Fixed Inductors are electrical components with a specific inductance value, meaning they generate a specific amount of counter EMF when they encounter an ingredient of changing current. DR73-470-R is a fixed inductor with a rated inductance of 470mH, and is widely used for a variety of applications.In circuit design, the DR73-470-R is commonly used in switching power supplies, dc-dc converters, inductive switching applications, and is also a common choice for constructing LC filters.For switching power supplies, fixed inductors such as the DR73-470-R are used as filters to reduce EMI noise, and the coils used must be able to handle high ripple current, high frequencies, and pulse width modulation. The 470mH inductance gives the DR73-470-R strong high frequency characteristics and excellent EMI suppression.In inductive switching applications, the DR73-470-R is often used as an energy storage device, such as a flyback transformer. The 470mH value is often chosen because it provides enough energy to efficiently charge and discharge in the switch, and the current and voltage may vary considerably, with the 470mH inductance providing just enough buffer to reduce the risk of overloading the switch.LC filters are also a common application for the DR73-470-R. As the name suggests, an LC filter is made up of both capacitors and inductors. The DR73-470-R serves as the inductor, and together with capacitors it forms a parallel or series LC filter. In parallel LC filters, the inductor eliminates low frequency noise, and the capacitors eliminate high frequency noise. Similarly, in series LC filters, the inductor eliminates high frequency noise and the capacitor eliminates low frequency noise. The DR73-470-R\'s 470mH inductance is judged to be an appropriate value for many LC filters, providing good length compensation of the filter performance, so that it can keep both high and low frequency noise under control.Aside from these, the DR73-470-R is also used in other applications such as antenna matching, antenna impedance transformation, and RF matching, thanks to its ability to provide high impedance at resonance.The DR73-470-R is a wideband inductor made of soft ferrite and has a working frequency range of 20KHz-50MHz. It has a very low DC resistance of less than 0.08Ω, which helps the overall current resistance to be low. The DR73-470-R also has a low loss characteristic, making it suitable for use in high-efficiency applications.The working principle of a DR73-470-R is that, when exposed to a changing current, it creates a counter EMF proportional to the rate of change of current. The DR73-470-R\'s 470mH rating means that it will generate an EMF of 470mV when exposed to a current with a rate of change of 1A/s. This counter EMF can be used to increase or decrease the current flowing through a circuit, depending on the application. Overall, the DR73-470-R is an excellent and widely-used inductor across many applications including switching power supplies, inductive switching, and filters. With its 470mH inductance and high frequency characteristics, it provides excellent performance and flexibility for its users.
