Fixed inductors are electrical components used to store electric energy in the form of an electromagnetic field. They are also known as chokes, coils, or inductors. The component’s basic principle is to create a closed loop circuit that allows current to build up in the inductor, storing energy in the form of a magnetic field. The 38H202C is a type of fixed inductor commonly found in electronic goods. It has several applications and works through the principles of inductance.

The 38H202C is a 2-pin vertically mounted, cylindrical inductor. Its construction is made of a core, a thin, flexible winding of copper wire, and an outer shell. Its inductance values vary from 1 to 1000 μH with a tolerance of +/– 10%. Its rated current is 282 mA and its rated voltage is 2.5 V to 25 V. The 38H202C can be used at temperatures ranging from +90°C to -55°C.

The 38H202C is applicable for use in a variety of fields related to electronic devices. In telecommunications, the 38H202C is often used in the design of antenna impedance matching circuits controlling input impedance levels of both radio transmitters and receivers. In the automotive industry, the 38H202C is frequently used in powertrain electronic control units. Uninterruptible power systems also incorporate the 38H202C in the unit’s AC to DC converter. Furthermore, these fixed inductors can be used in power supplies and as filters for switching circuits.

The 38H202C is constructed to create an electric current that increases and decreases constantly for specific time intervals. When an alternating current is passed through the winding of the fixed inductor, energy in the form of a magnetic field is inducted. This magnetic field, in turn, reacts against the supply current thus creating a counter-electromotive force. This system is commonly referred to as an oscillating circuit and it works according to Faraday’s Law. The counter-electromotive force reflects the changes in the current, while the inductor’s flux remains constant.

Therefore, the 38H202C is a type of fixed inductor often used in electronic devices. It finds application in a range of different markets including automotive, power and telecommunications. Its working principle is based on Faraday’s Law, in which a counter-electromotive force is created in order to regulate the supply current, while the flux of the inductor remains constant.
