Tantalum capacitors are widely used in the field of electronic components. They are solid electrolyte capacitors and composed of an anode, a cathode and a solid electrolyte. This type of capacitors is named for its tantalum anode. The TAP105M050BRW is one type of tantalum capacitor manufactured by Panasonic. This article will introduce its application field and working principle in detail.

Application Field

The TAP105M050BRW is an axial type tantalum capacitor. Its packaging dimensions are 10×5×4mm. This size is suited for many heavy-duty applications. Some typical application fields include:

• Consumer electronics
• Telecommunication systems
• High-power LED systems
• Automotive components
• Industrial controllers
• Avionic systems
• Computer motherboards

The TAP105M050BRW has low ESR and low ESL characteristics, making these capacitors well suited for high-frequency applications. They also operate in wide temperature range, from -55°C to 125°C.

Working Principle

The TAP105M050BRW is a non-polarized capacitor, which offers better performance than polarized capacitors. It consists of a tantalum anode, a cathode and a solid electrolyte. The electrolyte is a solid electrolyte that acts as an insulator to prevent current from flowing between the anode and the cathode. When a voltage is applied to the capacitor, the ions in the electrolyte move toward the anode, leaving behind a wave of negative charges in the electrolyte. These negative charges are called an electric double layer.

The electric double layers act as a dielectric material between the anode and the cathode, causing the capacitor to store charge. The amount of charge stored depends on the size of the capacitor, as well as the magnitude of the applied voltage. The TAP105M050BRW has a capacitance of 50μF, allowing it to store and release a large amount of charge.

When the voltage is removed, the double layers collapse and the capacitor discharges. The discharge time and current of the TAP105M050BRW are relatively low, making it suitable for use in long-running applications.

In conclusion, the TAP105M050BRW is a type of tantalum capacitor designed for a wide range of applications. Its axial form factor makes it versatile for many heavy-duty applications. The capacitor has a capacitance of 50μF and operates in temperatures ranging from -55°C to 125°C. Its low ESR and low ESL characteristics make it well suited for high-frequency applications.
