Introduction to Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, refer to capacitors that store electrical energy using the electrolytic process. This process creates an oxide layer on the surface of a tantalum pellet that acts as a dielectric in the capacitor. The type and thickness of this oxide layer determine the maximum allowable voltage and capacitance of the capacitor. Due to its high-density and low electrical resistance, tantalum capacitors are smaller in size and weight than aluminum electrolytic capacitors.

T95Y476M004HSSL Application Field

T95Y476M004HSSL is a type of tantalum capacitor commonly used in electronics. It has a low ESR (Equivalent Series Resistance) and a high temperature coefficient of capacitance (TCE). Its maximum allowable voltage is 6.3V, and the capacitance can range from four to seventy-six microfarads (μF). It has a low leakage current and a 10% tolerance. Thanks to its small size, the T95Y476M004HSSL is widely used in the automotive, consumer, industrial, and medical industries to regulate power, store energy, and filter noise.

T95Y476M004HSSL Working Principle

Tantalum capacitors are constructed from a tantalum pellet, a cathode strap, and a dielectric oxide layer. The tantalum pellet acts as a cathode. The cathode strap connects the pellet and the power source. When a voltage is applied across the capacitor, the pellet is charged and electrons begin to flow and deposit oxide ions onto the cathode. This electrochemical process creates an oxide layer which serves as the dielectric. The thicker the oxide layer, the higher the threshold voltage and capacitance.

Conclusion

The T95Y476M004HSSL is a type of tantalum capacitor which is widely used in the automotive, consumer, industrial, and medical industries. It stands out due to its low ESR (Equivalent Series Resistance) and high temperature coefficient of capacitance (TCE). It operates on a simple principle of creating an oxide layer on the surface of a tantalum pellet that works as the dielectricin the capacitor. The type and thickness of this oxide layer determine the maximum allowable voltage and capacitance of the capacitor.
