435F28623CKT

Crystals Overview

The CTS-Frequency Controls 435F28623CKT is a fundamental mode MHz crystal designed for surface mount applications. It operates at a nominal frequency of 28.63636 MHz with a load capacitance of 8 pF and an equivalent series resistance of 40 ohms. The component features a frequency stability of ±25 ppm and a tolerance of ±25 ppm. Housed in a compact 2-pad SMD package measuring 5.0mm by 3.2mm, it supports a standard operating temperature range of -20°C to +70°C.

Crystals Feature Summary

• Fundamental resonance mode operation
• Compact 2-pad surface mount footprint
• Low equivalent series resistance design

Crystals Applications

• Oscillator circuits requiring precise timing
• Microcontroller clock sources
• Communication module frequency references

Crystals Procurement Notes

Verify the specific load capacitance requirement of your oscillator circuit matches the 8 pF specification. Confirm that the 40 ohm ESR is compatible with the driving strength of your host device. Ensure the 5.0mm x 3.2mm package dimensions fit within the allocated PCB space constraints.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required rather than an overtone type. The 8 pF load capacitance dictates compatibility with specific circuit designs. Consider the ±25 ppm stability limits against system timing requirements. The surface mount form factor is suitable for automated assembly processes.

Crystals Part Context

This part belongs to the CTS 435 series of frequency control products. It is distinct from other series like the 405 or 402 which may feature different pin counts or package sizes. The manufacturer provides datasheets detailing electrical characteristics and soldering recommendations for this specific family.

Crystals Replacement Considerations

Direct substitutes must match the 28.63636 MHz frequency, 8 pF load capacitance, and 40 ohm ESR. Verify that alternative components maintain the same 2-pad SMD package dimensions and fundamental mode operation to ensure circuit compatibility.
