Tantalum capacitors play a crucial role in many electronic devices across different applications. The F981A476MSA tantalum capacitor is one of the most popular tantalum capacitor types used in applications such as energy management, digital and RF circuits, and audio devices. Here, we explore the application field and working principles of the F981A476MSA.

Applications

The F981A476MSA is a surface mount-type chip capacitor (SMD). This type of capacitor is often used in automotive, portable, and communication products due to its small size, lightweight, and low-cost. Examples of applications include:

• Energy management circuits
• TV and satellite receivers
• Mobile phones
• Computers
• Televisions
• Radar systems
• Power-on reset, baseline stability, and frequency compensation

In addition to its use in automotive, portable, and communication products, the F981A476MSA capacitor is widely used in energy management circuits. It is typically used for power-on reset and frequency compensation due to its low retail price and low conversion losses. In televisions, radio receivers, and radar systems, the F981A476MSA is used for the baseline stability of the system.

Working Principle

The F981A476MSA capacitor is a polarized, tantalum electrolytic capacitor. It consists of two metal plates separated by a dielectric material, usually tantalum oxide. The metal plates act as electrodes, and the capacitance is determined by the area of the plates, the distance between them, and the dielectric constant of the dielectric. The F981A476MSA has an operating voltage of 4.76VDC.

The F981A476MSA capacitor is used to store electric charge, and thus is often referred to as a reservoir capacitor. It is commonly used to bridge a gap in current flow in an electronic circuit, known as bypassing. This capacitor type is often used for power-on reset and frequency compensation because it has low conversion loss and can quickly react to voltage fluctuations.

When the voltage across the F981A476MSA rises, the dielectric material gets polarized and the capacitance increases. When the voltage across the F981A476MSA drops, the dielectric material gets depolarized and the capacitance decreases. Thus, the F981A476MSA capacitor is often referred to as a variable capacitor, as its capacitance varies with voltage. This characteristic is exploited in certain energy management systems.

Conclusion

The F981A476MSA is a popular surface mount-type tantalum capacitor used in various applications such as energy management, digital and RF circuits, and audio devices. Its operating voltage of 4.76 VDC makes it suitable for power-on reset and frequency compensation. The F981A476MSA capacitor is a polarized, tantalum electrolytic capacitor that is used to store electric charge and bridge a gap in current flow in an electronic circuit. It is also referred to as a variable capacitor, as its capacitance varies with voltage.
