M39003/01-7201H

Tantalum capacitors are one of the most widely used capacitors in the world. They vary in size, construction, and applications, but all use a layer of tantalum metal coated with an oxide surface as their dielectric material. The M39003/01-7201H capacitor is a type of tantalum capacitor, designed for use in high-temperature environments.

The M39003/01-7201H is a precision, low-ESL, radial leaded-through-hole, molded tantalum capacitor. It was designed with characteristics suitable for high temperature applications. Particular points to note about this type of capacitor are its ability to withstand temperatures up to 125°C, meet the requirements of MIL-PRF-39003 and its small foot print.

The main application of the M39003/01-7201H capacitor is in military aerospace, industrial and consumer products, medical equipment, data processing equipment, and automotive components. Such applications typically require a precision capacitor with extended high-temperature range and reliable performance. Thus, for high-temperature applications the M39003/01-7201H is the preferred type of capacitor.

The M39003/01-7201H capacitor has a working principle that is similar to the other types of tantalum capacitors. It utilizes a layer of tantalum metal, coated with an electrode-dielectric layer, as its dielectric material. By applying a voltage to the electrodes, this layer\'s properties, such as capacitance and dielectric strength, change. The positive voltage attracts and collects electrons to the negative electrode\'s surface, which form a layer called the "space charge". This charge is responsible for the capacitor\'s behavior and the transfer of charge or electrical energy.

The capacitance of the M39003/01-7201H capacitor is temperature dependant and is generally higher than tantalum capacitors. This is due to its large surface area which is enabled by its radial lead construction. It also has a small ESL which contributes to its high stability and precision, as well as providing excellent low frequency capacitance characteristics. Additionally, its lead construction enables the device to be completely sealed for protection in harsh environments.

In summary, the M39003/01-7201H capacitor is a radial-lead, molded tantalum capacitor, designed to meet high-temperature aerospace, medical and automotive requirements. Its working principle is similar to other types of tantalums, but it has a higher capacitance, low ESL, and excellent low-frequency performance, due to its large surface area. As a result, it is a popular capacitor choice for high-temperature applications, due to its reliable and precise performance.
