Fixed Inductors

Fixed inductors are electrical components that store energy when an electric current passes through it. They consist of a coil of wire, usually made of copper, wound into a circular ring. Inductors have the ability to regulate current flow when they are present in an electronic system.

The LAL03VBR33M is a fixed inductor designed to manage high frequencies. It is a non-polarized inductor with an inductance of 3.3µH. The LAL03VBR33M is constructed using two slotted ferrite rods for the core and two coils of insulated copper wire in series. The overall size of the LAL03VBR33M is 0.44 x 0.40 x 0.40 inches (11.2 x 10.3 x 10.3 mm). It has a saturation current of 210 mA, a DC resistance of 13 mΩ and an operating temperature range of -55°C to +85°C. The LAL03VBR33M is also RoHS compliant and halogen free.

The LAL03VBR33M is typical used in audio crossover designs and in circuit designs for EMI suppression. In audio applications, an inductor helps to shape the frequency response of a design by creating a low pass or high pass filter. It can also be used as an attenuator, which lowers the amplitude of a signal. In EMI suppression, the inductor can absorb electrical interference and prevent it from interfering with other components in a design.

The working principle of the LAL03VBR33M is based on the property of inductance. When a current flows through the inductor, the electrons in the wire build up and create a magnetic field. As the current changes, so does the magnetic field, and this creates a voltage (back EMF-electromotive force) within the inductor. This voltage is proportional to the current, so it acts to cancel out the current, thus reducing the amount of current that can flow through the coil.

The LAL03VBR33M is a reliable fixed inductor designed for high frequency applications. It provides superior EMI suppression and can be used for audio crossover designs. The device is RoHS compliant and halogen free, making it safe for use in most environments.
