AVX’s patented Q-Process was developed to replace the Weibull Reliability Assessment as the industry standard for tantalum capacitors due to its tendency to burn-in potentially unstable units. In use since 2013, the Q-Process, which has enhanced screening imbedding in it, effectively removes components that may experience parametric shifts through customer processing or display instability through life testing, ensures stable and normalized DCL distribution, and provides reliability level verification through life testing to a minimum of 0.1% per 1,000 hours with a 90% confidence level.

Currently available in three case sizes (0603, 0805, and 1411), three rated voltages (4V, 6V, and 10V), three capacitance tolerances (±5%, ±10%, and ±20%), and with capacitance values spanning 2.2μF to 68μF, the series is rated for use in operating temperatures ranging from -55°C to +125°C.

At present, 0603 size components are available rated for 2.2μF to 4.7μF and all three voltages, 0805 components are available rated for 6.8μF to 22μF and all three voltages, and 1411 components are available rated for 33μF to 68μF and two voltages: 6V and 10V.

TBC Series HRC6000 medical implantable grade capacitors are also available with one of three termination finishes: solder fused, gold-plated, and 100% matte tin, the latter two of which are lead-free compatible and RoHS compliant. Lead time for the series is 12 weeks, and components can be shipped in bulk, on 7" tape and reel, or in waffle packaging.
