High-rel, low-leakage tantalum capacitors

December 11, 2013 // By Graham Prophet
Tantalum capacitors from AVX exhibit the lowest available SMD tantalum DC leakage and twice the reliability of basic commercial tantalum capacitors. Offering three levels of next-generation statistical screening & process control enhancement, the TMJ S1gma Series SMD capacitors are suitable for avionics, medical, safety system, and long-life battery operated applications

TMJ S1gma Series capacitors feature baseline part failure rate of < 0.5% per 1,000 hours at 85°C and rated volts. Available with DCL limits of 0.001CV (on selected codes) and 0.005CV, TMJ S1gma Series capacitors also exhibit the lowest DCL of any existing tantalum capacitor currently on the market, making them ideal for a variety of avionics, medical, safety system, and long-life battery operated circuit applications, such as remote wireless modules.

Statistical screening for the TMJ S1gma SMD tantalum capacitor series is available in three levels: S1gma Prime, S1gma Premium, and S1gma Pro Custom. S1gma Prime uses three electrical screenings to remove maverick parts from the distribution. S1gma Premium utilises AVX’s Q-Process in addition to the three S1gma Prime screenings to effectively identify and remove any components that may experience excessive parametric shifts or instability in operation; and S1gma Pro Custom can employ one or both of the three S1gma Prime and Q-Process screening techniques to identify and remove parts according to specific custom parameters. The series’ 0.001CV limit can only be attained via S1gma Premium and S1gma Pro Custom screening on selected codes.

TMJ S1gma Series high-reliability SMD tantalum capacitors are available in six case sizes spanning EIA 1206-2924, seven rated voltages spanning 6.3-50 VDC, and with capacitance values spanning 0.22-680 μF. Low and standard ESR value options are also available. Rated for use in temperatures ranging from -55°C to +125°C, TMJ S1gma Series capacitors feature a capacitance tolerance of ±10% .
