Coils & Inductors
20 products
Coils and inductors are passive electronic components that store energy in a magnetic field. They play a critical role in power supplies, filter circuits, oscillators, and RF applications. This category includes various types such as toroidal core inductors, SMD power inductors, RF chokes, rod core inductors, and air core coils.
When selecting an inductor, consider parameters like inductance value (µH, mH), saturation current (Isat), DC resistance (DCR), operating frequency, and physical size. Using an inductor with insufficient saturation current can lead to excessive current draw and inefficiency. High-frequency applications demand specially designed inductors to minimize core losses.
Common Coil and Inductor Types
- Toroidal Inductors: Doughnut-shaped ferrite or iron powder core offers high efficiency and low electromagnetic interference.
- SMD Inductors: Surface-mount, compact design suitable for automated assembly processes.
- Power Inductors: Used in high-current circuits such as DC/DC converters and LED drivers.
- RF Inductors: Used in radio frequency circuits for filtering and impedance matching.
To select the right product, evaluate your operating frequency, current requirements, and PCB space constraints. Especially in power circuits, do not overlook temperature rise and magnetic saturation risks.
