Tantalum (Ta) can be found in some capacitors and is used especially in capacitors where space is important. Tantalum polymer capacitors (a type of Ta capacitor) are made of tantalum and a crystalline polymer (organic-based carbon-containing material). Due to the shape, they are sometimes referred to as ‘chip capacitors’. The T540B157K003AH8510WAFL series is one such type of tantalum polymer capacitor.

Application Field and Working Principle of T540B157K003AH8510WAFL

Tantalum polymer capacitors provide high capacitance values in a small form factor for consumer electronics. They are ideal for applications where reliable signal integrity and power delivery are necessary and the space available is limited. Common uses are in power management systems, DC/DC converters and laptop chargers, as well as other consumer electronics like LEDs and mobile phones.

The T540B157K003AH8510WAFL series can handle a wide range of working temperatures and offers exceptional ESR values at a low cost and small size. It features a high operating voltage and is highly resistant to voltage spikes and shock. The series also provides excellent energy stability and good charge retention.

The T540B157K003AH8510WAFL series provides a high capacitance rating and excellent voltage handling capabilities, making them suitable for high-power applications. The capacitance of the device is mainly determined by the electrode area and the distance between the electrodes. The surface area of the leads are greater on the surface-mounted versions of the capacitor, so the total capacitance is somewhat greater than the equivalent through-hole version.

The working principle of the device is similar to other types of capacitors. The polymer material (dielectric) is sandwiched between two electrodes, which create an electrostatic field between them (electric displacement). When a voltage is applied to the device, electrons flow from one electrode to the other. The electric field between the electrodes stores the electric charge, creating a capacitance.

The T540B157K003AH8510WAFL series of tantalum polymer capacitors offers excellent performance in high-density, low-voltage applications. These capacitors have a high capacitance rating and excellent voltage handling capabilities, making them suitable for applications where reliable power delivery is critical. With their small size and wide temperature range, they are perfect for use in consumer electronics as well as other applications where space is at a premium.
