Tantalum capacitors are a type of electrolytic capacitor that has a tantalum anode. It is primarily used in consumer electronics, especially electronic circuits, due to its ability to handle higher capacitance and higher voltage levels than other types of electrolytic capacitors.
The tantalum capacitor M39003/03-2049 is a surface mount capacitor with an advanced MnO2 cathode. It has a maximum voltage rating of 20V, a capacitance of 0.049uF, an Equivalent Series Resistance (ESR) of 5 Ohms, and is rated for a temperature of 85°C. The capacitor is RoHS compliant, Lead-free and Halogen-free.
In terms of its application field, the M39003/03-2049 is especially ideal for applications with space constraints, such as mobile phones, laptops, and tablets, due to its low profile and small footprint. It is also used in the automotive industry as an efficient, cost-effective, and long-lasting solution when power supplies and small electrical components are required, and for DC-to-DC converters. It performs well in power conditioning circuits, serves as a bypassing element in high frequency circuits, and is often used in high-frequency switching circuits.
In terms of its working principle, the tantalum capacitor works similarly to a regular electrolytic capacitor but with two main differences. The first is that the tantalum has the ability to store a higher amount of electrical charge in proportion to its volume compared to other materials, making it more suitable for applications where a higher capacitance is needed. Secondly, the MnO2 cathode increases the ability to handle higher voltages compared to standard electrolytic capacitors.
The M39003/03-2049 capacitor is constructed with tantalum powder, pressed into a shell with dielectric layers and MnO2, and a silver layer. Electrons are attracted to the silver layer, causing the dielectric layer to be polarized. As an electrical field is applied, a charge is stored on the capacitor, thus allowing current to be stored. As the electrical field is removed, the charge is gradually released, allowing the capacitor to act as a buffer.
In conclusion, the M39003/03-2049 tantalum capacitor is a small, low-profile capacitor designed for applications with varying Capacitance requirements and varied voltage levels in applications such as automotive, consumer electronics, and power supplies. It provides great performance and reliability in circuits due to its MnO2 cathode and advanced construction, which allow it to maintain its capacitance even at higher voltages.
