Tantalum Capacitors

Tantalum capacitors, also known as Tantalum electrolytic capacitors, are capacitors which use tantalum as the anode material. Tantalum capacitors are widely used in numerous applications. They are typically used in power supplies, noise filters, decoupling applications, and timing circuits. Mica capacitors, aluminum electrolytic capacitors and ceramic capacitors may also be substituted for tantalum capacitors in various circuit applications. While these components are sometimes usedas alternatives, they are typically less reliable than tantalum capacitors. The topic of this article is TRJB156M010RRJ, a type of tantalum capacitors, and their application field and working principle.

TRJB156M010RRJ

TRJB156M010RRJ is a high-temperature solid electrolytic tantalum capacitor with a Molded Case Package (MCP). It is also called MicroTan SMD capacitor. The MCP of TRJB156M010RRJ is a molded-in epoxy housing that eliminates the need for external insulation. The two-part housing incorporates internal terminalmetallization. The non-polar capacitor has a capacitance value of 10µF and an ESR value of 0.07Ω. It isoperated in a temperature range between -25°C to +125°C. The small form factor of TRJB156M010RRJ, along with its high volumetric efficiency, makes it suitable for space-constrained applications such aslaptops and tablets.

Application Field and Working Principle

TRJB156M010RRJ is typically used in the automotive industry and high-end consumer electronics.In the automotive industry, these capacitors are used in engine control modules, air bag systems, anti-lock brake systems, traction control systems, passive entry systems, and sound systems. In consumer electronics, they are used in TVs, cell phones, MP3 players, camcorders, and wearable electronics.

Generally speaking, the construction of Tantalum Electrolytic Capacitor consists of two electrodes sandwiched between an oxide layer. The oxide layer acts as an electrically insulating layer. The electrode terminals are connected to the leads which are externally connected to the circuitry. The oxide layer is formed when a positive voltage is applied to the positive terminal of the capacitor.The positive terminal is then called the anode, and the negative terminal is called the cathode. The oxide layer, along with the anode and cathode, form the capacitance. The capacitance is all the energy that can be stored in the capacitor, which is directly related to the applied voltage.The release of energy is done by allowing an electric current to flow across the cathode and anode.

Due to their low equivalent series resistance (ESR) and high volumetric efficiency, Tantalumcapacitors are seen as a good alternative to other types of capacitors such as aluminum electrolytic orceramic capacitors. They are also smaller in size as compared to other components and can be usedin applications that have limited space available. Furthermore, they have a good lifespan and operateat high temperatures.

In conclusion, TRJB156M010RRJ has numerous key features which make it attractive in the market.It is small in size and is constructed using a high-temperature solid electrolytic and a Molded Case Package. Due to its low ESR and superior volumetric efficiency, it is suitable for use in various applicationswhich are space-constrained such as automotive systems, consumer electronics, and high-end equipment in general.
