T9*5*3-200uH Magnetic Core Inductor 30A High Current Toroidal Power
Inductor
1.Product Description
The 200 uH high current ring power inductor, as a key component in
the field of power electronics, achieves diverse and important
functions with its unique performance and carefully selected
materials, and is widely used in various circuits.
1.High inductance precision and stability: The nominal inductance
is 200 μ H, providing stable and specific inductance values for the
circuit. In circuits such as switch mode power supplies, this
inductance can effectively store and release energy, ensuring
efficient conversion and transmission of electrical energy.
Moreover, under different working conditions, its inductance
fluctuation is minimal, which can maintain stable circuit
performance, such as ensuring normal operation of the circuit even
under temperature and current changes.
2. Excellent high current carrying capacity: Designed to carry high
currents, it can easily handle currents of several amperes or even
tens of amperes. By adopting special winding design and
high-quality magnetic cores, inductance saturation is avoided when
the current is too high, ensuring stable operation in high load
circuits such as industrial motor drives and high-power switching
power supplies.
3. Low DC resistance (DCR): With low DC resistance characteristics,
it greatly reduces heat loss when current passes through and
improves inductance efficiency. Low DCR means that when
transmitting high currents, the loss of electrical energy converted
into heat energy is reduced, energy waste is reduced, the energy
efficiency of the entire circuit is improved, and the service life
of equipment is extended.
4. Excellent frequency response: Maintain good performance over a
wide frequency range, effectively handling both low and high
frequency signals. In high-frequency switching power supplies, it
can quickly respond to current changes, suppress high-frequency
noise, and ensure stable and pure output signals.
5. Low electromagnetic interference (EMI): The annular structure
concentrates magnetic flux, significantly reduces electromagnetic
leakage, and lowers electromagnetic interference to surrounding
circuits. At the same time, it also has strong resistance to
external electromagnetic interference, enhancing the
electromagnetic compatibility of the circuit, and is suitable for
equipment with strict electromagnetic environment requirements.

2.Key materials
1. Magnetic core material
--Ferrite core: a commonly used material with high magnetic
permeability, which can effectively concentrate magnetic fields and
improve inductance performance. It has low loss, especially
performs well at high frequencies, and can reduce energy loss and
heat generation. Suitable for scenarios with high requirements for
high-frequency performance, such as switching power supplies and
high-frequency circuits.
--Pomo alloy magnetic core: It has extremely high magnetic
permeability and can provide high inductance values under low
magnetic fields. Commonly used in circuits that require strict
inductance and precise control of magnetic fields, such as
precision measuring instruments and power circuits for high-end
audio equipment.
--Iron silicon aluminum magnetic core: It has good magnetic
permeability and saturation magnetic flux density, can withstand
large currents, and is not easily saturated under high currents. At
the same time, it has good temperature stability and low loss,
suitable for circuits with high current and high temperature
environments, such as industrial motor drives, automotive
electronics, and other fields.
2. Winding material: High purity copper wire is usually used
because of its high conductivity, which can reduce resistance and
minimize power loss when current passes through. For high current
applications, large-diameter wires or multi stranded wires are used
to increase the conductive area, reduce skin effect, and further
enhance the high current transmission capacity.
3. Insulation material: Insulation materials such as polyester
film, polyimide tape, etc. are used to isolate the winding from the
magnetic core and between each turn of the winding. These materials
have good electrical insulation performance and high temperature
resistance, ensuring stable operation of inductors in high current
and high voltage environments, and preventing faults such as short
circuits.
