Fixed inductors are components that are used to store or filter electronic signals in areas such as power supplies, RF filtering, audio, and servo applications. They are typically made up of a coil of wire wound around either an electromagnetic core, an iron core (or both depending on the application) that is wound with insulated copper wire. Fixed inductors are usually found in the general categories of chokes or coils.

The SDR0503-181KL fixed inductor is a high-performance component designed for use in high-speed switching power supply/DC-DC converter applications. It features a low DCR, high-temperature stability and a very high-energy storage capacity. The SDR0503-181KL is encased in a UL94V-0 compliant package and has an operating temperature range of -55°C to +125°C. The SDR0503-181KL is a 2-pin inductor that is Asymmetrically shielded, RoHS compliant and meets UL and CSA safety standards.

The SDR0503-181KL inductor is designed to filter high-frequency noise in power converters to reduce EMI and improve the signal quality in high-speed switching applications. The inductor stores energy, generated by an input signal, and can sustain the energy even when the input signal is removed. This enables it to filter high-frequency noise that would otherwise be sent to the next stage of the circuit.

The working principle of the SDR0503-181KL works on the principle of inductive reactance. Inductive reactance means that an inductor resists a change in the current. When an AC current runs through an inductor, the growing and decreasing electrons create a magnetic field which opposes the change in the surrounding electrons. This opposition is known as inductive reactance. This reactance limits the amount of current that can pass through the inductor and helps to filter out any high-frequency noise.

The SDR0503-181KL is suitable for applications where noise filtering is required, such as DC-to-DC power conversion and high-speed switching applications. It is an ideal solution for DC-DC applications as it helps to reduce input capacitance, power dissipation, and reduces switching noise. The inductor also improves the efficiency of the circuit by limiting the current rise and fall times of the power supply.

The SDR0503-181KL fixed inductor can be used in various applications including audio, RF, and data processing applications. Audio applications include amplifiers and sound system designs that require signal conditioning to reduce noise and maximize audio performance. The inductor can also be used to filter out high-frequency noise in RF applications such as antenna design and wireless communication systems. It is also used in data processing applications to filter noise from signal lines or to protect sensitive components from voltage spikes.
