Inductors are a type of passive component used in a variety of electronic circuits. Among inductors, fixed inductors are mainly used in the applications of RF circuits. The UP3B-220-R is a type of fixed inductor and the following are its application field and working principle.The UP3B-220-R fixed inductor works best in RF applications because of its higher self-resonance frequency, better Q (quality factor) characteristics, and lower loss tangent. It is suitable for power supplies, voltage regulators, communication lines, audio, broadcast, TVs, telephones, and computer engineering. Moreover, it is also widely used in all kinds of electronic power device designs.The inductance range of UP3B-220-R fixed inductor is between 0.22uH to 470uH and it works excellent at DC to 8.0GHz frequencies, up to 12.4GHz in some cases. Moreover, its maximum DC resistance is between 0.87 to 4.7 Ohms.The electric current flows through the inductor wire and creates a magnetic field. This magnetic field, in turn, forms a loop around the wire. According to Faraday’s law of induction, when a conductor is located in the alternating magnetic field, a voltage is induced in the conductor. This induced voltage opposes the applied voltage due to the polarity of the electromagnetic field.The UP3B-220-R fixed inductor features a high self-resonance frequency and a large Q (quality factor) value. It works by reducing the current change of the input current frequency and converting an alternating current to direct current. The working principle of the UP3B-220-R fixed inductor is that the electromagnetic field is generated and current is conducted in coils at the same time.It is worth noting that during operation, heat is generated from the UP3B-220-R fixed inductor due to the electrical resistance caused by the winding of the wire and dissipated into the surrounding environment. Therefore, it is necessary to consider the thermal resistance of UP3B-220-R fixed inductor in the design process.The UP3B-220-R fixed inductor is an important type of component used in electronic circuit designs. It is capable of operating in frequencies ranging from DC to 8.0GHz and has a wide range of applications in power supplies, voltage regulators, communication lines, audio, broadcast, TVs, telephones and computer engineering. Moreover, it also features a high self-resonance frequency, a larger Q (quality factor) value and lower loss tangent. The working principle of the UP3B-220-R fixed inductor is that the electromagnetic field is generated and current is conducted in coils at the same time. Heat is generated during operation and it is important to consider thermal resistance in the design process.
