Dear sirs，

          My customer have some questions  about the TRS3221E, Could you help to solve it? Thank you very much.

          1.what is the maximum working voltage of capacitor C1, C2 and C3 and C4?

          2.what is the nominal  voltage of capacitor C1, C2 and C3 and C4（ceramic capacitor ）？16v is enough？

    Cris,

    The voltage across C1 is close to Vcc. Same for C2. The voltage C3 sees should be within abs max range of V+ (7V). Similarly the abs max of V- applies to C4. But consider some non-ideal application scenario, it's common to use capacitors have voltage rating twice as abs max voltage. 16V rating should be a good choice. Please let me know if you have other questions.

    Regards,
