Tantalum capacitors are an important class of capacitors in Electronics and Electrical Engineering, and offer a variety of performance advantages over other capacitor types. The TAWD685K035R0600 series of Tantalum capacitors are constructed with a tantalum anode and cathode, and offer great performance in high temperature, high voltage, and low ESR (Equivalent Series Resistance) applications in comparison to other capacitor types.

Specifically, the TAWD685K035R0600 series of Tantalum capacitors offer low ESR in the range of 1-2 ohms, a high volumetric efficiency (small size for large values of capacitance) and a very robust temperature range of -55 to +125 degrees Celsius. This temperature rating is very important for high temperature applications that require temperatures up to and over 125 degrees Celsius, such as in automobile engine control systems or other markets with high temperature requirements. The TAWD series also have a very fast settling time, steady capacitance value over a wide range of temperatures, and high self-healing characteristics.

In terms of physical aspects, the TAWD series of Tantalum capacitors are polarised, which means that they operate off of DC voltages without needing extra components. Further, the capacitors are constructed with a ceramic core enclosing the anode and a rolled tin/lead cathode; the component is also coated with an epoxy resin to provide extra protection. TAWD capacitors can also withstand harsh environments, including high temperatures and moisture, which is an advantage when compared to electrolytic and film capacitors.

To understand how the TAWD series of Tantalum capacitors work, it’s important to understand the working principle of capacitors in general. This section will provide a generalised look at how capacitors work and the principles applied to TAWD series as well. All capacitors have two basic parts: the anode and the cathode. The anode is positively charged and the cathode is negatively charged. When a voltage is applied to the capacitor, positive charges in the anode and negative charges in the cathode attract each other and form a layer of electrons between them. This provides the capacitance of the component, which is measured in Farads.

The capacitance of the TAWD series of Tantalum capacitors is determined by the size of the dielectric (ceramic core) between the two electrodes, which in turn is determined by the physical size of the component. The smaller the component, the higher the capacitance; however, this is usually balanced with a lower operating temperature range. The TAWD series of Tantalum capacitors offer a good balance of high capacitance and high temperature rating.

Because the dielectric of a capacitor has some resistance, the capacitor also has a value of Equivalent Series Resistance (ESR). The ESR of a capacitor is determined by the shape and size of the capacitor’s dielectric, as well as its capacitance and temperature rating. TAWD series capacitors have very low ESR compared to other types of capacitors, which makes them ideal for high voltage and high temperature applications.

Tantalum capacitors are an excellent choice for applications requiring high capacitance and high temperature rating. The TAWD685K035R0600 series of Tantalum capacitors offers great performance in these types of applications and is an excellent choice for a range of markets, from automotive to computing, and everything in between. The low ESR, high volumetric efficiency, and robust temperature range of the TAWD series make them a great choice for high voltage and high temperature applications.
