Product type
A drum core inductor is a type of passive electronic component that stores energy in a magnetic field when electrical current passes through it. Typically constructed with a coil of wire wound around a magnetic core, these inductors are designed to provide high inductance values in a compact form factor. The drum shape allows for efficient magnetic coupling and minimizes losses, making them suitable for various applications in electronic circuits.
| Inductance range | 1 µH to 10 H |
| DC resistance | Low resistance values typically from a few milliohms to several ohms |
| Core material | Ferrite or iron |
| Operating temperature | -40°C to +125°C |
| Rated current | Up to several amperes depending on the design |
When selecting a drum core inductor, consider the required inductance value, DC resistance, and rated current for your specific application. It's important to specify the operating temperature range and any environmental conditions the inductor will face. Additionally, inquire about the core material and any certifications that may be relevant to your industry standards.
