  • RE: THS4551: Power Supply Decoupling

    Resolved
    Hi Robert, Thanks for the further feedback. For smaller sized COG style ceramic capacitors, they actually hold up fairly well across frequency which is why we suggest them in parallel with the larger caps. Below is an image from an AVX document where…
