    x5r vs x7r

    In datasheet: All capacitors are ceramic X5R or X7R.
    What is full description of 'X5R'?

    x7r vs x5r

    Hi, It is telling you which dielectric material is used for the capacitor, and what performance you can expect.

    Paul.

    Re: what does 'Ceramic X5R or X7R' mean?

    Hi,
    X means minimum temperature range -55degC
    5 means maximum temperature range +85degC
    R means percentage of capacitance change permitted +/- 15%

    X means minimum temperature range -55degC
    7 means maximum temperature range +125degC
    R means percentage of capacitance change permitted +/- 15%
