Unlike most available off-the-shelf filter modules, the F4804 contains, in addition to common mode noise reduction components, a differential LC-filter stage, which guarantees compliance with conducted noise standards in the whole frequency range from 150 kHz to 30 MHz, including fundamental switching frequency and its harmonics. Test results show headroom of 15-20 dB for conducted noise quasi-peak levels, in relation to Class B requirements; see Figs. 2-8. && TM Family DC-DC F4804 filter is designed specifically for distributed power solutions in conjunction with Q converters. Low profile and small size (only 0.75 sq. in.) in a surface mount package helps the system designer save real estate on the system board, and simplifies the layout. A single F4804 filter can be used with multiple converters, and is capable of providing up to a nominal 4 A to the converter input bus. It can provide up to 3 A at 85C ambient with no airflow. REV.

Absolute maximum voltage and maximum operating voltage are for the filter itself; check maximum rating for corresponding DC-DC converters. Filter will not be damaged with reversed input voltage. Designed primarily for 48 V applications, filter can be used with both 48 V converters (operating range from 36 V to 72 V) and 24 V converters (operating range from 18 V to 36 V). Typical filter application schematic is shown on Fig. 1. Maximum current at any ambient temperature without airflow can be calculated as Imax = [4 - 0.025*(Tamb-45)] A, with constraint Imax 4 A. Letter x denotes either T or S, i.e. filter module is loaded either with Q48T30033 through-hole or Q48S30033 surface mounted converter. Typical EMI plot for conducted emissions (with fully loaded Q48x30033 converter connected to the filter output, see schematic Fig. 1) is shown on Fig. 2. Plot was taken by independent test laboratory TUV. TUV report confirms compliance with Class B requirements according EN-55022 (CISPR-22) and FCC standards. REV.
