The M39003/03-0127/HSD capacitor is one such type of tantalum capacitor, offering dependable performance in various applications. This article explores the application field and working principle of this capacitor.

Capacitance Ratings

The M39003/03-0127/HSD capacitor features a capacitance range from 0.22µF to 22µF in a single configuration. This makes it a good choice for a wide range of applications, such as audio, power management, medical, and consumer electronics. In terms of equivalent series resistance (ESR), the capacitor can range from as low as 0.2Ω to 1Ω, depending on the capacitance rating.

Working Principle

The M39003/03-0127/HSD capacitor has a tantalum-based construction that offers various advantages over traditional aluminum electrolytic capacitors. It consists of a dielectric layer, an inhomogeneous compressive layer, and a cathode containing a salt bridge. The dielectric layer is composed of an oxide material that is both non-polar and highly stable. In addition, the cathode contains an electrolyte paste that flows around an anode, providing the capacitor with improved contact and stability.

When a voltage is applied across the capacitor, the resulting current will create an electrical field between the anode and the cathode, which then causes the dielectric layer to become polarized. This polarization reduces the resistance of the dielectric layer and increases the capacitance of the capacitor. The electrolyte paste flowing around the anode also offers excellent electrical contact and minimized sequence resistance. As a result, the M39003/03-0127/HSD capacitor has excellent voltage sensing and charge storage capabilities.
