Fixed Inductors are a vital part of any electronic system. They are used to provide inductance in a circuit, which is required for many circuits for various purposes such as to reduce signal frequency, to provide a voltage regulation, to avoid power dissipation or to protect against electromagnetic interference. The SPM3015T-4R7M-CA Fixed Inductor from Sumida is one type of such inductors. The SPM3015T-4R7M-CA is a high-quality, high-inductance Fixed Inductor, specifically designed to minimize electromagnetic interference (EMI). It has a inductance value of 4.7 mH and is ideal for circuits with high frequencies. The inductor can operate in temperatures between -40deg to +125deg and has a rated current of 2.2A. The SPM3015T-4R7M-CA Fixed Inductor has a wide range of applications. It can be used in audio related applications, such as pre-amps, equalizers, crossovers and other audio signal routing and conditioning systems. It can also be used in automotive electronics as a filter for shock proofing, to reduce noise, and to improve signal integrity. It is also used as a filter inductor in power supplies, to filter out any undesired energy from the power supply circuit. The working principle of a Fixed Inductor is based on the theory of Faraday’s Law of Electromagnetic Induction. When a current is passed through the inductor, a magnetic field is generated which, in turn, induces an electromotive force (emf). This emf opposes any change in the current, thus counteracting any changes in the frequency of the signal. This helps in providing voltage regulation for the circuit and also inductance to reduce the frequency of the current.The SPM3015T-4R7M-CA is a great example of how Fixed Inductors can be used in various applications. It has been designed to minimize electromagnetic interference, which is a major concern often associated with high frequencies. Its wide range of applications, high-quality performance and compact size make it a great choice for audio related and automotive electronic systems.
