Product type
Power inductors are passive electronic components that store energy in a magnetic field when electrical current flows through them. They are typically made from a coil of wire wound around a magnetic core, which can be composed of materials such as ferrite or iron powder. Power inductors are commonly used in various electronic circuits to filter signals, smooth out current, and manage power supply in devices.
| Inductance range | 1 µH to 10 mH |
| Current rating | Up to 100 A |
| DC resistance | Typically 0.1 to 100 mΩ |
| Core material | Ferrite or iron powder |
| Operating temperature | -40°C to +125°C |
When selecting a power inductor, consider the inductance value, current rating, and DC resistance to ensure compatibility with your circuit requirements. It's also important to specify the operating temperature range and core material based on your application. Be sure to inquire about certifications and tolerances, as these can affect performance and reliability. Quantities should be discussed based on your production needs.
