ULTRA WIDE-BAND NOISE SUPPRESSION DEVICE Ferroxfilter A Y A G E O C O M P A N Y Ferroxfilters Ferroxfilters are a powerful solution for EMI/ RFI attenuation for electronic equipment. Supplied in two sizes (0603 and 1005), they are very suitable for filtering ultra-wideband noise up to 7 GHz. When installed in series with the Vcc pin of the chip set on the circuit, ultra- wideband noise can be decoupled from the DC voltage source. No need for ground termination, which makes these devices very suitable for circuits with difficult ground. Applications • 300 KHz − 7 GHz Ultra-wideband DC decoupling • High speed image processing • High speed interface • Wireless LAN • On board DC voltage source noise Decoupling (for PLL/DAC chipsets) • RF module Noise suppression by Ferroxfilter solution Hard disk drives of company Sata Drives ; measurement courtesy RDM Technology. Measured according to CISPR class B (for domestic and residential areas), at 10 m distance in the horizontal plane. CISPR would now be in Europe : EN 61000-6-3 for2emissions in residential, commercial and light industry.
