Tantalum capacitors are an increasingly important component in the electronic industry. In particular, those using electrolyte gel, solid tantalum electrets, and ceramic diaphragms have been developed in recent years. This article will explain the background, application field and working principle of T97D476K050N8TSC type capacitor.

Background of T97D476K050N8TSC

Tantalum capacitors are surface-mount components and are generally small in size. They are the most widely used types of surface mount capacitors and are especially suited for use in high-density circuitry lands. The T97D476K050N8TSC type is a through-hole, axial-lead, wet-slug capacitor with a maximum lead diameter of 0.5mm. It is an ideal choice for use in narrow board spaces where limited height is available.

Application Field

T97D476K050N8TSC type is used to supply a stable signal voltage, allowing for more reliable operation. It is suitable for use in automotive electronics, medical industry, PC motherboards, power supplies, and consumer electronics. It can be used to replace electrolytic capacitors in these application fields since its low equivalent series resistance (ESR) provides faster response and higher ripple current capability. It is also highly resistant to withstanding harsh environments such as high temperature, and humidity.

Working Principle

Tantalum capacitors are solid capacitors with a tantalum anode and a wet-slug cathode. They use a direct current, which passes through an electrolyte gel or solid tantalum electret to form a dielectric layer between the electrodes. This dielectric layer then acts as an insulating layer, allowing electrical current to pass through, but also blocking any DC or AC current from passing through.

The voltage drop across the capacitor is determined by the amount of charge it can store, or the “capacitance”. The capacitance is determined by multiplying the overlap area of the electrodes, the distance between them, and the dielectric constant of the material used. The voltage drop across the capacitor becomes the difference between the two terminals, and this voltage should remain constant as long as the current flowing through the capacitor is maintained.

In the case of the T97D476K050N8TSC type, the capacitor is designed to supply a stable signal voltage. The capacitance of this device is 4.7µF and can operate up to 85°C. This makes it ideal for use in temperature sensitive applications. It also has a low ESR for fast response and a cell capacitance that helps reduce noise.

Conclusion

Tantalum capacitors such as the T97D476K050N8TSC type are increasingly important components in many applications. They provide a fast response and a stable signal voltage for better performance in high density circuitry. Their small size and robust design make them ideal for use in automotive electronics, medical devices, PC motherboards, and other consumer products.
