Core advantages of Surface mount inductor

1. The iron-silicon-aluminum magnetic core has its own distributed air gap. Under high current conditions, the inductance decays gradually. Compared with ferrite magnetic cores, it is less likely to experience magnetic saturation, making it highly suitable for PFC energy storage and power BUCK-BOOST main circuits.
2. The ring-shaped structure's magnetic field is mostly enclosed within the magnetic ring, with little leakage to the outside. This reduces electromagnetic interference to the surrounding PCB components, which is beneficial for the overall EMI performance.
3. The iron-silicon-aluminum material has a high Curie temperature, and its magnetic performance decays minimally under high-temperature conditions. The temperature rise is controllable during long-term full-load operation, making it suitable for power supply continuous operation conditions.
4. The inductance, copper wire diameter, number of turns, and insulation sleeve can all be adjusted as needed. The inductance tolerance supports ±5% and ±10%, allowing for matching of different current and inductance requirements.
5. Coarse copper wires can be selected to reduce DCR (direct current resistance) and copper loss, improving power conversion efficiency and reducing heat generation.

Why choose us

Q: What material is the T050-125 magnetic ring inductor made of?
A: The core material is iron-silicon-aluminum (Sendust) magnetic powder core, with a magnetic permeability of 125 μ. It has a ring-shaped structure without a core and the winding is made by wrapping enameled copper wire.

Q: What is the range of inductance for T050-125?
A: The standard value can be 10 - 180 μH; the actual sensitivity is determined by the number of turns, and the tolerance can be ±5% or ±10%.

Q: What is the rated current of T050-125?
A: The standard is 2 - 7 A; the current size is determined by the copper wire diameter, the thicker the wire diameter, the greater the current-carrying capacity and the smaller the DC resistance DCR.

Q: What are the advantages of the T050-125 iron-silicon-aluminum compared to iron oxide ferrite magnetic rings?
A: It has a built-in distributed air gap, stronger anti-magnetic saturation ability, and the inductance decays more smoothly under large currents; the high-temperature magnetic performance is more stable, suitable for power energy storage circuits.

Q: How is the leakage magnetic field performance of T050-125?
A: The ring has a closed magnetic circuit, with less leakage magnetic field, low electromagnetic interference to the outside, which is conducive to the EMI of the entire machine; compared to the open-air-gap EE and RM frame inductors, the leakage magnetic field is lower.
