Sendust Magnetics Powder Core Market – View in Detailed Research Report
Market Size
Sendust magnetics powder cores are specialized magnetic materials composed of an alloy consisting of 6% aluminum, 9% silicon, and 85% iron. These cores are known for their low core losses, excellent temperature stability, and minimal magnetostriction, which significantly reduces audible noise in electrical applications. Sendust cores exhibit a saturation flux density of around 1 Tesla and tend to lose inductance with increasing temperature.
This property can be leveraged in composite core designs to achieve temperature compensation, making them suitable for switching power supplies, pulse transformers, in-line noise filters, swing chokes, and phase‑fired controller filters (e.g., light dimmers).
- Key Market Statistics:
- Asia‑Pacific is the fastest‑growing region due to the rapid expansion of the electronics and automotive sectors.
- The demand for low‑noise inductors in power electronics is a major growth driver.
- Increasing regulatory requirements for power efficiency are further accelerating market expansion.
