LQH32MN271K23L

Fixed Inductors

Fixed inductors refer to a class of inductive components whose inductance values are fixed, and are usually used as part of a larger, more complex electronic circuit. These inductors are a key component in most power conversion circuits and can be used for a wide variety of applications, such as filter circuits, ground loop applications, and even EMI suppression. As the name suggests, these components are typically very small in size and consist of a Coil or a ferrite core.

LQH32MN271K23L application field and working principle

The LQH32MN271K23L is a Low Profile Surface Mount Fixed Inductor that is part of Murata’s power inductor family. This inductor is ideal for a wide variety of converter applications, such as high-frequency DC/DC converters, AC/DC converters, and DC/DC converters. Its ultra-low profile allows it to be mounted onto any PCB and allows for minimal interference with surrounding components. The LQH32MN271K23L has an inductance of 271uH, has a direct-current resistance (DCR) of 0.030Ω, and can handle up to 2.2A of current with a power rating of 5 W.

The coil in the LQH32MN271K23L is constructed using a high-performance flat winding technology, which has also been used in other Murata products such as shielded inductors, power inductors and chokes. This allows for an improved performance when suject to high frequency switching. The flat winding also enables improved resilience against impacts and vibration, which allows for excellent durability when the inductor is subject to environmental perturbations.

At the core of the LQH32MN271K23L is a ferrite core that is constructed using high-permeability ferrite material. This allows for excellent noise suppression, as it the core absorbs energy from the magnetic field created by the switching of the inductor. In addition, the ferrite material also helps to absorb vibration, which helps to increases the durability of the inductor.

The LQH32MN271K23L works by creating a magnetic field when it is current, which is then used to store energy. This is then released when the current is stopped, creating an opposing current to the original current. This effect helps to reduce the voltage spikes and improves power quality, making it an ideal choice for power circuits. The LQH32MN271K23L is also highly reliable, as it can handle a wide range of temperatures and voltages with minimal degradation.
