Fixed inductors, also called lumped inductors, are two-terminal or multi-terminal devices intended for use at high frequencies with low loss. They are used to store energy in the form of an electrical field. They have a wide range of applications in radio-frequency electronics, including the adjustment of oscillator circuits, the coupling of radio frequency signals, tuning of amplifiers and receivers, decoupling of electronic systems, and the suppression of high frequency noise.

The 105-221HS is a high performance, low loss, high stability fixed inductor. This type of inductor is designed for use in the fast switching applications common in RF circuits such as power amplifiers, VCOs, power supplies, and digital communication systems. It can withstand an operating temperature range of -40 to +105°C, with a self-resonance frequency that gives exceptional high frequency performance. The 105-221HS is rated for a maximum DC current rating of 200mA and a maximum voltage rating of 20V.

The 105-221HS inductor is a small, surface mountable package with an integrated shield that helps minimize stray inductance. The shield also prevents EMI and helps reduce radiated and conducted noise caused by the inductor. The maximum inductance is 10uH, with a tolerance of ±20%. The maximum AC resistance is 7.5Ω, with a tolerance of ±15%, which helps maximize performance when used in fast switching applications.

The working principle of the 105-221HS is based on Faraday\'s law. This law states that when an electrical current is running through a wire an electromagnetic field is generated. This field induces an electromotive force in the inductor, which stores energy. The amount of energy stored is proportional to the inductance, the number of turns in the wire, and the current running through the inductor. When the current stops or changes the inductor releases the stored energy back into the circuit.

For applications that require a wide range of inductance, the 105-221HS can be combined with other components such as capacitors and resistors to form an LC circuit (a resonant circuit), which increases the adjustable inductance range. This type of circuit can be used to filter out high frequency noise, adjust oscillator circuits, and suppress EMI.

Overall, the 105-221HS fixed inductor is a high precision, low loss, and high stability component that is suitable for a variety of applications in the RF field. Its shield helps minimize noise emissions, while its wide temperature range and adjustable inductance capabilities make it a versatile choice for design engineers.
