AVX Corp. has released its medical implantable grade tantalum capacitors that claim to provide lower DC leakage (DCL) values than any competitive offering, down to 0.0025CV or 25 per cent of typical industry limits. The TBC series HRC6000 also requires significantly less voltage de-rating than the standard 50 per cent recommendation for solid tantalum capacitors, and as low as 20 per cent for filtering and zero per cent for pacing, hold-up and charging, making them ideal for medical implantable and life support applications, noted the company.

TBC series HRC6000 capacitors

The TBC series HRC6000 needs less voltage de-rating than the standard 50 per cent recommendation for solid tantalum capacitors, making them ideal for medical implantable and life support applications.

The TBC series HRC6000 capacitors are manufactured using AVX's patented Q-Process, which 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 normalised DCL distribution, and provides reliability level verification through life testing to a minimum of 0.1 per cent per 1,000 hours with a 90 per cent confidence level.

Available in three case sizes (0603, 0805 and 1411), three rated voltages (4V, 6V and 10V), three capacitance tolerances (±5 per cent, ±10 per cent and ±20 per cent), 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.

The TBC series HRC6000 medical implantable grade capacitors are also available with one of three termination finishes: solder fused, gold-plated and 100 per cent 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 7in tape and reel, or in waffle packaging.
