Tantalum capacitors are polarized electrolytic capacitors with a tantalum oxide layer acting as the dielectric medium, spaced by a layer of electrolyte. They offer advantages over conventional aluminum electrolytic capacitors such as low equivalent series resistance, higher capacitance density in a given case size, and improved temperature and frequency characteristics. The CWR29FC156KCFC Tantalum Capacitor is a popular option in the market and has several useful applications.

The CWR29FC156KCFC is a low-profile, stainless steel-encased, surface-mount, single-ended, non-solid electrolytic tantalum capacitor. It has an anode of tantalum and an electrolyte of an organic reflow solvent compatible with the vinyl-type surface-mountable body. The capacitor has an operating temperature range of -55 to 85 Celsius, a rating of 16 V DC, and an equivalent series resistance of 10 ohms at 1 kHz.

The CWR29FC156KCFC is designed for use in applications where there is a need for high capacitance values in a small, surface-mount case size. It has a capacitance range of 1.6 to 680 microfarads and a maximum ESR range of 5 to 20 ohms, depending on the capacitance. The capacitor is a popular choice for decoupling applications, where it helps stabilize a digital circuit by providing fast low-impedance current for high frequency transients. It can also be used for pulse applications, such as in telecommunications and automotive systems.

The working principle of the CWR29FC156KCFC is based on the electrochemical properties of tantalum metal. The metal’s ion sensitivity to the electrolyte makes it an ideal choice for capacitors. When a voltage is applied to the capacitor, the metal electrochemically transforms into the metal oxide (i.e., tantalum oxide) layer, creating a layer of insulation between the conductive plates. This insulation prevents electrical energy from passing through the dielectric, thus holding a charge and allowing the capacitor to act as a storage device. In addition, the capacitor components are lined with special materials to improve their performance and safeguard them from excessive voltages, temperature fluctuations, and electrical noise.

Overall, the CWR29FC156KCFC is an excellent option for applications requiring high capacitance values in a small case size. Its low ESR and high stability make it a reliable choice for numerous applications, including decoupling, power supply bypassing, buffering, and coupling. With its high-quality construction and low operating temperature range, the CWR29FC156KCFC is an ideal choice for designers and engineers who need a capacitor that meets their specific performance requirements.
