Fixed Inductors

Inductors, also known as coils and chokes, are passive electronic components used to store energy in the form of a magnetic field. Fixed inductors, as the name suggests, are inductors with fixed inductance characteristics that cannot be adjusted. A fixed inductor might be constructed as a single core or as a part of a transformer package. The LDS0705-3R3M-R is one type of fixed inductor.The LDS0705-3R3M-R is a high-performance, small-size fixed inductor with tight ramp control characteristics. Its inductance value is 3.3 nanohenry, and its maximum allowable operating frequency is up to 5 MHz. It is housed in a compact, high-temperature resistant, plastic shell and is ideal for use in circuits that require high efficiency and require minimal space.The LDS0705-3R3M-R features low core losses, high Q characteristics, tight temperature coefficient, and large current carrying capacity. The low core losses make it particularly suitable for high-frequency applications such as radio frequency (RF) circuits. In addition to its very low distributed capacitance, another outstanding feature of the LDS0705-3R3M-R is its tight temperature coefficient. The tight temperature coefficient allows the LDS0705-3R3M-R to remain stable under different temperatures and prevents it from becoming thermally unstable.The working principle and operation of a fixed inductor such as the LDS0705-3R3M-R are relatively simple. When a voltage is applied to the terminals of the inductor, a current passes through it. The current produces a magnetic flux, and the magnetic flux produces a back electromotive force (EMF). This back EMF opposes the applied voltage, causing the current to decrease, and resulting in an inductive reactance. This inductive reactance reduces the applied voltage and keeps the current from increasing.The LDS0705-3R3M-R has many applications. The inductor is most suitable for DC-DC switching regulators, as its small size and high efficiency allow it to deliver good current regulation. It is also an excellent choice for power factor correction (PFC) circuits, NF and RF amplifiers, and other types of high-power switching applications. The fixed inductor is also suitable for applications requiring high heat dissipation, such as in voltage mode power supplies.In conclusion, the LDS0705-3R3M-R is a high-performance, small-size fixed inductor with tight ramp control characteristics. It features low core losses, high Q characteristics, tight temperature coefficient, and large current carrying capacity. It is most suitable for DC-DC switching regulators, PFC circuits, NF and RF amplifiers, and other types of high-power switching applications.
