Tantalum Capacitors

M39003/01-7181/TR Application Field and Working Principle

Tantalum capacitors, also known as Ta-cap, are amongst the most popular types of capacitors used in electronic components and devices. They are commonly found in a variety of equipment and appliances due to their ability to store electrical energy. Tantalum capacitors are composed of two metal electrodes filled with a solid electrolyte with an oxide layer in between. A tantalum capacitor is a type of capacitor that typically uses a solid tantalum (.elemental) material as its anode. The capacitors are distinguished by the solid electrolyte of a tantalum pentoxide and layer of metallic tantalum which serves as the cathode. These capacitors also use a solid solution of potassium hydroxide and other additives to create a liquid electrolyte. This liquid electrolyte is a combination of electrically charged ions that serve as a medium for electrons to flow through.The M39003/01-7181/TR series is a popular type of tantalum capacitor that is an SMD (surface mounted device) designed primarily for high temperature applications. It is a radial formed flat package capacitor with solderable terminations. The device has a voltage rating of 4.5 Volts with a capacitance range of 0.47µF to 470µF.The M39003/01-7181/TR series offers many advantages in comparison to regular tantalum capacitors. It features a wide temperature range of -55°C to 125°C which makes it the perfect choice for aerospace and automotive applications. Additionally, the series offers an improved ESR rating compared to other capacitors, as well as a high degree of heat dissipation which helps to extend its lifespan. The device is also highly resistant to shock and vibration. The working principle of the M39003/01-7181/TR series is similar to that of a regular tantalum capacitor. The device consists of two metallic surfaces separated by a solid electrolyte and an oxide layer. When a voltage is applied, an electric field is created between these two surfaces. This electric field causes a redistribution of positive and negative ions which allow electrons to flow between the electrodes. The redistribution of these charges creates a stored energy in the form of a temporary voltage difference across the capacitor. The stored energy can then be released when the voltage is reversed or when the device is disconnected from the power source. The M39003/01-7181/TR series tantalum capacitor is a versatile device that is perfect for high temperature applications. Its wide temperature range, low ESR ratings, and high level of heat dissipation make it an ideal choice for electronics in extreme environments. Additionally, the device is stable and reliable enough to be used in consumer electronics equipment.
