Tantalum capacitors are an important part of the electronic component industry. Their uses span many products, such as military and consumer electronics, telecoms, medical, automotive and more. This article will provide an overview of the M39003/09-0250/TR application field and working principle.

Tantalum capacitors are surface mount devices (SMDs) that feature high capacitance values in a small footprint. This makes them suitable for high density, low-profile applications. The M39003/09-0250/TR series is a standard, miniaturized tantalum chip capacitor. It features a capacitance range from 0.47- µF up to 470 µF, with a low to medium working voltage range of up to 50 volts, depending on voltage/temperature derating. It is commonly used in power supplies, clock circuits, and audio filters.

The working principle of a tantalum capacitor revolves around the phenomenon of capacitance. This phenomenon occurs when two conductors in proximity to one another are separated with an insulator. In the case of the M39003/09-0250/TR tantalum capacitor, the two conductors of the capacitor are two layers of tantalum foil. These two layers are separated by an insulating layer of manganese oxide – also known as a dielectric layer. When an electric field is applied to the capacitor, the two layers become oppositely charged and capacitance occurs. The value of the capacitance for any given capacitor can be calculated by using the formula ΔV / Q = C, where ΔV is the voltage change, Q is the charge in coulombs, and C is the capacitance.

The capacitance value of the M39003/09-0250/TR series is obtained through a combination of high quality raw materials, careful selection of dielectric layers, and precise application of an electrical charge. These together result in a capacitance which is both reliable and accurate. The accuracy of the capacitance can be further improved by testing the capacitance at various temperatures and voltages in order to determine the temperature range of the device’s rated value. Additionally, The M39003/09-0250/TR series features a low loss factor, which prevents performance loss over the life of the device.

The M39003/09-0250/TR tantalum capacitor is an ideal solution for applications with low temperatures, tight spaces, and high performance requirements, such as medical, automotive, or military applications. In addition, its small size and high capacitance make it an ideal solution for consumer electronics applications. In summary, the M39003/09-0250/TR series is an excellent choice for applications requiring a surface mountable, low-profile, high-performance, and reliable component.
