Noise has been measured in a number of biased solid tantalum capacitors at frequencies down to 0.01 Hz. Thenoise current was found to have a 1/f power spectrum, and the amplitude varied with the bias voltage with a lawin the range 1st to 4th power. There was a large difference in amplitudes between different capacitors of thesame type
