Polymer tantalum capacitors now offer reduced ESR

Polymer tantalum capacitors now offer reduced ESR
AVX's F38 series of miniature, undertab, conductive polymer tantalum capacitors now feature a significantly reduced ESR for several ratings. The series, which already offered one of the smallest and highest CV polymer tantalum capacitors in the industry (0603 capacitors with an ultralow profile of 0.9mm and 6.3V/47μF ratings) now offers the lowest ESR small case size polymer capacitors available on the market, says AVX.
