Tantalum - Polymer CapacitorsTantalum polymer capacitors, referred to as T540D337M003AH8605, are a type of capacitor constructed from a porous anode made from tantalum, with a surface layer of titanium dioxide. These capacitors provide superior performance for applications requiring high ripple current, low ESR (equivalent series resistance), high capacitance density and high power density.Tantalum capacitors are mostly used in systems requiring high capacitance and low voltage ratings, such as digital home theater systems, cellular phones, digital imaging products, and computers. Other uses include low-noise power supplies, vehicle electronics, medical instrumentation, hand-held electronic devices, and automotive systems. Typical applications include digital audio processing, analog and digital signal processing, power conditioning, medical instrumentation, and automotive electronic control.The T540D337M003AH8605 capacitors have a working voltage of 6.3 volts and are common in high performance applications where a large amount of space is needed with minimal heat generated. They have an operating temperature range of -55 to +125 degree Celsius and can store a maximum of up to 200volts. These capacitors also feature a low Equivalent Series Resistance (ESR), high current ripple ability, and long cycle life. The robust construction of these capacitors also allows for a wide range of environmental and temperature variability.The primary function of the T540D337M003AH8605 capacitors is to provide an efficient storage of electrical energy and a parallel electrical path to reduce high frequency noise. As with all capacitors, the capacitor’s construction, size, shape, and orientation within a circuit will affect the performance of the device. As capacitors get smaller, their ESR will also decrease, giving rise to higher ripple currents and less heat generated because of the faster discharge of electrical energy.The T540D337M003AH8605 capacitors are constructed with a tantalum powder core, which is covered in titanium dioxide and impregnated with a conducting polymer. This provides the capacitors with excellent high current and low ESR characteristics. The tantalum powder core is built up in layers, each layer having a width of 0.05mm, which is then sputtered with a layer of pure titanium dioxide. This acts to form a barrier between the core and the conducting polymer, as well as providing added structural integrity.The conducting polymer gives the capacitor its functionality and high current-carrying capability. It is also responsible for the high capacitance density and low ESR characteristics. The polymer is made up of polymerized radicals and monomers, which are then applied as an electrolyte between the layers of directionally-aligned, interlocked ceramic dielectric layers. This makes the capacitors able to store, discharge, and redistribute electrical energy quickly and efficiently.In addition to the electrolyte, the conductive polymer also acts to reduce the effects of corrosion. The polymer’s ability to seal out moisture and salts makes the capacitor highly resistant to corrosion. This extends the life of the capacitor and makes it suitable for environments where moisture and salts could be an issue.Finally, the T540D337M003AH8605 capacitors also feature a very low Equivalent Series Resistance (ESR). This translates to a longer service life, higher power density and lower energy losses. The low ESR also allows the device to handle high ripple current without the use of large inductors or additional filtering.Tantalum - Polymer Capacitors, particularly the T540D337M003AH8605, provide a reliable, efficient, and long lasting storage of electrical energy and is suited to many different applications. The capacitors are known for their impressive performance with high ripple current, low ESR, high capacitance density, and high power density. They are also highly resistant to corrosion, making them suitable for most types of environment. With such impressive characteristics, these capacitors are set to become the primary choice for electrical and electronic applications around the world.
