Overview
The KEMET FLLCC300A055I1 is a feed-through capacitor designed for electromagnetic interference suppression. It features a capacitance of 0.5 µF and a DC voltage rating of 750 V. The component utilizes a coaxial structure with a central conductor, providing low impedance paths for high-frequency noise while maintaining signal integrity. It is engineered for robust performance in demanding industrial environments.
Feature Summary
- Coaxial feed-through design for effective EMI/RFI filtering
- High DC voltage rating suitable for power line applications
- Robust construction for industrial-grade reliability
Applications
- Industrial motor drives
- Power supply input filtering
- Control panel EMI suppression
Procurement Notes
Verify the specific suffix 'I1' against the official KEMET datasheet to confirm terminal configuration and mounting style. Ensure the 750V DC rating aligns with system requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by project specifications.
Selection Notes
Select this component when high capacitance and high voltage handling are required in a compact coaxial form factor. Consider the physical dimensions and mounting constraints relative to the enclosure design. Evaluate the frequency response characteristics against the specific noise spectrum present in the application environment.
Part Context
This part belongs to the KEMET FLLCC series of feed-through capacitors. These components are distinct from standard MLCCs or film capacitors due to their integrated shielding and feed-through architecture. They are commonly used where space is limited and high-frequency attenuation is critical.
Replacement Considerations
Check for direct substitutes within the FLLCC series with matching capacitance and voltage ratings. Verify mechanical compatibility including hole spacing and overall length. Ensure electrical parameters such as leakage current and insulation resistance meet or exceed original specifications.
