    #1: is there something better than a TLE2426 rail splitter?

    #2: I need a 10uf non polarized capacitor. I can use 2 electrolytics back to back of appropriate voltage (16vdc), or use 1- 10uf propylene rated at 100vdc. I like the propylene unit because it has much better tolerance, but the very high 100vdc rating concerns me. Do they need to "form" like an electrolytic does?

    Thanks,

    Joe

    10μF/100V propylene is fine.
    The 100V is the maximum allowable voltage.
    If your circuit is operating below 50V it would be just dandy.

    C'mon Joe, you know it's polite to provide a datasheet.
    If I had to tell you what's better (in this case) than a TLE2426 I'd have to see the schematic of your project.

    The poly cap is a great idea, yours simply has more quality than you need.

    After looking at the rail splitter, I can't see what use it is unless the single supply voltage is very flakey.

    It provides a low impedance virtual-ground for splitting a single supply into a dual ± supply as needed for some analog signal processing applications. You can provide a similar function with an op amp configured as a follower with two equal value resistors between the positive supply and ground of the single supply. The rail splitter is a low power device that saves a couple of external resistors.
