637 SERIES The 637 series filter is a very compact DC filter intended for use with telecommunication hardware which features a very small mechanical package. LINE LOAD The common mode insertion loss and differential loss is very good and can withstand severe vibration and shock environments. This filter has also been designed to operate with severe unbalanced current loading. Therefore, the filter will work well if one side is grounded, such as in automotive applications, as with balanced loads. Operating Voltage = _______________________48 Vdc Operating Current = __________________ 35, 50 Amps Operating Temperature Range = _________ -40 to 50°C INSERTION LOSS vs. FREQUENCY Diel.
