Tantalum capacitors have become crucial components in the design of power electronic circuits, consumer electronics and aerospace applications. Tantalum capacitors provide a number of advantages over traditional ceramic capacitors and aluminum electrolytic capacitors. They have excellent capacitance-to-volume ratios and offer good dielectric strength and excellent performance when used in specialized applications. The F720G157KRC is a tantalum capacitor that is ideal for a variety of applications and offers very reliable performance.

Design

The F720G157KRC is a molded SMT (Surface Mount Technology) capacitor with two leads. The capacitor has a leadless surface mountable design that ensures reliability and conforms to the RoHS (Restriction on Hazardous Substances) Directive. The capacitor has a voltage rating of 15V and can store up to 977μF of energy in its 2.8 x 2.0 mm case dimensions.

Working Principle

Tantalum capacitors work on a principle known as electrolytic capacitance, which is similar to a battery. They are polarized capacitors because they have an anode and a cathode, and they can only store energy in a single direction. The anode of the capacitor is made of tantalum and is sputtered with a coating of insulating oxide. The oxide layer forms a dielectric between the anode and the cathode, allowing it to store energy in the form of electrons.

To charge the capacitor, an electric current is passed through the anode and the oxide layer, and the electrons are pulled from the anode and stored on the cathode. When the capacitor is discharged, the electrons are released and travel back to the anode. This process is repeated, allowing for energy to be stored and discharged with the slightest of currents.

Application Field

The F720G157KRC tantalum capacitor is an ideal choice for use in power supplies, DC-DC conversion, and high-temperature automotive applications. It is designed to handle power surges and can be used in audio systems, as well as, voltage conversion circuits. Its low ESR and high capacitance levels make it a great choice for power supply design.

The F720G157KRC is also ideal for use in high-temperature and long-term applications as it is rated for operation up to +105°C and has a shelf life of 2000 hours at +85°C. The capacitor is also RoHS compliant and can be used in medical and communications OEMs.

Tantalum capacitors are a highly reliable and cost-effective choice for use in a variety of circuits. They have the ability to store large amounts of energy in a small form factor and provide excellent capacitance-to-volume ratios. The F720G157KRC is a highly reliable and cost-effective choice for use in medium voltage and high-temperature applications.
