Fixed inductors, such as the 103-122HS, are electrical components used in a variety of applications. They are also known as chokes, since they help limit the flow of electrical current in a circuit. The 103-122HS is a non-isolated 110 µH shield choke, with a current rating of 4.2 A at 70°C. Furthermore, it can operate over a temperature range of -40°C to 125°C.

The basic construction of a fixed inductor includes a threaded core wound with insulated copper wire. This winding typically contains two hand-wrapped coils with an outer jacket to protect against dust and humidity. The core gives the inductor its shape, while the winding provides the inductor’s inductance, which is measured in units of Henry (H). The 103-122HS has an inductance value of 110µH.

Fixed inductors are used in a variety of applications, such as DC-DC Converters, On/Off Switching Converters, DC Output Filters, and AC Line Filters. In a DC-DC converter, the 103-122HS is used to pass certain currents, while blocking others. This allows the converter to step down or step up the input voltage to match the desired output.On/Off switching converters use fixed inductors to create a stable output voltage. The 103-122HS inductor acts as an inductive load, helping regulate the output voltage. Meanwhile, DC output filters use the 103-122HS to reduce the ripple (noise) of a DC signal. AC line filters also use the 103-122HS to reduce the noise from AC signals, such as the line voltage from the wall socket.

The working principle of fixed inductors is simple. When a voltage is applied to the 103-122HS, it generates an electromagnetic field. This field, in turn, opposes the flow of current, thus limiting the current and providing an impedance to the circuit. The larger the inductance value of the inductor, the greater the opposition to the current flow -- and hence, the higher the impedance.

The 103-122HS is a high-quality, shielded inductor that is suitable for use in many applications. Its wide operating temperature range and excellent current handling capacity make it a reliable and cost-effective choice for many applications. With its superior performance and high value, the 103-122HS is an ideal choice for your electrical needs.
