Smallest and highest CV-value polymer tantalum capacitors

December 01, 2014 // By Graham Prophet
AVX has extended its F38 Series with the addition of the smallest, highest CV polymer tantalum capacitors available. Packaged in 0603 (1608 metric) M case with an ultra low 0.9-mm maximum profile, the 6.3V, 47 μF F38 Series capacitors nearly halve the footprint of the next smallest polymer tantalum capacitor with equivalent CV, which occupies a 0805 (2012 metric) case with a 1.0mm profile.

F38 Series capacitors are made from conductive polymer tantalum materials and exhibit high conductivity, low ESR, low ESL, high ripple current capabilities. With face-down terminals, which help enable low ESL and higher capacitance values in smaller case sizes, F38 Series capacitors are also robust against ignition, making them a safer alternative to comparable MnO2 type capacitors. Lead-free compatible, RoHS-compliant, and rated for use in operating temperatures spanning -55°C to +105°C, F38 Series capacitors are suitable for use in the power supply circuits of a wide variety of small electronics applications, such as the battery or power lines of smartphones, tablet PCs, handheld gaming systems, wireless modules, and hearing aids.

AVX's F38 Series polymer tantalum capacitors are offered in M case 0603 (1608 metric) and S case 0805 (2012 metric) sizes with profiles spanning 0.7 mm to 0.9 mm. Currently, the 0603/1608 M case capacitors are available in two voltages, 6.3V and 10V, and with capacitance values spanning 2.2 μF to 47 μF. The S case 0805/2012 capacitors are currently available in 6.3V and with capacitance values spanning 22 μF to 47 μF. Additional F38 Series extensions, including a 6.3V, 33 μF M case 0603/1608 capacitor and 4V, 100 μF; 6.3V, 68 μF; and 10V, 22 μF S case 0805/2012 capacitors are in development.
