T491C157M006AT7280 Tantalum Capacitors
T491C157M006AT7280 is a type of capacitor that uses tantalum for its dielectric. These are relatively small surface-mount devices, similar to ceramic capacitors in size and characteristics. Tantalum capacitors are widely used in computers, telecommunications, automotive and portable electronic devices.
Tantalum capacitors are constructed with a layer of tantalum metal deposited onto a substrate, called an anode, forming the positive terminal of the capacitor. A porous layer, known as the dielectric, is then placed over the anode, followed by a layer of metal tantalum, or anode dust, which forms the negative terminal. The anode and anode dust are separated by an electrolyte either in the form of an aqueous liquid or a dry solid.
T491C157M006AT7280 tantalum capacitors are non-polarized devices with low equivalent series resistance (ESR). They have a high capacitance-to-volume ratio and can handle large amounts of current. They are also less prone to failure in extreme temperatures compared to other types of capacitors.
T491C157M006AT7280 tantalum capacitors are used to smooth out ripple in electronic power supplies and to reduce the effects of noisy AC signals, such as those that occur in digital circuits. They are also used to improve the performance of communication systems by providing better signal filtering.
T491C157M006AT7280 tantalum capacitors have many applications in the fields of electronics, automotive and military systems, and telecommunications. In the automotive industry, they are used to store energy, reduce noise interference and increase the performance of the vehicle\'s electrical system. In military systems, they are used to secure critical data against electromagnetic interference (EMI). In telecommunications systems, they are used to improve the signal-to-noise ratio of radio frequency (RF) and microwave signals.
T491C157M006AT7280 tantalum capacitors integrate two vital elements which contribute to the device\'s general performance. These elements are the dielectric material and the terminal type. The dielectric material used in the T491C157M006AT7280 is an alloy of a tantalum powder filled organic resin. This organic resin is capable of withstanding high temperatures up to +125 °C and is used as a covering over the anode and anode dust, which are separated by large electrolyte plates. The terminal type is a radial lead with quick-connect terminals and is designed to be compatible with any soldering processes used during the production cycle.
The T491C157M006AT7280 tantalum capacitor is a reliable, low-profile, and cost-effective solution for a broad range of industrial and consumer applications. Its tight tolerance and low ESR enable it to perform even in the most demanding environments. Additionally, its small form-factor enables its use in high-density systems, offering designers flexibility in PCB layout and design.
Due to its unique construction, T491C157M006AT7280 tantalum capacitors are ideal for use in space-constrained applications with high power requirements, such as telecom systems and computer motherboards. Its low leakage current, high dielectric strength, high temperature operating range, and excellent frequency response make it an ideal choice for applications such as signal filtering, decoupling, and bypassing. Additionally, its long shelf-life and low self-discharge characteristics make it an excellent choice for applications requiring long-term reliability.
