Reliability Effects with Proofing of Tantalum Capacitors
In traditional tantalum capacitors, the construction consists of a tantalum anode, Ta2O5 dielectric, and MnO2 as the cathode. The benefit of having MnO2, as the cathode, is the self-healing effect it provides. The conversion of MnO2 to a higher resistive state allows fault sites within the dielectric to be shut off from the rest of the capacitor. To mitigate problems developed during reflow, it...
متن کاملIncreasing Reliability of Smd Tantalum Capacitors in Low Impedance Applications
High dv/dt conditions in low impedance circuits using surface mount tantalum capacitors is discussed. Circuit designs utilizing low R(DS)ON MOSFETs for preventing these conditions are presented in detail.

متن کاملCharacterization of Tantalum Polymer Capacitors
Solid-electrolyte tantalum capacitors were first developed and commercially produced in the 1950s. They represented a quantum leap forward in miniaturization and reliability over existing wound-foil wet electrolytic capacitors. While the solid tantalum capacitor has dramatically improved electrical performance versus wet-electrolyte capacitors, especially at low temperatures, today’s electronic...
متن کاملTesting the effects of temperature cycling on tantalum capacitors
This study focused on the reliability testing of tantalum capacitors. The objective was to develop efficient tests to examine the effects of temperature cycling on capacitor maximum voltage. A test according to the standard JESD22-A104D overlooks the fact that temperature changes often occur while the voltage is on. Capacitors were first tested according to the standard without voltage; the tes...
متن کاملScintillation Breakdowns in Chip Tantalum Capacitors
Scintillations in solid tantalum capacitors are momentarily local breakdowns terminated by a self-healing or conversion to a high-resistive state of the manganese oxide cathode. This conversion effectively caps the defective area of the tantalum pentoxide dielectric and prevents short-circuit failures. Typically, this type of breakdown has no immediate catastrophic consequences and is often con...
