Accu-L® Series Thin-Film Inductors

KYOCERA AVX's Accu-L inductor is particularly suited for the telecommunications industry where there is a continuing trend towards miniaturization and increasing frequencies. The Accu-L inductor meets both the performance and tolerance requirements of present cellular frequencies, 450 MHz and 900 MHz, and of future frequencies, such as 1,700 MHz, 1,900 MHz, and 2,400 MHz. Thin-film inductors feature extreme lot-to-lot repeatability and tight tolerance. The use of very low-loss dielectric materials, silicon dioxide and silicon oxynitride, in conjunction with highly conductive electrode metals results in low ESR and high Q. These high-frequency characteristics change at a slower rate with increasing frequency than for ceramic microwave inductors. Because of the thin-film technology, the above-mentioned frequency characteristics are obtained without significant compromise of properties required for surface mounting.
