Fixed inductors are electronic components used in electronic circuits to store electrical energy or to generate ac power at fixed frequency. They are used to provide insulation against shock or to act as filters and limit AC voltage or currents. SDR0403-150ML is a type of fixed inductor with wide application fields and certain working principles.

SDR0403-150ML is a molded solid inductor with a diameter of 0.40 inches and a height of 0.31 inches. It has a 130mH inductance value at 1,000kHz with a maximum DC current rating of 368mA. Its resistance value is 79mohm. It has good performance in environmental factors including temperature, humidity, salt mist and shock.

SDR0403-150ML has various application fields, such as automotive audio, smartphone, PC and consumer electronic applications. It is widely used in power filters, amplifiers, radiofrequency and other circuits. The inductor is suitable for a wide range of winding topologies including bifilar, single-layer and multilayer bobbins. SDR0403-150ML is designed into a low profile inductor with high Q value that provide good performance in noise limitation and EMI (Electromagnetic Interference) suppression.

The working principle of SDR0403-150ML is based on Faraday’s law of induction. When an alternating current (AC) flows in an inductor, it produces an induced current in the opposite direction. This induced current causes a counter electromotive force (EMF) that opposes the change in current. This effect causes the inductor to act like a capacitor, which stores electrical energy over a specified time period. The stored energy can be released as an output current when the input currents change direction.

The SDR0403-150ML inductor also acts as a filter in DC to AC converter circuits. By connecting an inductor in series with a capacitor, the input signals are filtered and the output signals become more stable. This helps to reduce the surge current issues that arise when an inductor is used to filter out unwanted noise.

SDR0403-150ML is thus a versatile inductor with wide application fields and certain working principle. The inductor is designed for low profile, high Q value and good performance in temperature, humidity, salt mist and shock. It is used in DC to AC converters and power filters to filter out unwanted signals and reduce the output surges caused by the inductor. SDR0403-150ML is the preferred choice for manufactured electrical products and is widely used in automotive audio, smartphones, PCs and consumer electronic applications.
