Fixed Inductors
Fixed inductors, also known as inductors, are passive electronic components that store energy in the form of an electromagnetic field. When an electric current flows through the inductor, a voltage is induced across its terminals, which varies with the rate of change of the current. Fixed inductors play a significant role in many electronic applications, such as filters, charging circuits, and power conversion circuits. One example of a fixed inductor is the PD43R-102M.
PD43R-102M
The PD43R-102M is an axial ceramic core chip inductor. It is designed to be used in single-layer board applications for both power electronics and signal processing applications. The PD43R-102M has a rated current of 1 A, a maximum operating frequency of 10 MHz, and an inductance of 0.8 mH. It is UL-approved and RoHS compliant. In addition, the PD43R-102M has a low temperature coefficient, which ensures that the inductance remains stable over a wide range of temperatures.Application Field
The PD43R-102M can be used in a variety of applications requiring stable inductance. Common uses include power supply filters, switching power supplies, cellular communication amplifiers, low-noise amplifiers, and high-voltage power supplies. The PD43R-102M is also commonly used in the automotive industry, as well as in consumer electronics such as laptop computers and digital cameras.Working Principle
The working principle of the PD43R-102M is based on Faraday’s Law of induction. When an electric current flows through the PD43R-102M, a magnetic field is produced. When this magnetic field varies, an induced voltage is generated across the inductor’s terminals. This voltage, known as the back EMF, opposes the change in the current, resulting in a stable inductance for the circuit. This ensures that the current remains stable, even when the load on the circuit changes.
The PD43R-102M is an excellent choice for a wide variety of applications. Its high current rating, low temperature coefficient, and UL and RoHS approval make it an ideal choice for many different circuits. Its ease of use and wide range of applications make it a popular choice for engineers needing a reliable, stable inductor.
