# IHLP5050FDER2R2MA1 Product Series Introduction
## 1. Overview
The IHLP5050FDER2R2MA1 belongs to a high - performance inductor product series. Inductors are fundamental passive components in electronic circuits, and this particular series is designed to meet the demanding requirements of modern electronic applications. These inductors play a crucial role in energy storage, filtering, and impedance matching, making them essential for the proper functioning of a wide range of electronic devices.
## 2. Physical Characteristics
### 2.1 Dimensions
The IHLP5050FDER2R2MA1 series features a standardized 5050 package size. This size specification is carefully engineered to ensure compatibility with common printed circuit board (PCB) designs. The compact form factor allows for efficient use of board space, which is especially important in applications where miniaturization is a key requirement, such as in mobile devices and portable electronics.
### 2.2 Construction
These inductors are constructed using high - quality materials. The core material is selected for its excellent magnetic properties, which contribute to the inductor's performance. The winding is made of a suitable conductive material, typically copper, which offers low resistance and high conductivity. The combination of these materials results in an inductor that can handle high currents while maintaining low power losses.
## 3. Electrical Specifications
### 3.1 Inductance
The "2R2" in the product code indicates an inductance value of 2.2 μH (microhenries). Inductance is a measure of the inductor's ability to store energy in a magnetic field when current flows through it. This specific inductance value makes the IHLP5050FDER2R2MA1 suitable for a variety of applications, including power supply filtering and DC - DC converters.
### 3.2 DC Resistance (DCR)
The DC resistance of the inductor is an important parameter as it affects the power loss and efficiency of the circuit. The IHLP5050FDER2R2MA1 has a relatively low DCR, which means that less power is dissipated as heat when current passes through the inductor. This low DCR contributes to the overall energy efficiency of the electronic system in which the inductor is used.
### 3.3 Saturation Current
The saturation current is the maximum current that the inductor can handle before its inductance value starts to decrease significantly. The IHLP5050FDER2R2MA1 is designed to have a high saturation current rating. This makes it suitable for applications that require high - current handling capabilities, such as in power supplies for high - performance processors and graphics cards.
### 3.4 Self - Resonant Frequency (SRF)
The self - resonant frequency is the frequency at which the inductor's inductive reactance and capacitive reactance are equal. The IHLP5050FDER2R2MA1 has a well - defined SRF, which is important for applications where the inductor is used in high - frequency circuits. It ensures that the inductor performs optimally within its specified frequency range and helps to prevent unwanted resonances that could degrade the circuit's performance.
## 4. Performance Advantages
### 4.1 High Efficiency
Due to its low DCR and high saturation current, the IHLP5050FDER2R2MA1 offers high efficiency in power conversion applications. This means that less energy is wasted as heat, resulting in lower power consumption and longer battery life in portable devices.
### 4.2 Low EMI (Electromagnetic Interference)
The inductor's design helps to minimize electromagnetic interference. This is crucial in modern electronic systems, where multiple
