Fixed Inductors

A fixed inductor or inductive coil (also called a choke) is an electronic component made up of one or more inductively coupled windings. These inductive coils are used in many electronic circuits, such as filters, resonant circuits, power supplies and oscillators. They are most commonly used in power circuits, as they help stabilize the voltage and reduce power losses. In larger inductors the windings are wound with a high grade and resisting insulation to reduce the winding losses.

LQH3NPN3R3NJ0L Application Field and Working Principle

The LQH3NPN3R3NJ0L fixed inductor is a SMT 0805 package DC inductor, typically used in power electronic circuits and applications such as switch mode power supplies (SMPS), motor controllers, high frequency switching circuits and audio circuits. The LQH3NPN3R3NJ0L has a high inductance (0.3uH) and a high saturation current (3.3A). It is also fast acting and has a low DC resistance (0.06Ω), making it suitable for high frequency circuitry where the current is highly transient.

The working principle of a fixed inductor is based on Faraday\'s Law of Electromagnetic Induction. When a current is applied to the inductor, a magnetic field is generated around the windings. This magnetic field stores energy in the form of a magnetic field and causes the current in the inductor to be limited. This current limiting effect is what makes the fixed inductor so effective in regulating the voltage of the circuit. It also helps reduce power losses due to voltage transients, thereby increasing circuit efficiency.

The LQH3NPN3R3NJ0L has a rated operating temperature range of -40℃ to +85℃ and is AEC-Q200 approved. It also features ESR construction for superior thermal performance, as well as high thermal, thermal shock and mechanical shock resistance. This product has also passed UL 94V-0 certification which makes it a perfect choice for a variety of applications.

The LQH3NPN3R3NJ0L is ideal for applications such as communications, medical electronics, power control, industrial electronics, home automation, automotive, military and aerospace. It can be used in both linear and switching power supplies and is designed to handle high currents while providing excellent power factor stability. Moreover, the LQH3NPN3R3NJ0L is RoHS compliant and can be used in high temperature environments.

In conclusion, the LQH3NPN3R3NJ0L fixed inductor is a highly efficient and reliable inductor for use in a variety of power applications. With its high inductance, high saturation current and fast acting design, it is well suited for use in high frequency switching circuits and other power-based applications where the current is transient. Furthermore, its rated operating temperature range makes it suitable for use in high temperature environments while its AEC-Q200 and UL94V-0 certifications make it a perfect choice for most power applications.
