High frequency and commercial frequency reactors - custom manufactured according to type/application.

At Tsuruta Electric, we manufacture DC/AC/three-phase/single-phase reactors (air core and iron core) tailored to specific applications, ranging from large-capacity products for power systems to communication device components.

■ Capable of manufacturing up to a maximum rated current class of 3000A. We propose optimal designs for the core (silicon steel sheets, Super E, amorphous, Finemet, powdered iron cores, ferrite) and coils tailored to the frequency range, including copper strips, litz wire, and single wire. (1) Considering the structure in terms of IP (Ingress Protection) ratings, we can also provide products that are resistant to harsh environments. (2) Compliance with international standards (IEC/EN/UL, etc.) is available. (3) Direct current superimposition characteristics will be measured. (4) Vibration testing evaluations will be conducted. (5) Slim design is possible. ■ Direct Current Superimposition Characteristics: When a direct current bias flows through an inductor, the permeability decreases as it approaches the saturation point of the magnetic material, resulting in a decrease in inductance value. This characteristic is referred to as direct current superimposition characteristics. The issue with this direct current superimposition current arises when a core with a higher permeability than air is used to achieve a small size with a large inductance. Since cores like iron have a permeability that is significantly greater than that of air, it is possible to achieve a small size with a large inductance.
