Tantalum capacitors, also known as Tantalum electrolytic capacitors and Ta capacitors, are extensively used in power supplies, voltage converters, audio amplifiers, and other areas that require small, high-quality, reliable capacitors. The T95S685M6R3LZSL is a tantalum capacitor designed for use in these exact applications.

T95S685M6R3LZSL Application Field

The T95S685M6R3LZSL is a high-performance, low-ESR capacitor designed for use in SMPS (switch mode power supplies), LED drivers, voltage converters, voltage switching power supplies, video amplifiers, and audio amplifiers. It has a maximum working voltage of 6.3V, a capacitance of 680µF, a maximum rated ripple current of 2.7A, a maximum operating temperature of 105°C, and an ESR (Equivalent Series Resistance) rating of 0.006 Ω.

T95S685M6R3LZSL Working Principle

The key component in the working principle of a tantalum capacitor is a tantalum electrolyte. This electrolyte is formed by a thin film of insoluble oxide on top of a porous layer of sintered tantalum powder. The positive and negative terminals of the capacitor are connected to opposite ends of this porous layer. During operation, current is applied to the capacitor and allowed to circulate through the tantalum powder layer. This creates a space charge between the two electrodes, where ions of the electrolyte are held in suspension, creating an electric field.

This electric field is used to create a capacitance. This capacitance is determined by the area of the electrodes and the thickness and dielectric constant of the oxide layer. In short, the T95S685M6R3LZSL is a low-ESR, high-performance tantalum capacitor designed for use in switch mode power supplies, LED drivers, and other applications that require a reliable, high-quality capacitor.

Advantages and Disadvantages

The advantages of using a T95S685M6R3LZSL capacitor are numerous. First, it has an excellent temperature rating and can be used in applications with high ambient temperatures. Its high capacitance and low ESR also make it a great choice for applications where fast transient response is required. Moreover, the capacitor offers high reliability and long-term stability, making it ideal for mission-critical applications. Finally, the capacitor’s construction ensures that it has excellent electrical performance and is resistant to vibration and shock.

The main disadvantage of a T95S685M6R3LZSL capacitor is its relatively high cost. In addition, since it is a purely electrolytic capacitor, it has a limited lifetime of around 1000 hours when operational. Additionally, because the capacitor’s construction requires a tantalum source, some manufacturers may incur additional overhead costs in sourcing and processing the materials.
