Product type
Ferrite core inductors are passive electronic components that store energy in a magnetic field when electrical current flows through them. They are made from ferrite materials, which are ceramic compounds consisting of iron oxide mixed with other metallic elements. These inductors are widely used in various electronic circuits to filter signals, store energy, and manage power supply applications.
| Core material | Ferrite |
| Inductance range | 1 µH to 10 H |
| DC resistance | 0.1 Ω to 100 Ω |
| Rated current | 100 mA to 10 A |
| Operating temperature | -40°C to +125°C |
When choosing a ferrite core inductor, consider the inductance value required for your application, as well as the rated current and DC resistance. It's important to specify the operating temperature range to ensure reliability in your environment. Additionally, inquire about any relevant certifications or standards that may apply to your industry, and determine the quantity needed for your project to get accurate pricing.
