Feedthru Filters – W2F4/W3F4 Series EMI Filtering, Broadband Filtering, LCD Filtering GENERAL DESCRIPTION W3F4 Series Available in a 4-Element 0508 and 0612 Feedthru Array package, AVX’s line of Feedthrus is an ideal choice for EMI suppression, broadband I/O filtering, LCD filtering and Vcc power line conditioning. The unique construction of the Feedthru capacitor provides low parallel inductance and offers excellent decoupling capability for all high di/dt environments and provides significant noise reduction in digital circuits up to 5 GHz. A range of filtering characteristics is available. The Feedthru Array contains four elements with a common ground connection, making it an ideal choice for multi-line designs. Additional benefits of the multi-element array package are reduced placement costs, reduced component counts and PCB space savings. Feedthru filters can be used to meet IEC, MIL-STD-461E, FCC, and SAE radiated and conducted emission requirements. 0612 FREQUENCY CHARACTERISTICS Part Number Roll Off Frequency Center Frequency 10 db Point 20 db Range W3F41A2208AT 270 MHz 2640 MHz 970 MHz 1780 MHz 3500 MHz W3F41A4708AT 65 MHz 2000 MHz 185 MHz 600 MHz 3400 MHz W3F41A1018AT 65 MHz 2030 MHz 185 MHz 560 MHz 3500 MHz W3F45C2218AT 35 MHz 1885 MHz 120 MHz 470 MHz 3300 MHz W3F45C4718AT 20 MHz 1860 MHz 60 MHz 220 MHz 3500 MHz W2F43A2208AT 208 MHz 4750 MHz 616 MHz 1407 MHz 7300 MHz W2F43A4708AT 110 MHz 2750 MHz 330 MHz 900 MHz 4600 MHz W2F43A1018AT 60 MHz 1300 MHz 179 MHz 501 MHz 7200 MHz CAPACITOR VALUES & PERFORMANCE CHARACTERISTICS Part Number Typical Capacitance Insulation Resistance Temperature Characteristics W3F41A2208AT 22pF > 1000 M_ NP0 W3F41A4708AT 47pF > 1000 M_ NP0 W3F41A1018AT 100pF > 1000 M_ NP0 W3F45C2218AT 220pF > 1000 M_ X7R W3F45C4718AT 470pF > 1000 M_ X7R W2F43A2208AT 22pF > 1000 M_ NP0 W2F43A4708AT 47pF > 1000 M_ NP0 W2F43A1018AT 100pF > 1000 M_ NP0 CASE SIZE & VOLTAGE RATINGS Part Number W3F41A2208AT W3F41A4708AT W3F41A1018AT Case Size Current Rating DC Resistance Voltage Rating 0612 300 mA < 0.6_ 100 V W3F45C2218AT W3F45C4718AT 0612 300 mA < 0.6_ 50 V W2F43A2208AT W2F43A4708AT W2F43A1018AT 0508 50 mA < 3.0_ 25 V 9 Feedthru Filters — W2F4 / W3F4 Series EMI Filtering, Broadband Filtering, LCD Filtering W3F41A2208ATSS21 CURVES Curves W3F41A2208AT 21 Preliminary AVX W3F41A2208AT Typical S21 Preliminary AVX W3F41A2208AT TYPICAL S21 0 -10 dB -20 -30 1 2 -40 3 4 -50 0.1 1 1 Preliminary AVX W3F41A2208AT Typical Far-side XTALK Elements 1 -
