Introduction

Tantalum capacitors, also called ta capacitors, are a type of electrochemical specialty capacitor that offers very high capacitance per unit volume over aluminum and polymer electrolytic capacitors. They are generally rectangular and are used to store and release energy at higher voltages and frequencies than most other capacitor types. The 293D105X9020A2TE3 is a type of tantalum capacitor that is commonly used in a number of applications. This article will provide an overview of the applications and working principles of the 293D105X9020A2TE3 tantalum capacitor.

Applications

Tantalum capacitors are used in a wide range of applications including medical devices, audio-visual equipment, digital communication electronics, automotive systems, and computing devices. The 293D105X9020A2TE3 is a surface-mount chip tantalum capacitor. These are most commonly used in board-level applications because of their small form factor and cost, but can also be used in industrial applications. The 293D105X9020A2TE3 has a rated voltage of 16 V, making it suitable for many high-voltage applications. It also has a relatively low ESR (Equivalent Series Resistance) of 1.5 Ohm, making it excellent for high-frequency applications. Some of the applications of the 293D105X9020A2TE3 include power supplies, high-frequency inverters and push-pull converters, and high-voltage integrated circuits.

Working Principle

Tantalum capacitors are made of a thin layer of tantalum pentoxide (Ta2O5) sandwiched between two metal electrodes, the anode and cathode. The Ta2O5 layer acts as a dielectric, storing electric charge and allowing the capacitor to hold a potential difference between the two electrodes. The amount of charge stored in the capacitor is determined by its capacitance, which is the ratio of the amount of charge stored to the potential difference between the two electrodes. The capacitance of the 293D105X9020A2TE3 is typically 105 µF, with a maximum working voltage of 16 V and a maximumcapacitance tolerance of ±20%.

Tantalum capacitors are also capable of handling high frequency signals because of their low ESL (Equivalent Series Inductance). The ESL is the inductance in the capacitor\'s circuit caused by its internal structure, which can affect the capacitor\'s ability to react to high frequency signals. The 293D105X9020A2TE3 has an ESL of less than 1 nanohenry, which is a very low value and makes the capacitor ideal for handling high-frequency signals.

Tantalum capacitors are also known for their stability and reliability. The 293D105X9020A2TE3 has an operating temperature range of –55°C to 105°C and a shelf life of 1 year at 85°C, making it suitable for long-term applications in harsh environments. This capacitor also offers high quality and performance with a low basic ESR of 1.5 Ohm and a ripple current of up to 3.2Amps.

Conclusion

The 293D105X9020A2TE3 is a type of tantalum capacitor that is used in a wide range of applications due to its small size, cost, high capacitance, high stability, and low ESL. It is most commonly used in board-level electronic applications, but can also be used in industrial applications for high-voltage and high-frequency applications. It has a maximum working voltage of 16 V and a capacitance of 105 µF, with a low ESL of less than 1 nanohenry. This capacitor also offers long-term reliability and stable performance, making it an ideal choice for many applications.
