resonator operating at a fundamental frequency of 25.0000 MHz. It features a load capacitance of 18 pF and a frequency stability of ±30 ppm. The component utilizes a 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm and a maximum height of 0.45mm. It supports a wide operating temperature range from -40°C to +85°C and is RoHS compliant.

Crystals Feature Summary

• Fundamental mode operation for precise frequency generation
• Compact surface-mount design suitable for automated assembly
• Wide industrial temperature rating for environmental resilience

Crystals Applications

• Clock signal generation in digital communication systems
• Timing references for microcontroller units
• Frequency standards in portable electronic devices

Crystals Procurement Notes

Verify the specific suffix 'CDT' against the manufacturer's latest datasheet to confirm packaging and material specifications. Ensure compatibility with reflow soldering profiles defined for lead-free assemblies. Confirm that the 18pF load capacitance matches the oscillator circuit requirements before integration.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 25 MHz applications. The 18pF load capacitance must align with the host oscillator circuit design. Consider the 4-SMD footprint constraints and the -40°C to +85°C temperature range during layout planning.

Crystals Part Context

This part belongs to the 402 series of SMD crystals from CTS-Frequency Controls. It serves as a passive frequency control element, distinct from active oscillators like the 654P series. It provides the reference clock without internal amplification or output drivers.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz, 18pF, 4-SMD crystals from CTS such as the 402F25033CKT or 402F25033CDR, provided pinout and electrical parameters match exactly.
