data sheet february 9, 2012 FLT012A0z/FLT012A0-sz input filter modules 75vdc input voltage maximum, 12a output current maximum lineage power 5 application guidelines conducted noise on the input power lines can occur as either differential-mode or common-mode noise currents. differential-mode noise is measured between the two input lines, and is found mostly at the low frequency end of the spectrum. this noise shows up as noise at the fundamental switching frequency and its harmonics. common-mode noise is measured between the input lines and ground and is mostly broadband noise above 10 mhz. the high- frequency nature of common-mode noise is mostly due to the high-speed switching transitions of power train components. either or both types of noise may be covered in a specification, as well as a combination of the two. differential-mode noise is best attenuated using a filter composed of line-to-line capacitors (x caps) and series inductance, provided by either a discrete inductor or the leakage inductance of a common- mode choke. in addition to the differential filtering provided by the filter module, it is recommended that an electrolytic capacitor be located at the converter side of the filter to provide additional attenuation of low-frequency differential noise and to provide a low source impedance for the converter, preventing input filter oscillations and load transient induced input voltage dips. open-frame dc/dc converter modules and the older metal-cased dc/dc converter modules require slightly different filtering arrangements. the FLT012A0 series of modules are optimized for the newer open-frame series of modules, but can also be used with older metal-case modules. the main differences in filtering recommendations between the two types of modules are in common-mode filtering, as explained below. filtering open-frame dc/dc converter modules for filtering open-frame dc/dc converter modules, the recommended circuit is shown in fig. 5. in addition to the input electrolytic filter capacitor c1 (recommended value is a minimum of 100uf and approximately 1uf/w at power levels above 100w), common-mode filtering capacitors c2 and c3 should be connected between the input and outputs as shown. suitable values for common-mode capacitors c2 and c3 are in the range between 1000pf to 0.1 f are usually indicated in the dc/dc converter data sheet. these capacitors need to be rated for the isolation voltage desired between the input and output sides of the dc/dc converter module. the recommended power layout of the modules showing where the two common-mode capacitors are to be placed is shown in fig. 6. dc/dc converter module vi(-) vi(+) vo(-) vo(+) c1 c2 c3 chassis ground filter module vi(+) vi(-) figure 5. schematic diagram showing recommended connection of the FLT012A0 filter module with open-frame dc/dc converter modules . c 2 dc/dc converter v o + plan e v o ? plan e c 3 c 1 v i + v o + v o - v i - v o + v in - chassis ground input flt012 a 0 module v o - gnd v in + load figure 6. diagram showing recommended layout of the FLT012A0 filter module with open-frame dc/dc converter modules. filtering metal-case dc/dc converter modules for metal-case dc/dc converter modules with a case pin, a different filtering arrangement and layout is recommended. figure 7 shows the schematic diagram of the recommended circuit. the main difference with open-frame module is the use of an isolated shield plane located underneath the module which is connected through capacitors c2 through c5 to the input and output connections of the module. the shield plane along with the case of the module serves as a faraday shield helping reduce emi. the corresponding layout for metal-case modules is shown in fig. 8.
