Hi all,
I've been lurking unregistered to find answers to electronics questions for awhile, but I didn't see that this one had been answered before!
I'm designing a switching power supply to power the digital logic of a racecar from the car's 12-V battery. I'm planning to use ceramic caps on the input and output, but I heard on the Amp Hour that they have problems with microphonics, especially the X7R ones.
Since there will be a lot of vibration (compared to a consumer car, ours feels like it has no suspension, and needs to drive at 60mph/100kph), I was wondering if this is serious enough to reduce the quality of the converter's output. Thanks for your help!
