Tantalum - Polymer CapacitorsTantalum - Polymer Capacitors, also known as Tantalum-Poly or Ta-poly capacitors, are a special type of electrolytic capacitors. The type of capacitors is made with a porous tantalum anode and an electrolytic polymer or gel-like dielectric material. The combination of the two materials creates a high-performance, low-cost and durable capacitor. The Ta-poly capacitors are used in many commercial products, such as cell phones, MP3 players, digital cameras, medical and automotive electronics as well as power supplies and audio amplifiers, due to their compact size, light weight and high reliability.The T540B107K004DH87107610 is a Ta-poly capacitor that has a rated capacitance of 47 μF, a voltage rating of 10V and is rated for temperatures between -55°C and 85°C. The general purpose Ta-poly capacitor has low equivalent series resistance (ESR) and has a long-term stability, making it suitable for applications such as energy storage and power conversion in automotive, telecom and computer applications. The capacitor is also able to withstand ripple currents and high temperature operating conditions without compromising its performance. The working principle of the Ta-poly capacitors is based on electrochemical double layer capacitance. The outer layer of the capacitor dielectric consists of an electrolyte, which is an electrically-conductive substance. This layer is sandwiched between two layers of porous tantalum anode and cathode material. When a voltage is applied across the capacitors, ions from the electrolyte move and deposit themselves along the anode and cathode surfaces, forming a double layer of charge. This double layer of charge is responsible for the capacitance of the device. The Ta-poly capacitors are generally used in filtering applications, timing and memory backup, power conditioning and other power management applications. They also provide high vibration, thermal and corrosion resistance, allowing them to be used under severe environmental conditions. The absence of polarity also reduces the possibility of accidental reverse voltage input, which may damage other components of the circuit. Furthermore, the low ESR and high reliability of these capacitors make them well suited for high current applications and for controlling current ripple. The main application field for the T540B107K004DH87107610 Ta-poly capacitor includes DC-DC power conversion, battery backup, noise reduction and surge protection, and high current loads. The capacitor is also used to reduce EMI in automotive, telecom and computer applications as well as in high temperature and ripple current applications. The capacitor is also used in cell phones, MP3 players, digital cameras and medical devices. In conclusion, the T540B107K004DH87107610 Ta-poly capacitor is a reliable, low cost and high performance type of capacitor that is suitable for use in many applications. The combination of the two materials, tantalum anode and electrolytic polymer dielectric, enables the device to withstand high temperature and ripple current without compromising performance. Furthermore, the capacitor is also useful in DC-DC power conversion, battery backup, noise reduction and surge protection, and high current loads.
