Vertical Through-Hole Power Inductor Winding inductor Special Inductor for Buzzer Alarm

        It is designed for vertical installation, occupying minimal PCB space and suitable for compact electronic devices that are sensitive to space. This inductor employs a dual-wire parallel winding technique to ensure the symmetry of the two coils. The central common pin serves as the shared connection point for the two coils and can also be used as a heat dissipation bridge and EMI suppressor.

Core advantages of Inductor

1. The three-legged structure integrates two windings onto the same magnetic core, with the common terminals shared. Compared to using two separate two-legged inductors, DR6×12 can reduce approximately 30% of the PCB area, while also lowering the BOM cost and the number of assembly processes.
2. The intermediate common pin is not only an electrical connection point but also serves as a heat dissipation bridge to conduct the winding heat to the PCB copper foil, and at the same time acts as an EMI suppressor, helping to improve the electromagnetic compatibility of high-frequency circuits.
3. The I-beam inductor adopts an open magnetic circuit structure, and the magnetic core is less prone to saturation. It can still maintain a stable inductance value under transient large current impacts. This characteristic makes it superior to some closed magnetic circuit inductors in boost circuits and DC-DC converters.
4. DR6×12 adopts a vertical compact design, with a body diameter of only 6mm. The I-beam winding structure results in a smaller distributed capacitance of the coil and a higher self-resonant frequency, making it suitable for medium and high-frequency switching power supply scenarios.
5. On the same magnetic core platform, by adjusting the winding turns and wire diameter, a wide range of inductance values from 1µH to 100mH can be achieved, meeting various circuit requirements from signal filtering to power storage.

Why choose us

Q: What are the differences between a 6*12 three-pin inductor and a common two-pin magnetic ring inductor?
A: The two-pin inductor is generally used for single common-mode or differential-mode filtering; the three-pin integrated design enables a single component to simultaneously achieve common-mode + differential-mode EMI filtering, reducing the number of components, saving PCB space, and simplifying the BOM.

Q: Can the 6*12 three-pin inductor undergo dip painting process? What are its advantages and disadvantages?
A: It supports vacuum dip painting. Advantages: Suppresses coil buzzing noise, prevents moisture, and resists vibration; Disadvantages: The cost slightly increases, and the heat dissipation slightly decreases. It is suitable for household appliances and small outdoor power supplies.

Q: How to select between the 6*12 three-pin inductor and the 8*14 three-pin magnetic ring inductor?
A: The 6*12 three-pin inductor is small in size and suitable for small current compact power supplies; the 8*14 magnetic ring is larger and can handle larger currents and be wound with higher inductance.

Q: Can the pin length and pitch of the 6*12 three-pin inductor be modified?
A: Customized pin length and pitch are supported, which can match the layout of your PCB board.

Q: How to choose between the iron-silicon-aluminum and iron-oxide-based two-pin magnetic cores for the 6*12 three-pin inductor?
A: The iron-silicon-aluminum version has good DC bias performance and is less prone to magnetic saturation, suitable for power filtering with DC components; PC40 iron-oxide-based has a higher cost-performance ratio and is suitable for common high-frequency EMI noise suppression scenarios.
