Inductors, also called chokes, coils, or reactors, are passive components designed to store energy in most electrical circuits. These electronic components are integral in several electrical and electronic applications due to their unique property—they oppose sudden increases or decreases in current. An inductor ensures a stable power supply by filtering high-frequency noise, managing current flow, and regulating voltage in complex circuits. They are typically made of a coil of wire, sometimes wrapped around a magnetic core. Inductors are commonly used in analogue and power applications, managing AC signals, smoothing voltage, and protecting sensitive components.
Why Buy an Inductor?
You should buy inductors for several reasons. They not only store energy (in a magnetic field) but also oppose changes in current. They also minimise power losses and maintain signal integrity. In essence, without inductors, many modern electronic devices, ranging from power supplies to communication systems, would be unable to function effectively or efficiently.

Explore our extensive range of premium inductors designed for a variety of applications. Choose from:
- Surface Mount Inductors – Surface mount inductors are a broad category that encompasses multiple inductors mounted directly on PCBs. These space-saving components are used in portable electronics, automotive, and IoT devices with automated assembly compatibility.
- Wire-Wound Surface Mount Inductors – These inductors feature a wire coil wound around a ceramic or ferrite core enclosed in a surface-mount package. They offer higher inductance and current ratings, making them ideal for power supply modules and EMI filtering.
- Multilayer Surface Mount Inductors – They are compact and reliable inductors designed for high-frequency applications. Constructed by layering conductive and insulating materials, these components allow for easy mounting of PCBs.
- Leaded Inductors – Loaded inductors are traditional inductors with leads extending from the component body. They are ideal for through-hole PCB designs, offering high durability and easy prototyping with secure solder joints.
- Coupled Inductors – These components are designed for applications like power transformers and converters, enabling efficient energy transfer between circuits.
- Wireless Charging Coils – These coils are specifically designed for inductive charging applications in wearables, smartphones, and electric tools. They are tailored for efficient energy coupling over an air gap, enabling contactless, cable-free energy transfer.
