OP-01 / PRODUCT INFORMATION

High-Frequency Transformer

This toroidal common-mode inductor uses a high-permeability ring core, tightly wound heavy-gauge enamelled copper wire and an insulated mounting base. The source describes low magnetic leakage, favorable impedance characteristics and high-current capability for suppressing common-mode noise. It also describes stable filtering, heat resistance and a sturdy structure suitable for direct PCB mounting, with EMI filtering in power equipment as a typical application.

PRODUCT DETAILS

Product overview.

The original catalog places this listing under High-Voltage Transformers while naming it High-Frequency Transformer. Its summary describes a common-mode inductor and its detailed text describes a toroidal transformer. The translated descriptions are retained below; confirm the component type and operating specifications before selection.

Detailed transformer description

The toroidal transformer uses a ring-shaped iron core and all-copper windings in a toroidal construction. The source describes lower magnetic leakage, noise and heat generation, and higher conversion efficiency compared with conventional EI transformers. Insulation wraps the exterior, with multicolored insulated leads for step-up or step-down voltage conversion. Typical uses include line-frequency isolation supplies providing stable AC voltage for audio amplifiers and industrial control equipment.

Features described in the source

Toroidal core: low magnetic leakage and electromagnetic interference, with very low operating noise.
High conversion efficiency: low copper and core losses, low temperature rise and stable continuous operation.
All-copper enamelled-wire windings: stable output voltage and strong load capability.
Compact construction: smaller and lighter than rectangular EI transformers at the same power level, according to the source description.
Insulation protection: outer insulation wrapping and heat-resistant leads for electrical isolation.
Convenient mounting: the center opening allows screw fastening.

Application examples

Audio: Hi-Fi amplifiers, professional stage sound systems and high-power audio supplies.
Industrial control: instrumentation, security equipment and medical-equipment power supplies.
Energy and storage systems: power control cabinets and isolated power modules.
Lighting: high-power landscape lighting and industrial lighting supplies.
Household equipment: massage equipment and isolated supplies for high-power appliances.
Export equipment: voltage conversion and isolation for different national power grids.
