435F300Y5IET

Crystals Overview

The CTS-Frequency Controls 435F300Y5IET is a surface mount crystal oscillator operating at a fundamental frequency of 30.0 MHz. It features a load capacitance of 20 pF and a frequency tolerance of ±25 ppm with stability of ±50 ppm across the operating temperature range of -40°C to +85°C. The component utilizes a 4-SMD, no-lead package measuring 5.00 mm in length, 3.20 mm in width, and a maximum height of 1.10 mm. Its equivalent series resistance (ESR) is specified at 40 Ohms.

Crystals Feature Summary

• Surface mount design for automated assembly
• Fundamental mode operation
• Compliant with RoHS 3 standards

Crystals Applications

• General purpose timing circuits
• Microcontroller clock sources
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific frequency tolerance requirement of ±25 ppm against system specifications, as this part differs from standard ±30 ppm variants. Confirm that the 20 pF load capacitance matches the oscillator circuit design. Ensure the 4-SMD footprint dimensions align with the PCB layout constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 30 MHz fundamental frequency is required with tight tolerance specifications. The 40 Ohm ESR value supports stable oscillation in standard parallel resonant circuits. Consider the -40°C to +85°C industrial temperature range for environmental suitability compared to commercial grade alternatives.

Crystals Part Context

This part belongs to the CTS 435 series of surface mount crystals. It is distinct from other series such as the 405 or TS models which offer different frequencies, packages, or electrical characteristics. The 435 series provides a standardized form factor for high-frequency applications requiring precise timing control.

Crystals Replacement Considerations

Public confirmed substitute: 435F30035IET. Verify compatibility regarding the ±30 ppm tolerance difference compared to the ±25 ppm of the primary model.
