Fixed Inductors

A fixed inductor, such as the 4232-122F, is a passive electrical component consisting of a coil of insulated wire wound around a core material. This device typically has a low resistance, high inductance, and low power loss. The main function of an inductor is to store and release electrical energy in the form of a magnetic field.

Application Field

Fixed inductors are widely used in electronic circuits. They are used in radio transmitters and receivers, audio amplifiers, automotive sound systems, and other electronics that require transforming electric current into electromagnetic radiation. Inductors are also used in power supplies, oscillators, and modulation circuits for sound systems and television receivers. Furthermore, they can be employed in filters for AC current, motor control and static relays.

Working Principle

An inductor works based on the principle of electromagnetic induction, according to which, a changing magnetic field induces a current in a nearby conductor. Hence, when a voltage is applied to an inductor, a closed loop of flux is set up, and the induced current flows through the inductor’s coil. The voltage across the inductor’s terminals produces a force which opposes the change in the current, resulting in a ‘back EMF.’ Since an inductor’s current is proportional to its voltage, this back EMF increases exponentially with the rate of change of the current.

The 4232-122F is a high-quality, rectangular, compact radial inductor that features self-leaded terminals for an easy solder mount. It has a great power dissipation capacity of up to 40W, with a maximum mounting height of 43.5mm. The 4232-122F has a ferrite core and air cooling. Its operating temperature range is between -40°C to +105°C, and its storage temperature range is between -40°C to +105°C.
