Are tantalum capacitors reliable for scintillation breakdown?

Reliability of tantalum capacitors depends on the efficiency of self-healing that restores parts after breakdown. In this work, different types of polymer and MnO2 cathode capacitors have been tested for scintillation breakdown using a constant current stress (CCS) technique modified to allow detection of amplitudes and duration of current spikes.

What is molded chip polymer tantalum capacitor?

Molded chip polymer tantalum capacitor encases the element in plastic resins, such as epoxy materials. After assembly, the capacitors are tested and inspected to assure long life and reliability. It offers excellent reliability and high stability for variety of applications in electronic devices.

What are the characteristics of tantalum chip capacitors?

Modern Surface-Mount Tantalum Chip Capacitors. The compelling characteristics of tantalum capacitors are small size, high reliability, and good parametric performance over broad ranges of frequency and temperature. As mentioned earlier, the small size of tantalum capacitors results from the porous pressed powder structure of the capacitor element.

How are tantalum capacitors made?

The pellet is next coated with graphite, followed by a layer of metallic silver, which provides a conductive surface between the pellet and the leadframe. Molded chip tantalum capacitor encases the element in plastic resins, such as epoxy materials. After assembly, the capacitors are tested and inspected to ensure long life and reliability.

What are the applications of tantalum capacitors?

These capacitors are attractive because of their high reliability, low temperature coefficient of capacitance, and high volumetric efficiency. Applications for tantalum capacitors include computers, communication system, instruments and controls for aircraft, missiles, ships and weapon systems , .

Where can I find data on a tantalum polymer capacitor?

Finished Capacitors in Carrier Tape after Leads are Trimmed and Bent around Bottom Edges (7.3mm X 4.3mm). Manufacturers of tantalum polymer capacitors often make available to their customers typical electrical performance and reliability data. Occasionally, such data can also be found in technical papers.
