Tantalum capacitors are the most popular technology used to store electrical energy. They are small, lightweight and have the ability to hold relatively large amounts of electrical energy given their size. The TPSE336K025R020 is a high-performance, long-life electrolytic capacitor from AVX. It provides electrochemical energy storage and utilizes two different layers of tantalum powder to achieve a high capacitance and low series resistance.

The TPSE336K025R020 is designed for use in a wide range of applications, from general-purpose circuits to high-frequency switching power supplies. It is a surface-mount tantalum capacitor that provides high operating temperature capabilities and high reliability in a compact footprint. Its reliable performance and small size make it an ideal choice for designs that require extreme miniaturization, such as wearable electronics and medical devices.

The working principle of this type of capacitor is based on the physical properties of tantalum, which is an aqueous, highly conductive material. Essentially, a layer of tantalum powder is sandwiched between two porous ceramic layers. As an electric current passes through the capacitor, the tantalum powder forms an electrical field that is concentrated near the ceramic layers. This field causes a dielectric layer to form between the ceramic layers, which allows the capacitor to store electrical charge. Since the field is concentrated near the ceramic layers, the area of the capacitor’s plates is much smaller than it would be with a non-porous material. This reduces the size and weight of the capacitor and makes it more efficient.

The TPSE336K025R020 has a capacitance of 0.33 μF, and a voltage rating of 16 VDC. Its temperature range is -55°C to +125°C, with a maximum capacitance change of ±5% between -55°C and +20°C. It is made using a patented sintered anode technology that offers lower ESR than equivalent devices. The low ESR means that the capacitor can handle high-frequency switching power supplies without causing EMI issues.

The TPSE336K025R020 is perfect for applications that require high reliability, low ESR and operating temperature capabilities. It is RoHS compliant, lead-free and halogen free, and offers the best compromise of performance and cost for certain applications. It offers a reliable storage solution for expensive, high-end electronics such as medical implants, as well as for everyday electronics such as cellular phones, cameras, and audio equipment.
