Tantalum capacitors are one of the most common types of capacitors available on the market today. Among that, the M39003/09-2051 series are especially renowned for their high performance characteristics, high reliability, and good stability. The M39003/09-2051 is a molded-case, miniature tantalum electrolytic capacitor that is rugged and reliable, making it well-suited for many different applications.

These capacitors are self-healing, meaning that if the capacitor ever gets shorted out, it will open up its internal resistance and not blow up in the process. They provide very high capacitance values in small but reliable packages and are especially advantageous in military and aerospace applications where vibration, humidity, temperature, and other harsh environmental conditions can prove to be damaging to conventional capacitors.

The M39003/09-2051 series capacitors are ideal for telecommunications, industrial, medical, and commercial applications as well. They are commonly used to provide filtering, power-supply bypassing, decoupling, and charge-pump functions. With their low ESR and ESL characteristics, these capacitors can quickly store and release necessary ripple currents and provide stable power supply filtration.

Internally, the M39003/09-2051 series capacitors consist of a tantalum anode body, a dielectric layer composed of tantalum pentoxide, and their lead-out wires are sealed with epoxy resin. The capacitor body is hermetically sealed, providing a rugged frame for the internal components withstanding environmental and mechanical conditions. This ensures that the capacitor has the highest reliability for its system\'s proper operation and reduces mechanical risks.

The working principle of the M39003/09-2051 series is based on the same principle as other capacitors. When the capacitor is connected to a power source, electrons are drawn from the electrical source and onto the plates, thus creating an electric charge on the two plates. The dielectric layer between the two plates prevents a full-fledged current from flowing, instead creating a capacitance that stores the charge and provides electrical power.

The resulting capacitance of the M39003/09-2051 series is expressed in pico-farads and they are capable of withstanding high voltage and wide range of temperatures as well. These capacitors can handle hundreds of volts and temperatures up to 125°C, meaning that they can provide reliable and consistent power over long periods of time.

In summary, the M39003/09-2051 series are a reliable, high-performance, and durable tantalum electrolytic capacitors for all sorts of general-purpose applications. Their low ESR and ESL characteristics, high capacitance values, and ability to withstand high voltages and temperatures make them an ideal choice for military and aerospace applications as well. The capacitor’s rugged body also ensures that these capacitors are reliable and long-lasting, making them well suited for a wide array of applications.
