Customized Chip Inductor with Wire Wound 33uH 330uH 22uH 220uH​ For Power Supply

1.Product Description

NR inductors are SMD power inductors, which are magnetic glue inductors. Because they are made by fully automated machines, they are also called automated shielding inductors. They feature a small and thin magnetic shielding structure. There are several families of NR power inductors: NR, NRH, NRS and NRV. These inductors are available in a variety of heights and sizes

The NR series offers the highest DC resistance option among NR inductors with a 4.8 Ω available.

2.Features:

1. High power processing capability
--Wire diameter and winding design: NR inductors generally use thicker enameled wire winding, and the number of winding turns is carefully designed to carry larger currents. The thicker wire diameter reduces wire resistance and minimizes heat loss when current passes through, making it suitable for circuits with high power requirements, such as the CPU power supply circuit of a computer motherboard, which can provide stable high current for the CPU.

--Good heat dissipation performance: In order to adapt to the heat generated by high-power operation, NR inductors pay attention to heat dissipation in their structural design. Some NR inductors use low magnetic resistance magnetic materials and open magnetic circuit design, which not only helps improve the performance of the inductor, but also makes it easier for heat to dissipate, ensuring the stability of the inductor's performance under high-power operation.

2. High inductance value
--Advantages of magnetic core materials: High permeability ferrite magnetic core materials are usually selected, which can effectively gather and enhance magnetic fields, enabling inductors to achieve high inductance values in limited space. High inductance value is crucial in circuit applications such as filtering and energy storage. For example, in the output filtering circuit of a switching power supply, a higher inductance value can make the output current smoother and reduce voltage fluctuations.

3. Low DC resistance (DCR)
--Winding material and process: High purity copper material is used as the winding material, combined with advanced winding technology, greatly reducing the DC resistance of the inductor. Low DCR means that the power loss generated when current passes through an inductor is smaller, and less energy is converted into heat energy, improving the efficiency of the inductor. At the same time, it also helps to reduce the power consumption of the entire circuit and extend the battery life of the device, which is significantly effective in portable electronic devices.

4. Good frequency characteristics
--Broadband response: NR inductors can maintain relatively stable inductance performance over a wide frequency range. Whether in the low or high frequency range, it can better meet the circuit's requirements for inductance. In high-frequency switching power supply circuits, it can effectively suppress high-frequency noise, ensuring the stability and reliability of the circuit under high-frequency working conditions.

--High self resonant frequency: NR inductors have a high self resonant frequency, which allows them to maintain their inductance characteristics near the self resonant frequency without experiencing a sharp decline in performance due to capacitive effects. This feature broadens its application range in high-frequency circuits, such as in RF circuits, where it can be used for signal processing and filtering.
