Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor. The main feature of these devices is their large capacitance in a very small package, which makes them ideal for use in compact electronic circuits. They are popular for use in computers, communications equipment, medical devices, and OEM applications. The tantalum capacitors are classified into two main categories: Solid Tantalum Capacitors and Manganese Dioxide (MnO2) Tantalum Capacitors.

M39003/01-2660/HSD capacitors are a type of solid tantalum capacitors which feature a non-magnetic, ultra-high-frequency shield, referred to as "NEMSHield". This shielding increases the Schottky diode switching speed and improves EMI/RFI noise suppression. It also reduces the amount of heat generated by the capacitor. The capacitors are made of layers of tantalum oxide and have an anode of solid tantalum powder, a cathode of MnO2 and an electrolyte of aqueous sodium hydroxide solution.

The M39003/01-2660/HSD capacitor is ideal for use in high-frequency switching circuits, power supplies, and general-purpose filtering applications. The capacitors are available in a wide variety of sizes and capacitance values, making them suitable for many different types of electronic designs. They are typically used in applications requiring high speed and low power consumption. The capacitors are also suitable for high-temperature applications.

The working principle of an electrolytic capacitor is based on the electrical double layer effect. When two electrodes are placed in an electrolyte solution, ions from the electrolyte solution will quickly attach to the surfaces of the electrodes. This creates an electrical double layer at each electrode-electrolyte interface. As a result, a potential difference is created, which causes charges to accumulate on each electrode surface. The net electrostatic effect of the accumulated charges produces a capacitance.

In the case of the M39003/01-2660/HSD capacitor, the anode is made of solid tantalum powder and a cathode of MnO2. The two electrodes form the dielectric layer which creates the capacitance. The NEMSHield provides additional shielding to reduce the amount of heat generated by the capacitor. As electrical current passes through the capacitor, the charge accumulates on the electrodes, creating a potential difference which generates the capacitance.

The main advantages of M39003/01-2660/HSD capacitors are their small size and high capacitance. They are ideal for high-speed switching circuits, power supplies, and general-purpose filtering applications. They are also suitable for high-temperature applications. Additionally, the NEMSHield increases the Schottky diode switching speed and reduces EMI/RFI noise suppression.
