Tantalum-polymer capacitors are a type of capacitor used in the electronics industry whose main components are tantalum metal and a high molecular weight polymer. The M551B128M050AH is a tantalum-polymer capacitor designed for use in high-performance applications.

Overview

The M551B128M050AH is a type of Polymer Tantalum capacitors made from an anode of pure tantalum metal and a cathode of a high-molecular-weight plastic material. The main advantages of this capacitors are high capacitance values and low ESR. The capacitance range of this type of capacitor is from 10μF to 1000μF, and the voltage range is 4.5V to 16V. The ESR of this type of capacitor is typically around 1 ohm.

Application Field

The application fields of the M551B128M050AH include, but are not limited to:

  • Small-scale power Supplies
  • Automotive applications
  • Consumer and entertainment systems
  • Portable and wear-electronic devices
  • Industrial controls

Working Principle

The M551B128M050AH capacitor works by creating a charge between the anode and cathode layers. When a voltage is applied, electrical charges flow from the anode to the cathode, creating an electrical field. This electrical field is then used to store energy when the voltage ceases, and the energy can be retrieved when a voltage is reapplied.

The capacitor is constructed with an anode of pure tantalum metal and a cathode of a high molecular weight polymeric dielectric which is suspended in a heat-resistant matrix. The suspended polymeric dielectric undergoes changes in its permittivity when electrical charges are passed through it. This allows the capacitor to store large amounts of charge and release it when a voltage is reapplied.

Advantages

The M551B128M050AH has a variety of advantages over other types of capacitors. It has a higher capacitance-voltage (CV) ratio and much lower ESL than other types. It is also capable of handling higher ripple currents and frequencies and is much more resilient to temperature cycling than other types of capacitors. Additionally, the M551B128M050AH capacitors have a much higher volumetric efficiency, meaning there is more capacitance packed into a small space, making them ideal for portable and wear-electronic devices.

Disadvantages

The main disadvantage of the M551B128M050AH is the limited temperature range. The dielectric material has a temperature range of -55°C to +125°C, making it unsuitable for applications where extreme temperature ranges are needed. Additionally, the capacitor can lose some of its capacitance when operating in temperatures higher than 85°C.
