Filter F4804A is a fully compatible replacement for F4804, with improved electrical and thermal characteristics. Unlike most available off-the-shelf filter modules, the F4804A, in addition to common mode noise reduction components, is 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. F4804A filter is designed specifically for distributed power solutions in conjunction with dc-dc converters. Low profile and small size (only 0.75 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 4 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 MCD10059 Rev. 1.0 Page 2 of 41 www.power-one.com
