    How to calculate emi filter component value

    Hello all,

    I want to know that how I can calculate the value of X-capacitor in order to build an EMI Differential Mode Filter.

    Kindly see the attached circuit of Isolated Full Bridge Boost Converter that I have. Inductor current is shown and just before an inductor there is a differential mode filter and I want to calculate the value of X-capacitor.

    I have determined the cutoff frequency of filter as 90KHz.

    Your help in this regard will be highly appreciated. Please help me out.

    Thanks.

      Input Filter Filling: How to Choose Components?
      by cheese007
      Recently acquired one of those silly Logisys acrylic power supplies and lucked into getting one of the "better" ones (most of an input filter, bridge rectifier instead of 4 diode treatment, OK-sized heatsinks, etc.) and wanted to fill out what I can on the board + get some decent caps on there (especially the primary side since I highly doubt the ones in there are actually 1000uf). My questions are:

      1. How do I know what components to install re: the input filter? It seem to be missing an X cap, a resistor, and a Y cap.
      2. Where can I find a good heatsink for the bridge...

      Trying to locate a capacitor for a Skytec Crossover filter
      by PennyLane
      Hi
      I'm trying to locate what i believe to be Radial Electrolytic Capacitors 100v 82uf Non-polar for a Skytec Crossover filter.
      Thanks

      Operating frequency for motherboard common mode inductor/filter
      by J_T
      I have a question - I have replaced the PSU on my own iMac Pro. However, when removing the motherboard I knocked of a 120 OHM 30% 0.3A small surface mount common mode inductor/filter (~0602 size) in the ethernet circuit near the female RJ45 port.

      The closest match I can find on Mouser is 120 OHM common mode inductor at 100MHz - my question is this frequency correct for a motherboard? The schematic for the motherboard only provides '120 OHM 30% 0.3A' and the TDK part number does not return anything in google.

      Sorry, I am not experienced hence a basic question.

      Power supply for main amp blows fuses after replacing filter caps.
      by acedogblast
      Hello I have a Marantz sr5012 that I have been repairing. After I have replaced the 2 main filter caps the 2 fuses for the power amplifier blows. The original capacitors are ELNA LAO 10,000uF 71V and the replacements are Nichicon LKS 10,000uF 80V.
      I assume a short circuit connection has occurred so I set my multimeter to measure ohms across the 2 fuse connections and both read 55 Kilo-ohms so I assume that is ok.

      I am certain that I do not have any bridges on my soldering and after probing around I do find a temporary 0 ohm reading when probing across the positive and negative...

      Pioneer VXS-D902S Reciever - Filter Capacitor Question
      by grimacelord
      Hello,

      I have a Pioneer VSX-D902S receiver that I am trying to replace the 2 large 8200uF 80V filter capacitors on.

      I have already removed the capacitors and ordered replacements, but I made a mistake in ordering. The original capacitors are Pioneer ACH1202 80v 8200uF and have 4 pins. The capacitor replacements I bought are Nichicon 80v 8200uF and only have 2 pins.

      I was wondering if I could still use my replacements even though they only have 2 pins. Obviously I'd have to extend the pins of the capacitor to allow them to reach and fit through the...
