Fixed Inductors are electrical components used in many circuits to store energy in a magnetic field or to control the flow of electrical current. The B1047AS-390M=P3 is a fixed inductor with a specific size and range of features. This article will explore the application field and working principle of this particular model.The B1047AS-390M=P3 is a small inductor that is typically used in circuits that require filtering, enhanced noise rejection, and low resistance. This type of inductor is often used in low-power applications such as those in communications, automotive, and some medical devices. It is also ideal for use in circuits with high-voltage and current ratings.The B1047AS-390M=P3 has a range of specifications, including power, current, and ripple. It has a low DC resistance of 0.26 ohm, and a high inductance of 390 µH. The power rating for this model is rated at 2 watts, with a ripple current rating of 2A. The peak current rating is 2.2A, and its low ESR (Equivalent Series Resistance) at 10kHz is 0.34 ohm. The working principle of the B1047AS-390M=P3 is based on the electromagnetism principle of Faraday′s laws of induction. This principle states that a changing magnetic field can induce a current to flow in an electrical device. When a current is passed through a wire, it creates a magnetic field in the conductor. When the current changes in magnitude, it induces a magnetic field that interacts with the other components of the circuit. In the case of the B1047AS-390M=P3, this magnetic field induces a current in the inductor, which is then supplied to the circuit.The B1047AS-390M=P3 is used to filter or stabilize a signal or power supply. It also serves to block out unwanted signals and to smooth out registered noise in a power supply. The inductor achieves this by providing a low impedance path for the high frequency components of the signal. This reduces the impact of the signal on the other components in the system.In conclusion, the B1047AS-390M=P3 is a fixed inductor used in a variety of applications. Its low resistance, high inductance, and high power rating make it an ideal choice for low-power circuits. Its operating principle is based on Faraday′s law of induction, and it can be used for filtering or noise reduction. Its small size allows it to be easy to integrate into complex circuits, and its durability ensures that it can be used for a long time.
