Tantalum Capacitors

Tantalum capacitors are a kind of electrochemical, solid-state capacitors, featuring high electrical performance, low leakage current, long service life, and reliable performance. They are made of tantalum and various dielectrics (insulating materials). Tantalum capacitors are widely used in the automotive, telecommunications, consumer electronics, medical, automotive, defense, and space industries.

The M39003/03-4036 is a type of tantalum capacitor. These capacitors offer excellent performance capabilities, such as low equivalent series resistance (ESR), low leakage current, and an extended temperature range. The M39003/03-4036 capacitors are used in commercial and military applications to filter high frequency ripple and decouple power supply lines.

Application Field

The M39003/03-4036 tantalum capacitors are designed to provide primary filtering, bypass filtering, and high-frequency decoupling in military and commercial applications. They are used to filter high frequency (switching) ripple noise from power supply lines, reduce electrical noise, and improve power supply stability. They are commonly used in AC-DC, DC-DC, and AC-AC converters, and other high-frequency applications.

Working Principle

The M39003/03-4036 has a dielectric layer made of tantalum that acts as a dielectric between two capacitor plates. The capacitor plates are made of a material that has a high corrosion resistance. The plates are connected to two electrical terminals. The plates are separated by a dielectric layer that does not allow the flow of current between the plates, except in one direction. In other words, the dielectric material acts as an insulating barrier. When a voltage is applied across the capacitor, charge accumulates on the plates, thereby increasing the capacitance of the device.

The characteristic that makes the M39003/03-4036 tantalum capacitor unique is the dielectric material itself. Tantalum is a highly stable dielectric material that offers low dielectric losses and very high dielectric strength. In other words, the dielectric material is able to retain its electrical properties even in high temperatures. This makes the M39003/03-4036 tantalum capacitors highly reliable and long-lasting.

Pros & Cons

The M39003/03-4036 tantalum capacitors are exceptionally durable and reliable. They have extremely low ESR values and are able to tolerate higher frequencies than most other types of capacitors. In addition, the dielectric used in the capacitor has a much higher dielectric constant than most other types of capacitors, which results in higher capacitance per unit volume and lower electrical leakage. The low ESR and high capacitance values, coupled with a low self-heating rate, make the M39003/03-4036 tantalum capacitors highly efficient and reliable.

However, these capacitors have their drawbacks as well. They are highly sensitive to temperature and need to be handled with care when soldering. Furthermore, the dielectric has a very high capacitance value, which means that the capacitor is less suitable for applications that require low capacitance values. Lastly, these capacitors are only available in a limited range of sizes, which might be limiting for applications that require different capacitance values.

Conclusion

The M39003/03-4036 tantalum capacitors are highly reliable, long-lasting, and efficient, making them an ideal choice for military and commercial applications that require high frequency filtering, bypass filtering, and/or high-frequency decoupling. However, they are only available in a limited range of sizes, and are highly sensitive to temperature which makes them more difficult to work with. Nonetheless, the many advantages mean that these capacitors offer exceptional performance for their intended applications.
