SRR3818A-470M Inductors, Coils, Chokes

Fixed Inductors

Inductors are components which store electrical energy in a magnetic field. A fixed inductor is a type of inductor which does not change inductance as current through it varies. The most commonly used fixed inductors are referred to as Chokes, due to the fact that they are often used to filter out high-frequency noise and spikes in a circuit. Their field of application is various, however a notable application would be in power supplies, where the smooth DC output voltage is important for performance.

The SRR3818A-470M is a type of fixed inductor, manufactured in an epoxy-coated metal case with laser-welded connection terminals. It features a shielded construction and a low resistance of 0.70 ohms. Its size and low DC resistance make it ideal for use in smaller systems, such as smartphones and other personal electronics. Additionally, its usable operating temperature range is between -55°C and +125°C.

The working principle of the SRR3818A-470M can be defined by its inductive property, in which current will generate a magnetic field around the coil of the inductor. As the magnetic field increases, the more the inductor will resist change in current, allowing it to be used as a choke in power supplies. Additionally, the SRR3818A-470M features a magnetically shielded design, which further reduces any stray electromagnetic fields from interfering with other components nearby.

In terms of application, SRR3818A-470M are widely used in power supplies where high-frequency noise and spikes need to be filtered out. Its high efficient operation makes it suitable for use in applications with stringent power supply performance requirements, such as in mobile phones, electric vehicles and other industrial equipment. In addition, this type of inductor is particularly useful when used with switching power supplies, as it is more efficient and can tolerate higher temperatures.

The SRR3818A-470M also offers high heat dissipation due to its metal case construction. The metal case absorbs the heat energy generated by the component and dissipates it into the surrounding air. This makes it useful for higher temperature applications where heat dissipation is a priority. Finally, the SRR3818A-470M has a long shelf life due to its epoxy-coated metal case, which can withstand high amounts of wear and tear.

Overall, it is clear to see why SRR3818A-470M are widely used in various applications. Their high operating efficiency, robust construction and high heat dissipation make them an ideal choice for any power supply system. This type of fixed inductor is reliable and offers excellent value for money, making it the perfect choice for engineers and designers alike.
