ESD-FPD-40

Overview

The KEMET ESD-FPD-40 is a split-core ferrite cable core designed for flat cables. It utilizes Ni-Zn ferromagnetic material to provide electromagnetic interference suppression. The component features an inner dimension of 56.00mm width by 2.00mm height, allowing it to accommodate specific flat cable profiles. It operates effectively up to a maximum frequency of 300MHz. The unit is constructed for free-hanging mounting and does not require permanent attachment to the cable or chassis.

Feature Summary

• Split-core design enables installation on existing cables without disconnection
• Ni-Zn ferrite composition provides effective high-frequency noise attenuation
• Specifically engineered geometry matches standard flat cable dimensions

Applications

• Electromagnetic interference suppression for flat ribbon cables
• Signal integrity enhancement in data transmission lines
• Noise reduction in electronic equipment internal wiring

Procurement Notes

Verify that the target flat cable dimensions strictly match the core's inner aperture of 56.00mm by 2.00mm to ensure proper fit and magnetic coupling. Confirm that the operating frequency range of the application falls within the component's effective spectrum up to 300MHz. Ensure the Ni-Zn material type aligns with the required impedance characteristics for the specific noise frequencies present in the system.

Selection Notes

Select this component when retrofitting shielding onto flat cables where continuous loop closure is necessary. The split-core architecture is essential for applications requiring post-assembly modification. Consider the physical size constraints of the enclosure to accommodate the outer dimensions of the core. Validate that the Ni-Zn material properties are suitable for the dominant noise frequencies encountered in the specific circuit environment.

Part Context

This component belongs to KEMET's line of ferrite cable cores, which are passive devices used for common-mode noise suppression. Unlike solid toroids, split cores allow for non-invasive integration into existing harnesses. These components are critical for meeting electromagnetic compatibility standards in dense electronic assemblies where flat cabling is prevalent.

Replacement Considerations

Ensure any substitute part maintains the same inner dimensions (56mm x 2mm) and uses Ni-Zn material for comparable high-frequency performance. Verify that the replacement also offers a split-core mechanism for identical installation flexibility.
