series introduction
# Introduction to the LQH5BPN150M Product Series
## 1. Overview
The LQH5BPN150M product series is a high - performance inductor series designed to meet the diverse needs of modern electronic circuits. Inductors are fundamental passive components in electronic systems, and the LQH5BPN150M series stands out with its unique features and excellent performance, making it suitable for a wide range of applications.
## 2. Key Specifications
### Inductance Value
The "150" in the model number LQH5BPN150M indicates an inductance value of 15 μH (microhenries). This inductance value is carefully calibrated to provide the appropriate magnetic field storage and energy transfer capabilities required in various circuits. It allows for precise control of current flow and impedance matching in different operating conditions.
### Tolerance
The "M" in the model number represents a tolerance of ±20%. This means that the actual inductance value of the inductor can vary within 20% of the nominal 15 μH value. While this may seem like a relatively wide tolerance, it is well - within the acceptable range for many general - purpose applications. For circuits where more precise inductance values are required, additional calibration or selection of components with tighter tolerances may be necessary.
### Size and Package
The LQH5BPN150M series is designed with a compact and standardized package. The specific dimensions are optimized to fit into modern printed circuit boards (PCBs) with limited space. The small form factor makes it suitable for use in miniaturized electronic devices such as smartphones, tablets, and wearable devices, where space is at a premium.
### Rated Current
These inductors have a specified rated current, which is the maximum continuous current that the inductor can handle without significant degradation of its performance. The rated current is determined by factors such as the wire gauge used in the inductor winding, the core material, and the overall design. For the LQH5BPN150M series, the rated current is carefully selected to ensure reliable operation in a variety of power - related applications.
### DC Resistance (DCR)
The DC resistance of the inductor is an important parameter as it affects the power loss in the circuit. A lower DCR means less power is dissipated as heat, resulting in higher efficiency. The LQH5BPN150M series is engineered to have a relatively low DC resistance, which helps to minimize power losses and improve the overall energy efficiency of the circuit.
## 3. Core Technology and Design
### Core Material
The inductor uses a high - quality core material that is carefully selected to provide excellent magnetic properties. The core material has a high magnetic permeability, which allows for efficient magnetic field generation and storage. This results in a more compact inductor design while maintaining high inductance values. Additionally, the core material has low core losses, which helps to reduce energy dissipation and improve the overall performance of the inductor.
### Winding Technology
The winding of the inductor is a critical process that affects its electrical and mechanical properties. The LQH5BPN150M series uses advanced winding techniques to ensure uniform winding distribution and tight coupling between the turns. This helps to minimize parasitic capacitance and improve the inductor's high - frequency performance. The winding is also designed to withstand mechanical stress and temperature variations, ensuring long - term reliability.
## 4. Applications
### Power Supply Circuits
In power supply circuits, the LQH5BPN150M series can be used as a filter inductor. It helps to smooth out the output voltage by storing and releasing energy in the magnetic field. This reduces the ripple voltage and improves the stability of the power supply.
