capacitor
A capacitor is charged when electrons from a power source, such as a battery, flow to one of the two plates. Because the electrons cannot pass through the insulating layer, they build up on the first plate, giving it a negative charge. Electrons on the other plate are attracted to the positive terminal of the battery, causing that plate to become positively charged.

ca·pac·i·tor

(kə-păs′ĭ-tər)
A device used to store electric charge. Capacitors consist of two charged metal plates separated by an electrical insulator. The charge is supplied by connecting the plates to a source of electricity. The positive charge is stored on one of the plates, and the negative charge is stored on the other. Capacitors are used to regulate the flow of charge in electric circuits. ♦ The ability of a capacitor to store charge is called its capacitance (kə-păs′ĭ-təns). The capacitance depends on the size of the plates, the type of insulator, and the amount of space between the plates.

Due to much lower equivalent series resistance (ESR) and more benign failure mode than the incumbent MnO2-cathode technology, conductive polymer tantalum capacitors are expanding their market share in both the commercial world and military world.
Tantalum capacitors are essential in low distortion circuits and circuits that require a large bulk capacitance, and it should come as no surprise that embedded tantalum capacitors are needed to satisfy advanced designs.
Surface mount tantalum capacitors are utilized in a wide array of medical applications, ranging from handheld equipment and external devices to implantable life support systems.
However, tantalum capacitor solutions are often employed when both high vibration and high temperatures must be overcome while maintaining higher capacitance than what a ceramic capacitor can provide in smaller case sizes.
Tantalum capacitors deliver important performance advantages, but ensuring a supply of ethically sound, high-purity tantalum demands coordinated commitment across continents.
Tantalum capacitors with Mn02 cathodes are typically rated for peak temperatures of I25[degrees]C, as molded epoxy resin surfaces can degrade during long-term storage at temperatures above 125[degrees]C, which negatively affects capacitor performance.
AVX Corporation expanded its low profile, high capacitance PulseCap tantalum capacitor series to include a 3300 [micro]F/4V rated device with a low ESR of 55 m[OMEGA].
Pricing Contact manufacturer $0.25 to $0.30 in 10,000-piece quantities AVX Central Semiconductor AVX's THJ 200C SMD The CMLSH2-4LC dual pair Series SMD solid low [V.sub.F] Schottky diodes tantalum capacitor in the SOT-563 SMT case delivers 1,000 hours consist of two isolated pairs of continuous operation of 40 V, 200 mA Schottky at 200[degrees]C with diodes in a common cathode derating.
These state-of-art MIL-qualified wet tantalum capacitors are widely used in avionics applications where high performance and extreme reliability are required.
For example, the direct current leakage (DCL) specifications for commercial tantalum capacitors are quite high based on historical testing and performance data.
