Tantalum Capacitors: The M39003/09-0247/TR Application Field and Working Principle

The M39003/09-0247/TR series of tantalum capacitors have become an important device in many modern digital and micro-electronic designs due to its small size and low cost. As a member of the tantalum capacitor family, the M39003/09-0247/TR series are well known for providing relatively large capacitance values in a similar sized package compared to other capacitors. In addition, it is very reliable and provides low leakage current and excellent thermal stability which makes them excellent choices for applications that require high reliability.Tantalum capacitors are constructed of four main components: a tantalum anode, a cathode lead, an electrolyte and a capacitor case. The anode and cathode lead are made of tantalum, a ductile, corrosion-resistant metal, that acts as the mechanism that holds electrons during the electrical states of a capacitor. The electrolyte, a type of liquid solder, is used to create a space between the two ends. A case is then used to secure the components inside.When current is passed through a tantalum capacitor, the oxidized electrolytic material inside the capacitor is changed, and this process is known as "capacitance". This change in electrical field occurring in the capacitor results in a charge that can be measured by the millivolts, volts, or capacitance value of the capacitor. This charge is typically used in electronic circuits to store or transfer energy. Tantalum capacitors are used in many electronic circuits, including power supplies, processors, and even audio amplifiers in order to store and transfer the necessary energy by providing the suitable voltage and current to the device. As previously mentioned, the M39003/09-0247/TR series of capacitors provides low leakage current and excellent thermal stability which makes them a very reliable option for applications where these features are required. Additionally, the small size and low cost make them an attractive option for many applications. The main technical specifications of the M39003/09-0247/TR series of capacitors include a capacitance range from 0.1 μF to 220 μF, and a rated voltage up to 25 volts. Other characteristics include a high insulation resistance (>1,000 megohms at 25V, up to100V), a great pulse discharge current (in the order of 2.2A/µF), a high dielectric strength (2.67Vmax. breakdown voltage for 10%), and a -55°C ~ +125°C temperature range.The M39003/09-0247/TR series of capacitors have a wide range of applications in medical, military and industrial applications, such as in power supplies, motors, UPS systems, automotive electronics, mobile phones and more. Its non-polarized structure makes it suitable for alternating currents (AC), while its high insulation resistance and low leakage current makes them suitable for low frequency AC and DC applications. In addition, because these capacitors are able to maintain reliable and stable operations, they are ideal for use in precision circuits such as in voltage converters, test equipment, and frequency converters.In conclusion, the M39003/09-0247/TR series of tantalum capacitors offer a wide range of applications due to their small size, reliable performance, and low cost. Their ability to provide a high insulation resistance and low leakage current makes them suitable for a variety of AC and DC applications. Furthermore, their high dielectric strength and wide temperature range provide excellent stability for use in precision circuits. As such, they are quickly becoming an important device in many modern digital and micro-electronic designs.
