AVX Corporation has added more than a dozen new high-reliability SMD tantalum capacitors to its TMJ S1gma™ Series, which exhibits the lowest DCL and twice the reliability of any commercial grade tantalum capacitors currently on the market (0.005CV standard and 0.001CV on selected codes), in addition to an impressively scant baseline part failure rate of < 0.5% per 1,000 hours at 85°C and rated voltage. Available with three levels of next-generation statistical screening and process control enhancement for applications in which exceedingly high reliability, extremely low dc leakage current (DCL), and extended battery life are paramount, the new TMJ S1gma Series capacitors are designed for use in the advanced wireless systems employed in automotive, avionics, energy harvesting, and safety applications, as well as in a variety of high-end consumer and commercial applications that demand low power consumption and extended battery life.

“TMJ S1gma Series capacitors are the capacitors of choice for professional applications that require both high reliability and extended battery life,” said Mitch Weaver, member of the technical staff at AVX. “For example, the series is especially well suited for use in tire pressure monitoring systems (TPMS), which demand both high reliability performance and stable, ultra-low DCL in order to sustain the battery over the lifetime of the system, which is typically 11 years.”

However, the series’ 0.001CV limit (restricted to certain part numbers) can only be attained through S1gma Premium screening and S1gma Pro Custom screening that employs the Q-Process. TMJ S1gma Series high-reliability SMD tantalum capacitors are currently available in six case sizes spanning 1206 to 2924, seven rated voltages spanning 6.3–50VDC, and with capacitance values spanning 0.22–680μF; although, several dozen new part numbers, including those with reduced ESR options, are currently in development.
AEC-Q200 qualified upon request, the series is rated for use in temperatures spanning -55 to +125 degrees C, and features a capacitance tolerance of ±10%. Packaged with either RoHS-compliant pure tin (Sn) plated terminations or non-RoHS tin/lead (Sn/Pb) plated terminations on 7” reels, lead time for the series is 8-12 weeks.
