Fixed Inductors are components with a special function within the electrical circuit, such as energy storage, smoothing and signal signal processing. As their name suggests, fixed inductors are not usually adjustable after they have been installed. The ELJ-NDR12JF, manufactured by Renesas Electronics, is one such fixed inductor.
The ELJ-NDR12JF is a fixed inductor that can handle up to 3A of current in a power range from 4-45V. It is a low profile, surface mount device with a height of just 1.2 mm above the board and with a maximum outer diameter of just ⌀ 12 mm. Additionally, the ELJ-NDR12JF exhibits excellent inductance sensititivty with a maximum of +25%/-20% tolerance.
Due to its small size, the ELJ-NDR12JF is ideally suited for use on portable electronic products such as smartphones, tablets and wearables. It is also suitable for use in automotive or industrial control applications due to its wide temperature range (-40°C to +125°C).
ELJ-NDR12JF Working Principle
The ELJ-NDR12JF operates on an electrical principle known as a electromagnetic induction. This principle states that a voltage is induced in a wire when it passes through a varying magnetic field. In the case of the ELJ-NDR12JF fixed inductor, an electromagnetic coil is wound around a core material in order to produce the varying magnetic field.
When a current is applied to the ELJ-NDR12JF, it creates a varying magnetic field which then induces a opposing voltage across the coil. This voltage is then “transferred” back into the original power source via the capacitor, and in turn, adds inductance into the circuit. This inductance then works to regulate the flow of power in the system and to reduce any unwanted high frequency noise.
Conclusion
The ELJ-NDR12JF fixed inductor, manufactured by Renesas Electronics, is a small, low profile surface mount device designed for high current applications such as those found in portable electronics, automotive and industrial control environments. Coils wound around a core material produce a varying magnetic field which induces a opposing voltage back into the original power source. This inductance then works to regulate the flow of power in the system.
