Fixed inductors are commonly used in radio frequency, audio, power, and other electronic circuit elements. The 42282C is a type of fixed inductor, consisting of an internal winding, a core material, and a magnetic shield or core. This type of inductor can be used in a variety of applications, such as filtering, buffering, and AC line separation.

The 42282C is a surface mount inductor with a number of characteristics that make it suitable for a range of applications. The most significant features are its low internal library, low saturation levels, high Q-factor, wide range of operating temperature, and high temperature stability. This single-layer surface-mount fixed inductor can be used in high-frequency/integrated circuits, such as RF/video transmission, LNA, modem, mobile base station, satellite modules, and switching power supply systems. It is also a good choice for AC/DC power lines, DC/DC converters, DC/AC converters, and telecommunications cable line filters.

The 42282C has a winding with two internal coils. The coils are short-circuited at the inner end and connected to the primary feed-out conductor at the outer end. The primary feed-out conductor is connected to the connector, which is then attached to the circuit board. The coil is wound around a core, which is in the form of an etched powder core, providing the magnetic shielding necessary for the inductor to perform its purpose.

The 42282C has a winding range of 0.12 to 0.14 µH, which provides the electrical characteristics necessary for a variety of applications. The core has a saturated core and the winding has an inductance of 15 µH. It has a good frequency response, with a range of -3 dB to 70 dB at 100 kHz. Its saturation levels are very low, with an RMS current between 1 A to 2 A. It also has a low Q-factor of 3, which means that it can provide accurate filtering.

The working principle of the 42282C is simple but effective. The inductor is designed to generate a magnetic field when a current is passed through it. This magnetic field then induces a voltage in the external circuit, providing the necessary electrical signal. The inductance of the 42282C helps to filter out interference from other components in the circuit. As the applied current passes through the inductor, the inductance limits the current, which in turn limits the voltage generated in the external circuit.

Overall, the 42282C is an effective and efficient surface mount fixed inductor for use in a variety of applications. It has an excellent frequency response, low saturation levels, high Q-factor, wide range of operating temperature, and high temperature stability. It is suitable for applications such as filtering, buffering, and AC line separation. It also provides good protection for the circuit against voltage spikes and interference.
