Tantalum capacitors are used in all types of consumer and industrial equipment, including medical electronics, radar systems, and communications systems. T491C227M004AT tantalum capacitors are no exception. These capacitors offer high quality that is reliable and dependable, making them perfect for critical applications.The T491C227M004AT capacitor is a Radial Lead tantalum capacitor with sealed finish. This device features a conductive polymer System-in-Package (SiP) construction, which reduces the leakage current and surge current requirements. The device is ideal for use in medical and research equipment, military and aerospace systems, and telecommunications networks. It is also suitable for use in computers, automotive systems, and consumer electronics applications.The T491C227M004AT capacitor has an operating temperature range of -55°C to +125°C. It comes with a capacitance value of 2.27µF / 25V DC. The temperature coefficient is ±15%, and the ESR rating is 8mΩ. It has a rated ripple current of 1A rms, and a maximum surge current of 30A rms. The device is also RoHS-compliant and Lead-free compatible, making it an environmentally-friendly component.The working principle of the T491C227M004AT capacitor is to store charge and energy for use by a circuit. Unlike other types of capacitors, the T491C227M004AT capacitor is made of an upper layer of a tantalum powder and a lower layer of a sintered electrolyte instead of a dielectric material like a ceramic for other types of capacitors. This unique construction allows it to store a significant amount of charge when compared to its size and operating temperature range.The T491C227M004AT capacitor has two electrodes, the anode and cathode. The anode is made up of a tantalum powder and serves as the positive electrode. It is attached to the metallic case, where it forms an electrical contact. The cathode is the negative electrode. It is connected to the sintered electrolyte in order to provide electrical contact.When a voltage is applied to the capacitor, the anode and cathode form an electrical field between them. This field allows for the storage of electrical charge, thus providing energy to the circuit. The capacitor does not lose its stored charge until the voltage is removed, allowing for the capacitor to retain its charge for longer than other types of capacitors.The T491C227M004AT capacitor is a reliable and dependable component that is perfect for critical applications such as medical and research equipment, military and aerospace systems, and telecommunications networks. Its operating temperature range, capacitance value, temperature coefficient, ESR rating, and Ripple current rating make it perfect for use in both consumer and industrial applications. Its conductive polymer construction further ensures high performance and a long lifetime.
