The Extreme Environment DC Filters are specifically designed for high vibration and/or high altitude applications. This class of HPR is available in the metric series of filters with 55Amp, 140Amp, and 400Amp ratings. Enhanced E class (Identified by “E” at the end of the P/N)
The levels here are in addition to the limits for the Metric Series in the succeeding table.
