Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are passive electronic components that are used for a variety of applications. They are used extensively in industrial, military, medical and aerospace applications due to their high capacity, low cost and excellent reliability.

M39003/09-4037/HSD Application Field and Working Principle

The M39003/09-4037/HSD is a thin-film, surface-mount tantalum capacitor that is based on a hybrid construction design. The capacitor is an ideal choice for applications requiring a small-profile capacitor with high voltage and high capacitance. It has a rated voltage of 35 volts and a capacitance value ranging from 0.1uF to 10uF.

The M39003/09-4037/HSD is one of the most widely used tantalum capacitors due to its small form factor, high voltage rating and high capacitance. It is also suitable for high frequency applications due to its low ESR (Equivalent Series Resistance). The capacitor is constructed using a ceramic base, tantalum electrochemical dielectric and a glass seal.

The working principle of the capacitor is based on the combined effects of electrical double layer formation and the phenomenon of Faraday’s laws of electrolysis. The ceramic base acts as an effective insulator and also serves as an anchor for the metal end contacts. The electrolyte between the metal end contacts and the ceramic base forms an electrical bridge that allows electrons to flow freely between the two contacts. The electric double layer formed between the two contacts during the electrical charging process stores the electrical energy which is then released during the electrical discharging process. This electrical energy is stored in the form of an electrostatic field in the electrolyte which then forms an opposing electric field to the input electrical field. This electrostatic field holds the charge for a predetermined amount of time until the charge is completely discharged.

The M39003/09-4037/HSD is designed with features that ensure stable performance over a wide range of temperatures, humidity and vibration. The capacitor offers excellent electrical noise suppression and is unaffected by temperature cycling and shock. It has a maximum ripple current rating of 5A and is suitable for applications such as DC-DC converters, line filters, power supply Decoupling, and control circuits.

In conclusion, the M39003/09-4037/HSD is an ideal choice for applications requiring high voltage and high capacitance. Its low profile, good vibration resistance, and high capacitance make it an attractive choice for use in many applications.
