Tantalum capacitors are widely used in today’s electronic components, and the M39003/09-0336/HSD is an example of such capacitors. In this blog, the application field and working principle of the M39003/09-0336/HSD will be discussed.

The M39003/09-0336/HSD is a 2-terminal, axial leaded series of industrial grade, hermetically sealed tantalum capacitors. With a voltage rating of 10 WVDC (128 VDC max) and an optional temperature coefficient rating of +50 ppm/°C (cold-rolled steel), the M39003/09-0336/HSD capacitors are suitable for various high voltage applications. It also has a dielectric of tantalum, which is made available in three different anode configurations (a, b or c).

It has a maximum temperature range of -55 °C to +125°C and a wide capacitance range of 10μF ,100μF, 1000μF. Due to its high voltage rating and stability under temperature cycling, M39003/09-0336/HSD capacitors are ideal for use in power supplies, voltage converters, ignition systems, audio power amplifiers, and any system requiring high reliability.

The M39003/09-0336/HSD capacitors operate on the principle of electrical double layer capacitance (EDLC). This type of capacitor uses an electrolyte medium to saturate the anode material with positive ions and the cathode material with negative ions. When a voltage is applied to the two terminals of the M39003/09-0336/HSD capacitor, the ions on the anode move towards the cathode and the ions on the cathode move towards the anode. The ions create a charge that modifies or stores voltage, resulting in capacitance.

An important feature of the electrolyte is that it allows ions to move freely between the anode and cathode, while providing an isolating barrier that prevents direct current from flowing between the contacts. This feature is essential for the functioning of the electrolytic capacitor. In the case of the M39003/09-0336/HSD capacitors, the anode material is tantalum and the electrolyte is a hermetically sealed non-volatile liquid.

The tantalum anode of the M39003/09-0336/HSD capacitors is typically made from sintered tantalum powder. The unique porous structure of the sintered tantalum anode allows for a wide variety of electrolyte solutions to be used. The amount of capacitance is determined by the amount of electrolyte used and the area of the sintered material. The capacitance of the M39003/09-0336/HSD is also affected by the temperature, as the electrolyte material has a specific heat capacity.

Due to its capacitance and high voltage rating, the M39003/09-0336/HSD series of tantalum capacitors are an excellent choice for many high voltage applications. The wide variety of anode configurations and sizes make them a reliable and flexible choice for engineers. The hermetically sealed structure and non-volatile electrolyte make them suitable for use in harsh environments. The unique design provides for a robust, high voltage capacitor that is suitable for many applications.
