Tantalum capacitors, or ta-caps, are electrochemical capacitors with a tantalum base and a solid electrolyte, typically manganese dioxide. Certain types of tantalum capacitors are also known as “solid electrolytic” capacitors or “solid electrolyte” capacitors due to their solid electrolyte, making them essential components in both analog and digital circuits. These capacitors are generally recognized for being small, reliable, and having a high capacitance-to-volume ratio.

TPSD226K035Y0400 is a tantalum capacitor that combines the need for small size and high capacitance with the reliability of tantalum capacitors, allowing for the use of more complex electronic designs. This capacitor is surface mountable for use in high-density surface mount designs, such as those found in cell phones and other miniaturized electronics. In addition, it has several features such as low impedance levels and low ESR (Equivalent Series Resistance) that make it an attractive choice for use in a wide variety of applications. Let’s now look at the application field and working principle of the TPSD226K035Y0400 capacitor.

Application Field

The TPSD226K035Y0400 capacitor is a generally used for power supply decoupling, blocking and by-passing, and other general purpose applications, such as voltage-sensitive devices and motor- and audio-control systems. Its low impedance, low ESR, high capacitance and stability make it an ideal choice for power filtration and ripple current suppression, providing a lower impedance path that helps to reduce and filter noise in a circuit. This is especially useful for applications where it is not possible or feasible to use higher value film and ceramic capacitors.

Its high stability makes it suited for voltage-sensitive devices such as op-amps, analogue-to-digital converters, and integrated circuits, where its capacitance can be relied upon to remain relatively constant. Its low ESR also makes it ideal for applications such as motor control systems, providing the necessary capacitance while still allowing the circuit to run at a desired frequency. Finally, its high capacitance to volume ratio makes it a popular choice for audio-control systems, where its small size allows multiple capacitors to fit onto a single board.

Working Principle

The TPSD226K035Y0400 capacitor operates on the principle of differential capacitance. In this type of capacitor, two closely spaced metal plates are separated by an electrolytic material. This material is electrically insulating, so when a voltage is applied to the plates, the electrical field that is created causes electrons to be stored in the electrolyte. The electrical charge stored in the electrolyte creates a capacitance that can be used to store electrical energy. The capacitance of the capacitor increases in proportion to the applied voltage, and can be regulated using a voltage rating.

The TPSD226K035Y0400 capacitor has a tanΘ rating of 0.035, which indicates the rate of change in capacitance as a function of voltage. This rating tells us that the capacitor can maintain a comparatively constant capacitance over a wide range of operating voltages. This type of capacitor has a low tanΘ rating and is therefore known as a “low ESR” capacitor, meaning that it has a lower equivalent series resistance than other types of capacitors.

The TPSD226K035Y0400 capacitor also has a low self-inductance rating, meaning that it has less inductance than other types of capacitors. The low self-inductance of this capacitor means that it is better suited for high frequency applications, allowing it to operate at higher frequencies without the risk of becoming saturated with current. By having a low self-inductance rating, the TPSD226K035Y0400 can be used in high-frequency circuits that require a constant charge during operation, such as pulse-width-modulation controllers.

The TPSD226K035Y0400 capacitor is a great choice for high-density surface mount designs, where its small size and high capacitance to volume ratio make it an ideal choice. Its low impedance, low ESR, and high stability make it suited to a wide variety of applications, such as power supply decoupling, blocking, and by-passing, as well as audio-control and motor-control systems. Its low self-inductance rating makes it ideal for use in high-frequency circuits, where its low impedance and low ESR make it ideal for use in various types of power-supply noise suppression.
