Tantalum - Polymer Capacitors
T540D337M004CH8505 is a tantalum – polymer capacitor that offers superior thermal stability and energy density relative to wet tantalum capacitors. It is a type of solid-state electrolytic capacitor that is most commonly used in military, aerospace, and medical applications. Its low ESR, excellent reliability and long shelf life make it an ideal choice for such applications.The main feature of the T540D337M004CH8505 capacitor is its extremely low ESR (Equivalent Series Resistance). The ESR is a measure of the amount of resistance that the capacitor presents to the flow of an alternating current, and is usually expressed in Ohms. This capacitor boasts extremely low ESR values of between 0.009 Ω and 0.032 Ω, making it particularly suitable for use in military and aerospace applications where low-ESR capacitors are required.However, the main drawback of the T540D337M004CH8505 is its limited capacitance range. The capacitance range is typically limited to 10 μF to 47 μF, which is relatively low when compared to other components, such as aluminum electrolytic or film capacitors. This makes it unsuitable for applications that require large capacitance.The working principle of the T540D337M004CH8505 is similar to that of wet tantalum capacitors. It consists of a tantalum powder-filled pouch, which acts as the dielectric material, and two layers of conductive polymer which act as the plates. The dielectric and conducting layers are separated by a layer of silicone dioxide, which prevents electrical shorts and increases dielectric strength.The construction of this capacitor makes it particularly suitable for high frequency and pulse applications. The low ESR is ideal for reducing ripple in DC-DC switchmode power supplies, thereby allowing for more efficient operation. The construction also allows for superior thermal stability compared to wet tantalum capacitors, making it ideal for applications that operate in harsh environmental conditions.Due to its superior reliability and thermal performance, the T540D337M004CH8505 is the preferred capacitor for use in military, aerospace and medical applications. This type of capacitor is also ideal for use in applications that require miniature size, such as handheld devices and computers. The long shelf life makes it an ideal choice for customers who are looking for components with long-term availability.The specific data is subject to PDF, and the above content is for reference
