Tantalum - Polymer Capacitors

Tantalum – Polymer Capacitors, also known as polymer electrolytic capacitors, have a wide variety of applications due to their relatively small size, high capacitance and low equivalent series resistance (ESR) compared to other types of capacitors. The M551B398K015AA is a tantalum – polymer capacitor commonly used in digital audio equipment and portable electronics.

M551B398K015AA Application Field and Working Principle

The M551B398K015AA is a solid tantalum – polymer capacitor that has tremendous capacitance and is designed mainly for use in audio and power supplies. The M551B398K015AA has a capacitance of 1,500 μF, a rated voltage of 25V, and a 20% tolerance (± 4). This makes it an ideal choice for applications where a high capacitance is required at lower voltages. The M551B398K015AA is also perfect for use in circuits requiring suppression of transient voltage or high frequency noise.

The M551B398K015AA uses an anodized tantalum pellet as the core material and an electrolyte to form a semiconductor capacitor. The capacitor is divided into two parts, the anode and the cathode. The anode is made from a tantalum pellet coated with a layer of nickel and a layer of manganese dioxide. The cathode is made from a silver/graphite plated aluminum foil. When a voltage is applied between the anode and the cathode, a current passes through the capacitor, releasing electrons which reduce the layer of manganese dioxide and form a dielectric layer. This dielectric layer acts as a barrier between the anode and the cathode, allowing the capacitor to store energy in a magnetic field.

The M551B398K015AA has a low equivalent series resistance (ESR), which is the amount of electrical resistance the capacitor presents when it is in operation. Low ESR capacitors can handle more power and current without overheating, making them ideal for high power applications.
