Frequently Asked Questions

Q: What is a ferrosilicon aluminum inductor and why is it used in inverters?

A: A ferrosilicon aluminum inductor (also known as a sendust core inductor) uses a composite magnetic core made from iron, silicon, and aluminum. This core material offers very low core losses at high frequencies, excellent DC bias characteristics, and strong resistance to magnetic saturation. These properties make it especially well-suited for sine wave inverter circuits, where stable inductance under varying load currents is essential for producing a clean, accurate output waveform.

Q: Which inductance value should I choose — 25µH or 45µH?

A: The choice depends on your inverter's switching frequency and filter design requirements. A higher inductance (45µH) provides greater filtering and is typically used where more ripple current suppression is needed at lower switching frequencies. A lower inductance (25µH) is suitable for higher switching frequency designs where less inductance is needed for effective filtering. Consult your circuit's design specifications to determine the correct value for your application.

Q: What current rating do I need for my application?

A: This inductor supports a wide current range from 100A to 450A, making it versatile for both medium and high-power systems. Select a rating that matches or comfortably exceeds the peak current your inverter or converter circuit will draw. Operating the inductor within its rated current ensures optimal performance and longevity.

Q: Is this inductor compatible with solar inverter systems?

A: Yes. This ferrosilicon aluminum power inductor is widely used in solar inverter and off-grid power systems due to its high current handling capability, low losses, and thermal stability. It is compatible with most sine wave inverter topologies used in solar and battery-backed power applications.
