The M39003/01-5136/HSD is rated for operation from -55°C up to +125°C, making it suitable for use in extreme temperature environments. It is also resistant to shock and vibration and has excellent shelf life.

Working Principles

The M39003/01-5136/HSD is based on the principle of metallization with tantalum anode and electrolytic cathode. A thin layer of metal is applied to either or both sides of the anode to create the electrical connection. The capacitor is then filled with an electrolytic solution and sealed.

The basic structure of a tantalum capacitor consists of a cathode made of tantalum foil, an anode in form of a solid oxide layer (Ta2O5 or MnO2), an electrolyte, and an insulating layer separating the anode and the cathode. The electrical current is conducted through a thin layer of metal that is deposited onto the anode and the cathode.

The capacitance of a tantalum capacitor is determined by the amount of electrolyte used and the thickness of the insulating layer. The higher the capacitance, the greater the amount of electrolyte can be used and the thicker the insulating layer must be. The capacitance of the M39003/01-5136/HSD ranges from 0.047 to 220µF.

The voltage rating of the capacitor depends on the voltage of the metal applied to the anode and the cathode. Typically, the voltage rating of a tantalum capacitor is twice the applied voltage. For example, a tantalum capacitor with an applied voltage of 6V will have a voltage rating of 12V.

The M39003/01-5136/HSD also has a high ripple current rating of 4.8A @ 100KHz, making it ideal for applications that require a high current ripple. It is also available in a range of case sizes and options, allowing it to be used in a variety of applications.

In summary, the M39003/01-5136/HSD is a high-reliability tantalum capacitor with a wide range of application fields. Its capacitance, voltage rating, and high ripple current rating make it suitable for use in a variety of electronic applications.
