EMI Filters 

**FLLDH & FLLDU Power Feed-Throu h Filters g** 

## **Overview** 

This wide range of feed-through filters provide excellent EMI attenuation up to GHz frequency levels. They are an economical alternative to dedicated filter units, where multiple input or output power lines require suppression. Due to the high capacitance values of these filters, protective measures (e.g. protective earthing) in accordance with equipment/system regulations are required. 

## **Applications** 

Particularly suitable for use in screened rooms, medical equipment,  power supplies, high frequency welding equipment, and telecom systems. 

- Current ratings from 16A to 300A 

- Excellent attenuation up-to 1GHz 

- Wide choice of performance options 

- Rugged resin sealed construction 

- Lock-nut or flange-mounting
