ESD-FPL-34

Overview

The KEMET ESD-FPL-34 is a solid ferrite cable core designed for electromagnetic interference (EMI) suppression in consumer electronics. Constructed from nickel-zinc material, it provides an impedance of 60 Ω at 100 MHz with a maximum operating frequency of 300 MHz. The component features a rectangular cross-section with external dimensions of 34 mm length, 7 mm height, and 7 mm depth, accommodating an internal width of 1.5 mm. It supports up to 16 wires and operates within a temperature range of -25°C to +85°C. The part is RoHS compliant and utilizes a split-core design for easy installation around existing cables.

Feature Summary

• Solid nickel-zinc ferrite construction for effective high-frequency noise attenuation
• Split-core geometry enabling non-intrusive installation on pre-assembled wiring harnesses
• Optimized impedance characteristics for suppressing electromagnetic interference in data lines

Applications

• Consumer electronics signal line protection
• Data cable noise suppression
• Internal wiring harness filtering in electronic devices

Procurement Notes

Verify the specific impedance requirement matches the application needs, as this model offers 60 Ω at 100 MHz. Confirm that the physical dimensions fit the available space in the device enclosure. Ensure the cable bundle diameter does not exceed the internal width specification to guarantee proper magnetic coupling. Check for RoHS compliance requirements if the product is destined for regulated markets.

Selection Notes

Select this component when a low-profile, split-core solution is required for flat or bundled cables. Compare against higher impedance variants if stronger attenuation is necessary. Consider the thermal rating of +85°C to ensure stability under operational loads. Evaluate the mechanical robustness of the split-core latch mechanism if vibration resistance is critical for the end-use environment.

Part Context

This component belongs to KEMET's ESD-FPL series of flat ferrite cores. These parts are engineered specifically for compact electronic assemblies where space constraints limit the use of traditional toroidal cores. The series offers various impedance values and sizes to suit different frequency ranges and cable configurations.

Replacement Considerations

The ESD-FPL-34-15 is a documented variant within the same family, sharing similar form factors but potentially differing in specific dimensional tolerances or manufacturing batches. Verify exact dimensional compatibility before substitution.
