Tantalum capacitors are one of the more modern application fields and working principle technologies used in electronic components. These capacitors are composed of a special type of metal and dielectric material that provide high volume capacitance with relatively small physical sizes. CWR26HK226KBGC/TR capacitors are specifically classified as non-polarized, axial leaded tantalum capacitors and are commonly used in industrial, telecommunications, automotive, military, consumer electronics, medical, and computer applications for enhanced and reliable performance.

The physical size of the capacitors is primarily determined by the capacitance value, voltage rating, and expected performance within the applications. This model of capacitor typically comes in specific diameters; 0.3" for very low capacitance values, 0.4" for mid-range, and 0.5" for the highest. The CWR26HK226KBGC/TR capacitors provide a nominal voltage range of 6V and capacitance values ranging from 1μF to 150μF.

The internal construction of all these capacitors is made using tantalum powder, which is a remarkable material that has a very high dielectric constant. Within the housing, an anode of solid manganese dioxide is formed, while on the outside, a cathode is formed from the tantalum metal. The anode is also attached to an equally strong hermetically sealed glass to metal or ceramic package, giving these capacitors their wide range of voltage ratings and long-term stability.

This glass layer also serves another important purpose; it is an impenetrable barrier between the anode and cathode. Separating the anode from the cathode prevents the oxidation and corrosion products of the respective metals from mixing and short-circuiting the device, thus increasing the reliability of this capacitor and enabling it to function for a much longer period of time.

CWR26HK226KBGC/TR capacitors come in a wide range of options to meet the needs of most applications. These capacitors offer an extended temperature range of -55°C to +125C and a leakage current of less than 0.00000008uF. They have very low ESR (equivalent series resistance) of typically 47mohm, which is much lower than aluminum electrolytic capacitors. They also feature an improved capacitance stability, low self-discharge rates, and an extended useful life.

These capacitors are widely used in any application field that requires reliable performance in the presence of high temperatures and operating voltages. Examples of such applications include power supplies, logic circuits, consumer goods, automotive systems, sensors, and medical equipment. The conduction and dissipation of heat is also improved due to the efficient internal heat dissipation of these capacitors.

The working principle of the CWR26HK226KBGC/TR capacitors is fundamentally similar to other capacitors; it stores energy within the electric field. This is accomplished by having one plate of a capacitor store electrons while the other stores the positive charge in the form of a film. However, with this type of capacitor the dielectric is much more effective and the electrodes have a larger area in order to retain more energy.

The high surface-to-volume ratio of the electrodes coupled with the tight sealing of the anode and cathode allow more electrical charge to be stored at a given voltage. This increases the capacitance values, and thus provides enhanced performance. Furthermore, the low ESR and stable capacitance values enable these capacitors to be used under varying temperatures and voltages.

In short, CWR26HK226KBGC/TR capacitors are one of the most versatile types of modern-day capacitive technologies in the electronics industry. Their superior dielectric and diffusion properties make them suitable for a wide range of industrial, telecommunications, automotive, military, consumer electronics, medical, and computer applications. They are also very reliable and cost-effective, making them a good choice for many applications.
