Tantalum Capacitors are probably the most numerous capacitor type found in today’s electronics. The M39003/01-8076H is a small package version of a precise fixed value tantalum capacitor, with a value between 2.2 and 22µF, and a voltage rating between 6.3V and 30V. It is particularly useful for power supplies, timing and tuning networks, buffers and sample-and-hold operations.

One of the most important advantages of tantalum capacitors is their small size. This makes it possible to use them in densely packed circuit boards. Furthermore, they are low-cost, stable, and reliable. They have a greater resistance to temperature fluctuations and thermal shock than other capacitor types, making them ideal for use in military and other critical applications.

Tantalum capacitors can be further divided into two categories: wet and solid electrolytic capacitors. The M39003/01-8076H belongs to the solid electrolytic type. The capacitance value of this type of capacitor is formed by the ratio between the area of the tantalum anode and the number of turns in the dielectric layer separator. The dielectric consistency as well as the capacitance value of tantalum capacitors can be further increased by the embedded organic polymer.

In the case of an M39003/01-8076H, an electrolyte is used as a dielectric material. The electrolyte is typically a mixture of potash and organic solvent, which when combined, produces an electrolyte that is both a good conductor and dielectric. The electrolyte is then injected into the anode of the tantalum capacitor. As the electrical current passes through the capacitor, an electric field is activated that charges the anode and the dielectric. This electric field produces a positive charge in the anode and a negative charge in the dielectric, which then creates a capacitance property.

The anode of the M39003/01-8076H capacitor is made of tantalum, which is a low temperature, high conductivity material. The tantalum anode has an extremely thin dielectric layer that is composed of a ceramic material. This ceramic material is isolated from the silicon oxide layer of the substrate, which helps protect the capacitor from electrical shorts or leakage. This isolation also prevents the quiescent current from flowing to the surrounding circuitry.

To prevent electrical shorts from occurring in the capacitor, tantalum capacitors utilize an anode safety vent. This vent allows any buildup of heat or electrical charge to be safely released from within the capacitor before it reaches a damaging level. In order for this vent to be effective, the vent must be short-circuited immediately after it has vented off the charge. This is done to prevent further shorting from occurring within the capacitor.

Tantalum capacitors are used in a variety of applications, including power supplies, high-frequency oscillators, data converters, and signal filtering. The M39003/01-8076H is a popular choice for these types of applications because of its high capacitance, low leakage, and high temperature stability. Its small size also allows it to be used in densely packed circuit boards.

In conclusion, the M39003/01-8076H is a precise fixed value tantalum capacitor that is particularly useful for power supplies, timing and tuning networks, buffers and sample-and-hold operations. Its small size makes it ideal for use in densely packed circuit boards. Additionally, it is low cost, stable, and reliable while having a greater resistance to temperature fluctuations and thermal shock than other capacitor types. Its most important feature is the anode safety vent, which prevents electrical shorts and leakage from occurring in the capacitor.
