Tantalum Capacitors

Tantalum capacitors are small electronic components that contain a solid tantalum electrolyte. These capacitors are well known for their high stability and low leakage current as well as their low equivalent serial resistance (ESR). They are generally used for decoupling in power supplies, filtering, and timing in integrated circuits and as bypass capacitors for transient voltage protection.Common tantalum capacitor types include polarised electrolytic and non-polarised polymer solid-state capacitors.

M39003/03-2048H Application Field and Working Principle

The M39003/03-2048H is a non-polarized, cylindrical case through-hole capacitor. It is an axial-leaded component, with its mass concentration along the longitudinal axis of the package, making it ideal for use in tight spots. It also has a high-frequency operating frequency and a low equivalent serial resistance (ESR). This makes it well suited for use as a bypass capacitor, where it can be used to reduce the effects of high-frequency noise. This capacitor can also be used as a timing capacitor in oscillator circuits for providing stable frequencies. Furthermore, it can also be used as a power supply decoupling capacitor for storing energy and reducing EMI.

Working Principle of the M39003/03-2048H capacitor

The M39003/03-2048H is composed of two electrodes, a layer of dielectric, and an electrolyte, usually Ta2O5. This combination of materials allows the capacitor to store energy in the form of an electric field between the two plates. When a voltage is applied to the electrodes, the charge stored on one plate increases while the charge on the other decreases. The electric field that is created between the electrodes is significantly reduced, similar to that of an empty capacitor. As the capacitor discharges, the electric field between the two plates is reestablished. The capacitor then becomes ready to accept a new input voltage.

The M39003/03-2048H capacitor is a highly stable and reliable device in applications that require low ESR values. Its cylindrical shape allows it to be used in tight spots. The small size and low cost make it suitable for use in consumer electronics, such as cameras, phones, and computers. Its low ESR values make it suitable for use in power supply decoupling and bypass applications, where its stability can help reduce noise and enhance the overall performance of a system. The M39003/03-2048H capacitor is a great choice for designers who want to ensure reliability, stability, and low cost in their designs.
