TAP685K025SRW

Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are polarized capacitor components that use tantalum and an oxide layer as the electrodes, and are typically small, cylindrical components. These capacitors are designed to store electrical energy, and vary in size and shape to accommodate different areas of use. TAP685K025SRW is one of the tantalum capacitor components that stands out in its application field and working principle.

Application Field

Tantalum capacitors are typically used in commercial, industrial and military sectors. They are more rugged and temperature-stable than aluminum electrolytic capacitors, but higher valued and more costly. TAP685K025SRW is suitable for applications that require low voltage and an operating environment with temperatures ranging from -55 degrees Celsius to 125 degrees Celsius. Common applications for TAP685K025SRW include power supply filters, clock circuits, pulse input circuits, and memories in audio equipment, motor commutation circuits, telecommunication equipment, and aerospace applications.

Working Principle

Tantalum capacitors use a crystalline layer of tantalum as the cathode. The anode is made of a porous tantalum powder that is compacted with electrolytic manganese dioxide, which acts as the electrolyte. The electrolyte is usually in the form of a liquid, but it can also be in solid form. When a voltage is applied across the capacitor, it stores electrons in the electrolyte and the anode of the capacitor, the capacitance of the electrical charge increases. TAP685K025SRW has a high capacitance of 680uF and a low equivalent series resistance that allow its use in high-frequency circuits.

Conclusion

Tantalum capacitors are a type of polarized capacitor, and are suited for applications where performance requirements exceed those of other aluminum electrolytic capacitors. TAP685K025SRW is specifically tailored for use in various sectors due to its resistance to high temperatures, its high capacitance, and its low equivalent series resistance. With its unique properties, TAP685K025SRW is a preferred choice for power supply filters, clock circuits, pulse input circuits, telecommunication equipment, and aerospace applications.
