Tantalum Capacitors

M39003/09-0340/HSD Application Field and Working PrincipleTantalum capacitors are one of the most widely used types of capacitors in commercial applications due to their high capacitance, small size, light weight, and stability over temperature, current, and time. The M39003/09-0340/HSD is a high-speed surface-mount tantalum capacitor that is among the most popular variants of this type of capacitor.The M39003/09-0340/HSD capacitors have a focused application field that involves high-frequency filtering, smoothing, and coupling in power conversion systems, high-frequency communication systems, and aerospace systems. In these applications, the M39003/09-0340/HSD capacitors offer rapid switching and reduced EMI or RFI interference. The M39003/09-0340/HSD capacitors have a simple working principle. It stores an electric charge between two non-conductive dielectric materials. When a voltage is applied across the capacitor, a current flows in the circuit and the capacitor gets charged. The charge that is stored in the capacitor can be dissipated once the voltage is removed. The amount of charge that a capacitor stores depends on the capacitance, which is the ratio of the amount of charge stored for each unit of potential difference (voltage) applied between the two dielectric materials. The M39003/09-0340/HSD capacitors have a dielectric of moist tantalum and a construction of an etched foil dielectric element that is hermetically encapsulated. This construction makes M39003/09-0340/HSD capacitors suitable for high-voltage use. The electrolytic solutions of the M39003/09-0340/HSD capacitors also have low-ESR characteristics that can offer improved filtering, providing superior thermal stability. The M39003/09-0340/HSD capacitor behaves differently than a ceramic or film capacitor in terms of the voltage reversal. In the case of ceramic or film capacitors, reversed DC voltage can cause a dramatic reduction in their capacitance. However, the capacitance of M39003/09-0340/HSD capacitors is less prone to the effects of reverse voltage and is therefore more reliable in applications where there is a possibility of reverse voltage being applied. In addition, M39003/09-0340/HSD capacitors also feature a high degree of reliability and durability. They are considered reliable for more than 85% of the rate voltage after 1,000 hours of operation. Additionally, their reliability is also highly resistant to temperature changes, since their capacitance increases with an increase in temperature and then stabilizes at a particular temperature. Overall, the M39003/09-0340/HSD capacitors are a highly reliable, stable, and durable type of tantalum capacitor that are most extensively used in high-frequency communication systems, aerospace systems, power conversion systems, and related applications. With a simple working principle and superior performance, they offer significant advantages over other types of capacitors, making them one of the most versatile solutions for various applications.
