FLLDU040A445I0 Description

Short technical summary and product information.

The KEMET FLLDU040A445I0 is a power feed-through filter from the FLLDU series, designed for general-purpose EMI suppression in high-current applications. It is rated for 40A at 40°C and supports 250VAC or 440VDC operation across 50-60Hz line frequencies. The filter uses an LC topology with 2x2.2µF capacitance and provides typical insertion loss of 18dB at 10kHz, 32dB at 100kHz, 68dB at 1MHz, and 100dB from 10MHz to 1GHz.

 

This filter features a rugged resin-sealed construction with axial threaded terminals for bolt-mount installation. It operates over a temperature range of -40°C to 85°C with a climate category of 40/085/56. The part is RoHS3 compliant and has an MSL of 1 (unlimited). It is suitable for use in screened rooms, medical equipment, power supplies, high-frequency welding equipment, and telecom systems.
