Tantalum capacitors are widely used in electronic equipment requiring high capacitance or low impedance values. The M39003/01-7043H is one such capacitor that is ideally suited for applications requiring relatively high capacitance in a limited volume and under harsh environment conditions. This capacitor combines several key features that make it an ideal choice for demanding high capacitance requirements.

The M39003/01-7043H is based on military specifications and is designed to operate reliably in temperatures ranging from -55°C to up to +125°C. Its main applications are typically found in industries that require a small, rugged device that can withstand extreme temperatures, including aerospace, automotive, and defense. It also offers high resistance to vibration, shock, and temperature. This makes it a very popular choice among military and industrial developers who require an advanced capacitance solution.

The structure of the capacitor consists of a box-like tin-plated steel case with M39003/01-7043H Tantalum electrolytic capacitors inside. This unit utilizes either a 0.001 μF capacitance value or a 0.01 μF capacitance value. The case is then filled with an inert oil and sealed for added protection. The unit packs a wide tolerance range of 20%, but is typically available with tolerances as tight as 10%. The rugged structure of this device ensures against mechanical damage during shipping. Additionally, the device is not affected by EMI or RFI, thus providing enhanced protection against electromagnetic interference.

The working principle of the M39003/01-7043H is based on the capacitance created by the electrolyte, which is proportional to the applied electric field. An increase in the electric field created between two electrodes increases the capacitance as well. This device contains two sets of special electrodes that are connected to a pair of keys. The keys are suspended over a concentric anode and cathode. When a current is applied to the device, the electric field between the two electrodes creates a capacitance that stores charge and dissipates it slowly.

The M39003/01-7043H is primarily used in high-performance power supplies and is also suitable for high frequency switching applications. Its exceptional electrical characteristics make it well suited for high capacitance requirements in a relatively compact form factor. The device also offers good resistance to temperature and humidity. It is also suitable for applications where a very low leakage current is required, such as motor control and power supply switching.

The M39003/01-7043H Tantalum capacitor is a top-of-the-line device that provides excellent performance in multiple applications. Its construction ensures reliable operation in extreme environmental conditions, while its wide capacitance range makes it suitable for a variety of applications. This device is the perfect choice for applications that require a high capacitance value in limited space.
