    Any Idea's of the manufacturer? Is the 10 Picofarad, or microfarad?

    Thanks,

    John

    Hello,

    The part shown is an 10 μF / 25 Volts electrolitic or tantalium capacitor.

    Hey bertus, unless you have discovered a new element, I believe it is tantalum.

    I thought as much, such as aluminum vs aluminium.

    lovely tantalum capacitors .....altho a few years back i got a few that were faulty from the off but it depends where you buy your parts from...

    sheldons, many years ago, our planet was invaded by aliens called tantalum capacitors. They were sent here to cause problems in electronic circuits by becoming solid short circuits. One of their greatest heroes was one called 4.7uF 35v that shut down a massive blow molding machine by placing a short circuit across the control circuit 5v supply, concealing itself in the rows of CMOS ics.

    These creatures sometimes failed when being soldered and would reward a high dv/dt voltage step with a short circuit.

    Thankfully, the threat has been eradicated by our brilliant engineers but beware, a few might still be around.

    Here are some that I captured and placed in the museum, never used.
