    Unrecognized component marked on the board as capacitor

    Hi All,
    I have 2 unknown (to me) components on the board - one designated as C1 the other as C160, suggesting that they are capacitors. See pictures. I have never seen capacitors like that. Both of them are shorted, none of them has any markings. The board comes from a commercial (heavy road planning equipment) GPS unit. If they are capacitors, they shouldn't be shorted, suggesting that they are faulty. Have no idea about their value. They both have something that appears as 2 blue bands. Any help will be enormously appreciated.

    They are feed-through emi filters they will check shorted from end to end, the capacitor is between the end and the center
    Maruwa CTH or TNH73 Series
    Best guess on part number TNH73R2A104S15A

        Thank you for your fast answer! Since I posted my question, I tested them further and discovered that indeed, they show as 2 capacitors with common ground in each package, both reading on the capacitor tester as 5 nF each end. I learned something new today .
