Taiyo Yuden USA Inc. (Schaumberg, IL) announced its new CF Series of surface-mount multilayer ceramic capacitors (MLCCs). Designed for high-frequency filtering applications, the CF Series MLCCs provide an alternative to SMD plastic film capacitors for designers of consumer audio equipment and PLL mobile-phone circuits. The CF Series’ extremely low ESR also makes them suitable for high-speed microprocessor applications.
The CF Series is currently available in 0603 (1nF, 1.5nF, 2.2nF, 3.3nF), 0805 (4.7nF, 6.8nF, 10nF, 22nF) and 1206 (47nF, 100nF) case sizes. The capacitors are claimed to provide excellent component reliability and have stronger thermal shock and mechanical stress-withstand capabilities. The company maintains that the capacitors provide superior dc bias characteristics. The breakdown voltage for the series is 780V. Additional capacitance values are now under development and will be available in the second half of 2001.
The CF Series dielectric material is composed of a cubic (CaZrO3) molecular structure that is claimed to offer better temperature stability and lower ESR than tetragonal BaTiO3-based chemistries used in Taiyo Yuden’s series of high-capacitance capacitors. Cost reduction and reliability are enhanced by the use of base metal (nickel) throughout, for both the internal and external electrodes.
Pricing for the CF Series starts at $0.08 each in 100,000-piece lots. They are currently available with delivery in 8 to 10 weeks ARO.
