DATASHEET PCB Filters FN 409 75 VDC Input PCB Filter Rated currents from 3 to 13 A, 75 VDC Very compact PCB-mounting design Approvals Exceptional attenuation performance High frequency noise compression FN 409 PCB filters are designed to surpress common and differential-mode noise on DC voltage lines. The suppression performance is special designed to fulfill the requirements for high frequency switching DC/DC converter modules. FN 409 filters can also be used to filter the output current of switch-mode power supplies in applications with intelligent power distribution. Features and benefits High common and differential-mode noise suppression Rated currents up to 13 A at 75 VDC Small form factor Good thermal conductance Typical applications Technical specifications Maximum continuous operating voltage Rated currents 75 V 3 to 13 A Temperature range (operation and storage) Design corresponding to -40 °C to +100 °C (40/100/21) UL 1283, CSA 22.2 No. 8 1986, IEC/EN 60939 High potential test voltage Flammability corresponding to MTBF @ 40°C/230V (Mil-HB-217F) VI1/VI2 –> GND 2000 VDC for 2 sec VI1 –> VI2 100 VDC for 2 sec UL 94 V-0 4,450,000 hours Input or output filter for high frequency DC/DC converters DC output filter for switch-mode power supplies Computer and office automation equipment Telecom equipment Input/output filter within DC power distribution networks Typical electrical schematic 2 EMC/EMI Products Schaffner Group Datasheets 2014 Filter selection table Filter Rated current @ 50 °C (40 °C) FN 409-3-02 FN 409-6.5-02 FN 409-13-02 Inductance L L1 [A] [mH] [mH] 6.5 (7) 0.5 3 (3.2) 13 (14) 2.9 0.08 0.18 Capacitance Cy @ 25 °C per path [nF] [nF] [mΩ] 4700 4.7 18 4700 4700 4.7 4.7 Typical filter attenuation Per CISPR 17; A = 50 Ω/50 Ω sym; B = 50 Ω/50 Ω asym; C = 0.1 Ω/100 Ω sym; D = 100 Ω/0.1 Ω sym 3 A types 6.5 A types 13 A types Mechanical data 3 and 6.5 A types All dimensions in mm; 1 inch = 25.4 mm Tolerances according: ISO 2768-m / EN 22768-m DC Resistance R Cx 13 A types Input/Output connections 86 -02 7.8 -02 -02 Weight [g] 30 30 47 EMC/EMI Products 3 Schaffner Group Datasheets 2014 Dimensions 3A 6.5 A 13 A B 27.9 27.9 40.6 D Ø0.8 Ø0.8 F 11.7 11.7 H 12.1 12.1 A 51 C 8.2 E 0.5 G 3.9 51 8.2 0.5 3.9 50.8 12.7 5.1 Ø1 0.5 3.8 6.4 I 31.1 31.1 17.8 K 19.05 19.05 5.08 J 4.6 4.6 Application The filters are intended to be used in DC applications per EN/IEC 60950, where no transient on the DC bus occurs. To protect the filter against transient voltages a varistor (VDR, fig. 1) or a transient diode (fig. 2) must be placed at the input side of the filter module. For protection against overcurrent place a fuse on each input lead (VI+, VI-). When AC voltage is superimposed on DC voltage, VP-P or VO-P, whichever is larger, should be maintained within the rated voltage range.
