Polymer Tantalum Capacitors claim Highest-CV Rating
AVX Corporation has extended its F38 Series with the addition of the smallest, highest CV polymer tantalum capacitors available in the industry. Packaged in a miniature 0603 (1608 metric) M case with an ultra low 0.9mm maximum profile, the new 6.3V, 47µF F38 Series capacitors nearly halve the footprint of the next smallest polymer tantalum capacitor with equivalent CV – 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. Featuring 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 to +105 degrees C, F38 Series capacitors are suited 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.
"The high CV values we were able to achieve in the new smaller and thinner 1608 M case F38 Series capacitor extend the series’ many performance benefits for further downsizing of a broad range of small, handheld electronics applications, which is a rapidly growing market segment," said Tomas Zednicek, technical marketing manager at AVX.
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 0.7mm to 0.9mm. Currently, the 0603/1608 M case capacitors are available in two voltages, 6.3V and 10V, and with capacitance values spanning 2.2µF to 47µF. The S case 0805/2012 capacitors are currently available in 6.3V and with capacitance values spanning 22µF to 47µF. However, additional F38 Series extensions, including a 6.3V, 33µF M case 0603/1608 capacitor and 4V, 100µF; 6.3V, 68µF; and 10V, 22µF S case 0805/2012 capacitors are in development. Lead time for the series is 10 to 14 weeks.
