TCR Professional Series capacitors exhibit stable electrical parameters

AVX introduces new tantalum capacitor series for high power DC/DC converters

AVX Corporation, a leading manufacturer of passive components and interconnect solutions, has introduced the new TCR Professional Series tantalum chip capacitors with conductive polymer electrodes. Designed for use in high power DC/DC converters employed in telecommunications, industrial, and avionics applications that demand high reliability and long lifetime performance, TCR Professional Series capacitors are subjected to AVX's maverick part control Q-Process with statistical screening and process control enhancement to ensure the removal of any components that may experience parametric shifts through customer processing or display instability through life testing. As such, the series exhibits high standard reliability of fewer than 0.5% failures per 1,000 hours at 85°C and rated voltage with 0.1Ω/V series impedance.

Featuring a robust mechanical design with conductive polymer electrodes that offer a benign failure mode under recommended use conditions, TCR Professional Series capacitors exhibit stable electrical parameters, including low ESR and DCL (0.1CV standard, 0.05CV on select codes), over long operational lifespans at temperatures ranging from -55°C to +105°C. TCR Series capacitors are also compact, surface mountable, compatible with 3x reflow at 265°C, pick-and-place ready, and RoHS compliant.

Currently, two TCR Professional Series capacitors have been released: a 10V, 68µF part and a 16V, 47µF part, both of which exhibit a ±20% capacitance tolerance and a DCL of 0.1CV, and are housed in an EIA 2917 case with a height of 2.90mm. TCR Professional Series tantalum chip capacitors in three additional case sizes (EIA 1210, 2312, and 2917 with a height of 4.10mm), five additional voltages (20, 25, 35, 50, and 63), and capacitance values spanning 0.47µF to 100µF are currently under development, as are parts available with a DCL of 0.05CV.

“The new TCR Professional Series will provide power electronics engineers in the telecommunications, industrial, and aviation industries with a wide array of robust tantalum chip capacitors carefully screened for quality and proven to exhibit high reliability and stable electrical parameters, including low ESR and DCL, over long operational lifetimes,” said Mitch Weaver, Member of Technical Staff at AVX.

TCR Professional Series capacitors are packaged with pure tin terminations on 7” or 13” reels; however, tin/lead terminations are available upon request. Lead time for the series is 12 weeks.
