Tantalum-Polymer capacitors are a new breed of electronic components which offer a wide range of advantages compared to conventional components. The M551B347M030AG is a Tantalum-Polymer capacitor designed to meet the challenging environmental conditions of the Aerospace industry. It provides a highly stable and reliable source of power while maintaining an ultra-low profile and minimal weight.

In general, Tantalum-Polymer capacitors are used in the same applications as traditional tantalum or aluminum electrolytic capacitors. These include power supplies, filtering, buffering, decoupling, and voltage stabilization. The M551B347M030AG is specifically designed for use in extreme conditions such as shock, vibration, humidity, and temperature. The device has a minimum operating temperature of -55°C and a maximum operating temperature of +150°C.

The core component of the M551B347M030AG is a solid-state anode of tantalum metal coated with a conductive polymer. It is a surface-mount component with a rectangular top, making it suitable for placement in high-density areas where standard capacitors may not fit. It also has a relatively low Equivalent Series Resistance (ESR) of 0.07 ohm, meaning it has low losses and so can operate at high frequencies. The M551B347M030AG is constructed using the advanced construction technique of chip-on-chip mounting, which further reduces inductive losses and makes the device more reliable.

The working principle of the M551B347M030AG is based on the classic capacitor charging and discharging action. When a voltage is applied, the conductive material of the anode reacts with a special electrolyte in the cathode to form a conductive bridge. This bridge enables current to flow between the anode and cathode until the stored energy is released. The capacitance of the component depends on the size and shape of the anode and the electrolyte used, which dictates its ability to store energy.

In summary, the M551B347M030AG is a high-performance Tantalum-Polymer capacitor designed to meet the extreme environmental requirements of the aerospace industry. It features a low ESR and a high pulsed-current rating, meaning it can maintain a stable output voltage over a wide range of temperature and humidity. The component has an advanced construction technique and is suitable for use in high-density applications. Finally, it works on the classic capacitor charging and discharging action, allowing it to store energy and then release it quickly and reliably.
