1R5 SMD Power Inductor Flat Copper Wire Coil Magnetic Shielding Integrated Inductor

1.Product Description

The 1R5 SMD power inductor (1.5 μ H) is a square surface mount inductor with a flat copper wire winding and built-in magnetic shielding structure. It has low DC resistance (DCR) and high current carrying capacity, and is suitable for high-frequency switch circuits. Its closed magnetic circuit design effectively suppresses electromagnetic interference (EMI), improves system stability, and is resistant to high temperatures (-40 ° C to+125 ° C). It is suitable for digital amplifiers, DC-DC converters, and high-density power modules, balancing high efficiency and compact packaging (such as 5x5mm or 7x7mm), and is suitable for industrial, automotive electronics, and consumer applications.

1. Efficient flat copper wire design: Using flat copper wire winding to reduce skin effect and direct current resistance (DCR), improve current carrying capacity, and reduce energy loss.

2. Magnetic shielding structure: Integrated closed magnetic circuit design effectively suppresses electromagnetic interference (EMI), avoids affecting surrounding circuits, and improves system stability.

3. High temperature resistance: With a wide operating temperature range (-40 ° C~+125 ° C, some models can reach+150 ° C), it is suitable for high-power and high-temperature environments.

4. Compact SMT package: Standard SMD square design (such as 5x5mm or 7x7mm) saves PCB space and is suitable for high-density circuit layout.

5. High reliability applications: Suitable for high-frequency switching circuits such as digital amplifiers and DC-DC converters, supporting industrial, automotive electronics, and consumer devices, and complying with RoHS/AEC-Q200 standards.

2.Function

Summary of the two core functions of 1R5 SMD Power Conductor:

1.Efficient energy storage and conversion
As the core energy storage component of switching power supplies (such as DC-DC Buck/Boost circuits), efficient energy conversion is achieved through a 1.5 μ H inductance value, reducing power loss and improving system efficiency.
Flat copper wire design reduces high-frequency losses, supports fast charging and discharging, and is suitable for high-frequency (above 500kHz) digital amplifiers (Class-D) and other scenarios.

2.Electromagnetic interference (EMI) suppression
The integrated magnetic shielding structure effectively suppresses high-frequency noise and magnetic field leakage, reduces interference with surrounding sensitive circuits (such as RF or signal processing modules), and ensures stable system operation.
The closed magnetic circuit design meets EMC requirements and is suitable for harsh environments such as automotive electronics and industrial power supplies.

In short, it has dual functions of efficient power processing and electromagnetic compatibility optimization.
