Tantalum Capacitors
Tantalum capacitors are one of the oldest types of capacitors used in electronics and their usage dates back to the early 1960s. A tantalum capacitor is a type of electrolytic capacitor, a component of electronic circuits that stores energy. These capacitors use a buckled foil or porous anode as the dielectric material instead of the traditional mica or glass. They feature high stability, low leakage, low ESR, and good temperature characteristics. Tantalum capacitors are usually used in portable devices such as smartphones, consumer electronics, and other applications that require reliable operation.
M39003/01-2445H application field and working principle
The M39003/01-2445H is a type of tantalum capacitor manufactured by Vishay. It is a radial leaded device consisting of a tantalum pellet inside a hermetically sealed case, along with a corrosive-resistant electrolyte. These capacitors are designed for a wide range of applications, including audio circuits, power supplies, automotive electronics, and signal processing. The M39003/01-2445H features a capacitance value of 0.33μF, a voltage rating of 50V, and a capacitance tolerance of ± 10%.
The working principle of a tantalum capacitor is quite simple. They have two electrodes, one positive and one negative, that are separated by a dielectric material. When a voltage is applied across the electrodes, an electric field is created across the dielectric, which stores energy in the form of an electrostatic field. When the voltage is removed, this electric field passes current between the electrodes, thus releasing the stored energy.
The M39003/01-2445H is an ideal solution for applications where reliable and stable operation is required throughout the life of the device. The device has a high-temperature rated up to +125°C and is also available with alternative capacitance values and voltage ratings. Other features include low ESR, low DCL, and wide temperature range.
Overall, the M39003/01-2445H tantalum capacitor is an ideal solution for applications that require reliable operation. It has a wide temperature range, low ESR, and high temperature rated, making it suitable for various types of circuits. This type of capacitor is also an excellent choice for any long-term or high-power requirements in portable electronics.
