Fixed Inductors

An inductor, also known as a coil or a reactor, is a passive electrical component. It is a type of electrical component that is designed to store energy in a magnetic field when electric current passes through it. The most common type of inductor is a fixed inductor such as the PD54R-102M.The PD54R-102M is a fixed inductor that is typically used in switch-mode power supplies and other related circuits. Its main purpose is to smooth out the pulsing nature of switch-mode power supply circuits and to provide effective filtering of electromagnetic interference (EMI). The PD54R-102M is a cylindrical, non-magnetic, radial leaded device. It consists of a ceramic core wound with enameled copper wire and sealed in a plastic case. It has a voltage rating up to 25 volts and operating temperature range of -20C to 125C. It\'s rated for an inductance of 10.2uH at 10 mA of current.The working principle of the PD54R-102M is based on the fundamental law of electricity - Faraday’s Law of Electromagnetic Induction. According to this law, when electrical current flows through a wire, it creates a magnetic field. This magnetic field then induces a voltage in a coil of wire that is wrapped around the wire. This induced voltage causes a current to flow in the coil, which in turn produces a magnetic field of its own. The magnitude of the voltage induced is directly proportional to the rate of change of the magnetic field. This effect is known as electromagnetic induction.In the case of the PD54R-102M, the current that flows through the ceramic core creates a magnetic field. This magnetic field then induces a voltage in the coil of wire wrapped around the core. The induced voltage causes a current to flow in the coil, which in turn produces a magnetic field. The combination of the magnetic fields creates an inductance in the device, which is measured in Henries (H). The higher the value of the inductance, the stronger the magnetic field and higher the ability of the device to store energy.The PD54R-102M is an ideal device for application in switch-mode power supplies, LED drivers, DC-DC converters and signal conditioning circuits. Its main attributes include EMI filtering, low DC resistance, low tolerance, and a wide operating temperature range. In conclusion, the PD54R-102M is a fixed inductor that is used in various applications such as switch-mode power supplies, LED drivers, DC-DC converters and signal conditioning circuits. It is based on the Faraday’s law of electromagnetic induction and produces an inductance based on the current flowing through the ceramic core. Its main attributes include EMI filtering, low DC resistance, low tolerance, and a wide operating temperature range.
