F2410 & F4810 Applications
Differential and Common Mode filtering for DC-DC
converters with 48 V and 24 V input:
 Telecommunications
 Data communications
 Distributed Power Solutions
Description
The F4810 and F2410 Input Filters minimize the conducted and radiated emissions generated by switch mode
DC-DC converters, and allow board designs utilizing DC-DC converters to meet stringent FCC and EN55022
Class B conducted emissions requirements.
Unlike most available off-the-shelf filter modules, the F4810 and F2410, in addition to common mode noise
reduction components, are provisioned with a differential LC-filter stage, which virtually guarantees compliance
with conducted noise standards across the 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.
F4810/F2410 filters are designed specifically for distributed power solutions in conjunction with dc-dc converters.
Low profile and small size (less than 1 sq. in.) in a surface mount package helps the designer save system board
real estate, and simplifies the layout.
A single filter can be used with multiple converters, and is capable of providing up to 10 A to the converter input
bus at 85 °C. When used as specified within this data sheet, these filters do not require airflow and/or derating at
high temperatures.
