LF-3300

Power Line Filter Modules Overview

The KEMET LF-3300 is a power line filter and RFI filter designed for electromagnetic interference suppression. It operates within a frequency range of 10 kHz to 1 MHz, providing attenuation greater than 60 dB at 150 kHz and greater than 40 dB at 1 MHz. The component supports a maximum current of 3 A and withstands a surge voltage up to 2.5 kV. Rated for a maximum operating temperature of 85 °C, it features a compact form factor measuring 79 mm in length, 38 mm in width, and 25 mm in height, with a mass of approximately 100 g.

Power Line Filter Modules Feature Summary

Power Line Filter Modules Procurement Notes

Verify that the specific order matches the exact part number LF-3300 to ensure correct electrical characteristics. Confirm compliance requirements such as RoHS status against project specifications. Check datasheet ratings for current and voltage limits before integration. Ensure physical dimensions fit the intended enclosure space. Validate supplier documentation for authenticity and traceability.

Power Line Filter Modules Selection Notes

Select this component when application requires robust RFI attenuation between 10 kHz and 1 MHz. Consider the 3 A current rating and 2.5 kV surge capability for circuit protection needs. Evaluate thermal constraints to ensure operation remains below the 85 °C maximum limit. Compare physical dimensions against available board or chassis space. Assess cost-effectiveness relative to performance requirements compared to alternative filter solutions.

Power Line Filter Modules Part Context

The LF-3300 belongs to KEMET's portfolio of passive components focused on electromagnetic compatibility. It functions as a specialized filter rather than a standard capacitor or resistor. This series addresses noise reduction challenges in power distribution networks. The design prioritizes reliability in environments subject to significant electrical interference.
