AVX Corp. has launched a new series of high capacitance/voltage (C/V) surface-mount tantalum capacitors with a miniature and low-profile facedown design that is optimized for automotive electronics applications. The F98-AJ6 Series of resin-molded capacitors is currently available in miniature 0603 and 0805 chip sizes with maximum heights of 1.0 mm and 0.80±0.10 mm, respectively. Combined with facedown under-tab terminations, the tantalum chip capacitors deliver high capacitance, high volumetric efficiency, and high PCB assembly densities to save board space and reduce costs.
The series also features the industry’s smallest and highest-CV 0603 tantalum capacitor rated at 10 μF/10 V, said AVX. The series is qualified to AEC-Q200, lead-free compatible, and RoHS compliant. Target applications include secondary power line circuits in automotive applications including infotainment and cabin electronics systems, camera modules, and digital millers, as well as select industrial applications.
The F98-AJ6 Series capacitors packaged in 0603 sizes are rated for 4.7 μF/10 V, 4.7 μF/16 V, and 10 μF/10 V and the 0805 chips are rated for 10 μF/16 V at 85°C with a ±20% capacitance tolerance at 120 Hz. They are rated for operating temperatures from -55°C to 125°C.

The tantalum chip capacitors have undergone load humidity testing to verify their ability to meet automotive requirements for capacitance change, dissipation factor, and leakage current after 1,000 hours’ application of rated voltage in series with a 33 Ω resistor at 85°C and 85% relative humidity (RH), said AVX.
Additional values are currently in development, including 0603 chips rated for 22 μF/6.3 V and 33 μF/6.3 V and 0805 chips rated for 22 μF/10 V and 47 μF/6.3 V. Lead time for the series is 12 weeks. The capacitors are available through AVX’s distributors Digi-Key, Mouser, and Newark.
