Mil-STD-461 Compliant Filters for EMI Noise Reduction
FILTER CONNECTOR ASSEMBLIES - RF16800 SERIES

NEW PRODUCT INTRODUCTION 
Mil-STD-461 Compliant Filters for EMI Noise Reduction

RFI is introducing a new standard line of EMI filters specifically designed for reducing emissions  and lessen susceptibility for compliance to Mil-STD-461. Never before has there been a series of high performance filters that not only comply with the restrictions on Leakage Current for both 60Hz and 400Hz power systems but are characterized with Insertion Loss data directly related to the Mil-STD-461 testing methods. 
 
Insertion Loss for most filters is specified in accordance with Mil-STD-220. This test method uses a 50 ohm   source and load impedance. This is very useful information when evaluating the performance of one filter to another for Quality Control purposes. The results are accurate and repeatable. However, when you have a system that exceeds the noise limits of Mil-STD-461, and you are trying to select a filter to bring the system into compliance, Mil-STD-220 data will not accurately indicate how that filter will  perform when installed into your system.

Mil-STD-461 uses a totally different test method for measuring system noise. Current probes are used to detect the noise level of the system. This method gives very different Insertion Loss data when compared to Mil-STD-220. It is almost impossible to predict how a filter will perform in a system when all you have is Mil-STD-220 performance data.

This new series of filters from RFI is designed to be compatible with the Mil-STD-461 method of noise measurement. All the Insertion Loss data provided herein displays typical Current Probe performance. You are able make direct comparisons between filter performance and system performance. In other words, filter db reduction equals system db reduction. 

RFI is offering six different voltage and current configurations that will satisfy many applications.  All filters are true "Double L" topologies with inductive inputs at the connector. Operating temperature range is -55°  C to +85°  C without derating. Filters are designed and manufactured in accordance with all applicable sections of Mil-PRF-15733. Custom designs are also available. See Table 1 for part numbers and ratings. 

If you are currently involved in a project that requires a filter, RFI can supply a test prototype filter directly from stock.  This new series of filters are available individually or in a 6 piece filter kit.  For more information, please comtact RFI's Engineering Department.
