Tantalum Capacitors

Tantalum capacitors are a type of high-capacitance, small-sized electric double-layer capacitors. These capacitors are typically composed of two electrodes that are separated by a versatile and electrically permeable dielectric. The capacitance of these electric-double-layer capacitors can be adjusted depending on the material characteristics of the electrodes and dielectric used in their construction. The TR3D227M010C0050 is a surface mount tantalum capacitor developed by Vishay, a manufacturer of semiconductors and electrical components.

TR3D227M010C0050 Application Field and Working Principle

The TR3D227M010C0050 has been specially designed for use in demanding and space-constrained applications with a voltage rating of 10 VDC, a capacitance value of 2.2 μF, and a tolerance level of 10%. This capacitor features compact size, low profile, and electrolytic technology, making it ideal for use in the automotive, smartphone, and computer industries.

Tantalum capacitors such as the TR3D227M010C0050 are popular in circuit designs primarily due to their high capacitance-volume ratio that occurs with their construction. These capabilities allow them to be used in applications where limited space and increased capacitance are necessary. Additionally, in comparison to regular electrolytic capacitors, the density and capacitance of tantalum capacitors are much higher, making them an ideal solution for applications where size, weight, and reliability are important factors.

The ability of the TR3D227M010C0050 to provide higher capacitance from a smaller footprint is due to its internal construction. The capacitor is made up of a dielectric, two charged plates and a conductive electrolyte layer between the conductors. The dielectric creates an electric field between the plates, storing large amounts of energy in a small surface area. When current passes between the plates, charge accumulates on each plate. This charges the capacitor, providing the capacitance necessary for the circuit.

The ability of the dielectric to help store high amounts of energy is an important quality in tantalum capacitors. As a result, the internal dielectric used in the TR3D227M010C0050 is chosen based on material characteristics that can provide the desired capacitance to voltage ratio and temperature-dependent parameters. According to Vishay, the TR3D227M010C0050 utilizes a Polyethylene Terephthalate (PET) dielectric with a dissipation factor of 0.08, an insulation resistance of at least 2500 MΩ, and a working voltage of 10 VDC.

Conclusion

The TR3D227M010C0050 is a compact and high-capacitance capacitor, designed for space-constrained, demanding applications. Its small footprint and electrolytic design architecture make it an ideal solution for use in consumer electronics, automotive, and computer industries. Its internal construction helps to provide a high capacitance to voltage ratio, making it well suited for applications that require high-density capacitance. The versatile PET dielectric helps to provide temperature-dependent parameters for optimum performance.
