Fixed InductorsFixed inductors, also known as chokes, are components that offer electrical resistance to alternating currents, providing inductive reactance. More precisely, they offer low resistance to AC current, which causes a frequency-dependent impedance with the capacitance in the circuit. This makes them a crucial part of many control applications, since they can partially or totally block the AC signal while allowing the flow of DC current. This article will discuss the application field and the working principle of the PE-53803 fixed inductor.The PE-53803 is a SMT Common Mode Fixed Inductor, offering high efficiency performance and high power level in a compact, cost-effective package. Its properties include an operating temperature of -55°C to +125°C, a 50mA DC Current Rating, a 0.35Ω RDC max and an Inductance of 10.0nH ±10%. It is designed for automotive, consumer and datacom applications, and is suitable for use in 12V-24V supply systems.In terms of application, the PE-53803 is frequently used in automotive electronics for anti-noise, filtering, DC-DC converter, LTE/LTE-A antenna duplexer matching, and telecommunications, among other applications. Its common mode capability makes it particularly suitable for these uses, where it can guard against crosstalk and impedance mismatches. The PE-53803 is also suitable for applications that require higher current rating, given its lower DCR rating in comparison to other models.The working principle of the PE-53803 lies in its inductive reactance. When an AC current is applied, the inductor offers low resistance and high reactance, due to its coil of wire. This reactance causes a frequency-dependent impedance with the capacitance in the circuit, which partially or totally blocks the AC signal while allowing the passage of DC current. As a result, the common mode feature of the PE-53803 is used in power supplies, motor controls, and telecommunications, helping reduce crosstalk and impedance mismatches.Lastly, it is important to note that the PE-53803 offers high efficiency performance. Its highly conductive copper coil ensures minimal power losses, even when running with high frequencies. Furthermore, its outer shield helps shield it from external interference and noise, further improving efficiency.In conclusion, the PE-53803 is a fixed inductor that offers many benefits and capabilities in a range of applications. Its low resistance to AC current, high power level, and common mode features allow it to be used in automotive electronics, consumer devices, datacom networks, and other areas. Furthermore, its inductive reactance cause a frequency-dependent impedance with the capacitance in the circuit, while the outer shield helps protect the inductor and retains high efficiency performance.
