Fixed inductors are passive components that store electrical energy in its magnetic field when energy is applied to it. The inductor is composed of two parts, the inductor core and the coil, which are basically wires wound around a core of magnetic material, such as iron or ferrite. When current is applied to the inductor, a magnetic field is created around the induction core, which in turn induce a voltage proportional to the change in current, known as self-inductance. This property of inductor or inductance is measured in Henrys (H) and is particularly useful in circuits that require an electrical current to be regulated or changed, either in time or in amplitude.

SD3814-101-R is one such fixed inductor, commonly used in filter circuits, tuning circuits, and signal conditioning applications. It is made up of a rectangular block of ferrite core material, with several turns of wire wound around it. The overall size of the inductor is 38mm x 14mm, with a height of 1.0mm, a rated impedance of 10 mΩ, and a capacitance of 101 +/- 15%. This particular inductor has an operating temperature range of -55°C to +125°C.

The working principle of the SD3814-101-R is quite simple. When an alternating current is applied to the inductor’s terminals, the electromagnetic field created by the current causes the magnetic core material to become magnetized. The magnetic field generated by the core in turn induces a voltage in the coil, which is proportional to the amount of current flowing through the inductor. This induced voltage works to oppose the current, thus reducing the current’s rate of change, and thereby producing a self-regulation or “filtering” effect on the current.

The SD3814-101-R is generally used in applications such as amplifier circuits and sensing systems, where it can effectively filter out unwanted electrical noise and provide regulation of the AC signal. The device is also useful in frequency control and bandpass filtering, as it can offer wide frequency response, high quality factor, and low loss. The inductor is also highly durable and reliable, having an expected life of up to 5000 hours under normal operating conditions.

Fixed inductors such as the SD3814-101-R are essential components in many electronics, providing essential voltage and current regulation and noise filtering. As such, they are a necessary component in a variety of electronics such as audio amplifiers, tuned circuits, radio receivers and transmitters, and various other signal conditioning and control circuits.
