• Trouble with OXLEY RFI suppression filters

    From Jean-Pierre Coulon@21:1/5 to All on Fri Apr 22 09:26:39 2022
    type FLTM/P/5000. I found a 400-ohm resistance between the lead through terminal and the ground.

    Am I the only one? Any explanations?

    The schematic shows, cap to ground, inductor. cap to ground.
    400 ohms seem very high. My explanation would be it's bad.


    ≤10nF

    Won't be there for long at 350VAC/500VDC.

    Where'd you get it from?

    I am at 5 V DC.

    Where'd you get it from?

    1: from monitoring the current while the electronics is plugged and making
    a simple calculation. I know the expected current (10 mA) with my other 10 identical setups.

    2: by measuring the resistance once unmounted with a Fluke device.

    Note that in situation 1: the current has random changes between 20 and 40
    mA. I'll research the situation with higher DC's.

    Bye
