Toroid Inductor
- Model: Customize
Main Power's toroid inductors deliver high Q, low EMI, and compact size on ferrite or iron-powder cores for switching supplies, servers, and EV chargers.
Main Power provides several types of Toroid Choke.
A toroid inductor, wild used in electronic circuits, is an insulated coil that is wire wound on a ring-shaped form which is made of different materials, such as, powdered iron, ferrite or another material. Toroid inductors have more inductance per turn and carry more current than solenoids with a core of similar material and size. Toroidal inductors can be used as a toroidal coil, common mode inductors, SMT inductors or for any circuit that might require toroid coils.
- Small size
- Excellent Characteristics for high Q Small size (volume and weight)
- Lower electromagnetic interference (EMI)
- Near complete magnetic field cancellation
- Lower resistance (shorter length per turn)
- Variety of mountings and configurations
Main Power Electric Co., Ltd. has manufactured toroid inductors for more than 30 years under a systematic quality management program, with UL1446 Class B and Class F insulation system certification. We design and build these components at our headquarters and manufacturing facility in Taoyuan City, Taiwan, and ship worldwide, backing every order with custom circuit design and EMI/EMC solution support. Each toroid inductor winds an insulated coil on a ring-shaped core of powdered iron, ferrite, or other materials, so it carries more inductance per turn and more current than a solenoid of similar size, with near complete magnetic field cancellation and lower resistance from its shorter wire length per turn.
Main Power supplies these toroid inductors as toroidal coils, common mode inductors, and SMT inductors, each customized in mounting and configuration for the target circuit. Their small size, high Q, and lower EMI suit switching mode power supplies, chargers, inverters, servers, telecom devices, and medical equipment, as well as solar energy converters, energy storage systems, electric cars, EV chargers, alarm systems, LED lights, AV equipment, TVs, and neon signs.
Q: Why should I choose a Main Power Electric toroid inductor over a standard solenoid inductor?
A: A toroid inductor from Main Power delivers more inductance per turn and carries more current than a solenoid of similar material and size. Because the insulated coil winds on a ring-shaped core of powdered iron, ferrite, or other materials, the design achieves near complete magnetic field cancellation, lower EMI, and lower resistance from its shorter wire length per turn.
Q: What mounting options and customization capabilities does Main Power Electric offer for toroid chokes?
A: Main Power manufactures toroid inductors on a fully customized basis, in a variety of mountings and configurations. We supply toroidal coils, common mode inductors, and SMT inductors, each built to the core material, dimensions, and electrical characteristics the circuit requires.
