Tantalum capacitors are a type of electrolytic capacitor, with little or no equivalent comparison. This article will discuss the application fields and working principles of the M39003/01-7055, specifically.

Tantalum capacitors are encased in a metal oxide cathode, individual of solid tantalum capacitors, which has an anode of tantalum powder. Taking the form of a cylindrical shape, and ranging from one to several millimeters in diameter, these capacitors have excellent performance when used in low frequency applications. Other note-worthy properties of tantalum capacitors include low leakage current, high capacitance, and long-term stability.

The M39003/01-7055 model, in particular, is a hermetically sealed, cylindrical tantalum capacitor and is used for surface mounting and conformal coating. It primarily comprises of two-in-one Tantalum Stainless Steel (TSS) technology and has a salt spray rating of over 500 hours with up to 105°C threshold. This model is available mainly in two different case sizes, both with diameters of 2.5mm and 5mm respectively.

In terms of application fields, the M39003/01-7055 model is primarily used in automotive, consumer industry, and other electronic products that are highly reliable, hermetically sealed and long-term stability. Examples include audible and visible warning systems, automotive airbags, brakes, and instrument clusters. In addition, these capacitors are also useful for filtering and buffering in audio applications.

In terms of its working principle, the M39003/01-7055 capacitor acts as a flow-through device that allows D.C. current to pass without hindrance. This allows the capacitor to store energy, which can then be released as a surge current, which in turn can be used to power a circuit when needed. This is done by splitting the Tantalum Oxide (TaO) anode, while the cathode is metallic and is sealed on the other end. The electrolyte completes the circuit to allow the current to flow, which is stored and subsequently released to power the circuit.

Tantalum capacitors are widely used in automotive, consumer, and portable devices for their extraordinary power and capacity. Of these, the M39003/01-7055 model is notable due to its hermetically sealed cylindrical shape and its ability to survive extreme temperatures and long-term stability. Its application fields and working principle have been discussed in detail in this article.
