Tantalum capacitors are among the most commonly used components in the electronics industry. They are ideal for applications where electrolytic capacitors are impractical due to size or thermal constraints, such as in portable applications or with small form factor components.

The M39003/01-5636H is a commercially available high capacitance and performance polymer hybrid tantalum capacitor, which is popular in consumer and industrial applications. The device is a high-performance, low-impedance, plug-in replacement for aluminum electrolytic capacitors. The low profile, SMD packaged device is available in voltage ratings up to 35V, with two capacitor options which offer capacitance ratings from 4.7 uF to 56 uF.

The use of a tantalum capacitor is advantageous in certain applications due to its low impedance and low ESR (Equivalent Series Resistance). This makes it an ideal choice for applications that require high capacitance, high ripple current handling and/or high surge current capability in a space-constrained package.

A significant feature of this type of capacitor is the fact that it uses a solid electrolyte. This means that it does not require a reservoir of liquid electrolyte, which eliminates the need for frequent maintenance and prevents leaks and other related problems.

The M39003/01-5636H construction provides enhanced performance compared to the conventional wet or electrolytic tantalum capacitors. The device is a hybrid capacitor which uses a tantalum layer as the dielectric, and an organic polymer material as the cathode. This combination provides a robust device capable of withstanding higher operating temperatures and higher ripple current loads than a traditional wet tantalum capacitor.

The device also provides a high energy density, which means that it can store more energy for its size than other types of capacitors. This makes it ideal for applications where space is at a premium. The device also has better temperature stability and low ESR, making it suitable for use in high-frequency switching power supplies and wide temperature applications.

The working principle of the M39003/01-5636H is similar to that of other tantalum capacitors. It consists of two foil plates of opposite polarity connecting each other within an insulating layer. The tantalum foil forms the dielectric layer, while an organic polymer material is used as the electron acceptor or cathode material. When connected to a voltage source, the applied voltage produces an electric field between the two foil plates, causing electrons to flow through the organic cathode material. The resulting charge separation creates an electrostatic field which stores electric energy.

The distinctive features of the M39003/01-5636H make it suitable for use in a variety of applications. It is widely used in consumer electronics, such as smartphones, tablets, and laptops. Its low-profile package and high capacitance make it suitable for use in applications which require a high degree of efficiency in a small package. It is also a popular choice for hobbies and automotive applications. The solid tantalum construction makes the device especially suitable for use in temperature-sensitive applications and in applications which require high reliability and low ESR.
