M39003/01-6038

Tantalum capacitors are electrochemical components that use a tantalum pentoxide (Ta2O5) layer as the dielectric and a tantalum metal layer as the electrode. M39003/01-6038 tantalum capacitors are popular components for electronic applications, offering a higher capacitance and higher volumetric efficiency than other types of capacitors, as well as a much lower ESR (equivalent series resistance).

The M39003/01-6038 tantalum capacitor belongs to the “small case size” category. These components are typically specialized parts that require much smaller case sizes than that of a traditional tantalum capacitor. This size reduction is achieved by using a semiconductor-grade Ta2O5 layer that is initially applied in liquid form. The combination of the small physical footprint and large capacitance makes the M39003/01-6038 tantalum capacitor ideal for applications with limited space and high capacitance requirements.

M39003/01-6038 tantalum capacitors are manufactured with a “Molded” case that is significantly smaller than that of a typical tantalum capacitor. This format offers better electrical connections, improved temperature characteristics, and a lower overall profile. The internal structure of the capacitor consists of two layers of an electrolyte and an internal spacer. This allows the capacitor to have a larger capacitance than a standard Tantalum capacitor in the same size.

M39003/01-6038 tantalum capacitors are highly versatile and can be used in a variety of application fields. Commonly, they are used in military, aerospace, and medical electronics due to their reliability and temperature range capabilities. The main application fields of M39003/01-6038 can be divided in two:

Power electronics

M39003/01-6038 tantalum capacitors can be used in power electronic systems, such as switch-mode power supplies, DC/DC converters, and DC inverters. These devices need capacitors with excellent high frequency characteristics, operating temperature ranges, and reliability for dealing with the high AC ripples that occur in power electronics designs. M39003/01-6038 capacitors are able to provide superior performance in these applications.

Signal filter

Another application field of M39003/01-6038 capacitors is signal filtering. These devices are commonly used to remove high frequency noise from signals in communications systems, such as cellular base stations and Wi-Fi routers. The low ESR of the M39003/01-6038 makes them highly efficient for filtering high frequency signals, and the small size of the component allows it to be easily mounted in high-density PCBs (printed circuit boards).

Working principle

M39003/01-6038 tantalum capacitors work on the principle of “energy storage”. When a DC voltage is applied to the capacitor, electrons start to accumulate on one of the electrodes and this creates an electrostatic field around it. This field traps the electrons and stores their energy, thus creating capacitance. The value of the capacitance is determined by the materials used in the construction of the capacitor and the geometry of the device.

M39003/01-6038 tantalum capacitors have a low ESR compared to other types of capacitors, allowing them to more efficiently store energy and filter out high-frequency noise in analog circuits. In order to achieve this excellent performance, M39003/01-6038 tantalum capacitors are made with a thin film of special semiconductor grade Ta2O5. This material enables the capacitor to have relatively high capacitance in a small package.

M39003/01-6038 tantalum capacitors have proven to be extremely versatile and reliable components for a wide range of electronic applications. Their small size and high capacitance make them ideal for applications with limited space and high capacitance requirements.
