The "TSL2 Series" is a high-frequency reactor primarily used for the removal of high-frequency components superimposed on circuit current, as well as for storing magnetic energy and controlling the rise and fall of circuit voltage. It is compact and lightweight, making it suitable for research and experimental applications, as well as for integration into devices. 【Features】 - Standardized high-frequency inductor as a core component - Short delivery time products - Compact and lightweight - Usable for research, experimental applications, and integration into devices - V-shaped types can also be manufactured *For more details, please refer to the catalog or feel free to contact us.

The "water-cooled reactor" is encapsulated in an aluminum case to accommodate water cooling, and miniaturization is achieved by molding it with a highly thermally conductive resin. It can also be used by attaching it to forced air cooling fins. Since it is encapsulated in an aluminum case, it has high weather resistance and excellent quietness. By molding with a high thermal conductivity resin, it becomes possible to dissipate more heat than conventional designs, allowing for an increase in copper and iron losses, which enables miniaturization. 【Features】 ■ Miniaturization of the reactor is possible by designing with increased copper and iron losses. ■ Cooling plates can also be manufactured by our company. ■ High weather resistance and excellent quietness. ■ It can also be used by attaching it to forced air cooling fins. ■ Cooling plates can also be manufactured by our company. *For more details, please refer to the PDF document or feel free to contact us.

The "ring-shaped air-core reactor" has a structure without an iron core inside the winding and is used in high-frequency reactors, etc. Since there is no magnetic saturation of the iron core, the inductance value does not change even when exceeding the rated current. Additionally, the frequency characteristics are also good. It is used in cases where high-frequency iron loss becomes a problem. 【Features】 ■ Structure without an iron core inside the winding ■ Used in high-frequency reactors, etc. ■ Inductance value does not change even when exceeding the rated current due to the absence of magnetic saturation of the iron core ■ Good frequency characteristics ■ Used in cases where high-frequency iron loss becomes a problem *For more details, please refer to the PDF document or feel free to contact us.

The "high-frequency reactor" is used in DCAC inverters and DCDC converters and is also referred to as a power inductor. By selecting the appropriate core based on frequency bands, low loss is achieved. The winding adopts a vertical winding with good high-frequency characteristics, allowing for excellent heat dissipation and miniaturization. We manufacture reactors with current values and inductance values tailored to customer requirements. As standard products, we also offer immediate delivery of the TSL series, which has excellent DC superimposition characteristics. 【Features】 ■ Appropriate cores are selected based on frequency bands to achieve low loss ■ The winding employs a vertical winding with good high-frequency characteristics, enabling excellent heat dissipation and miniaturization ■ Molded types can also be produced by encapsulating in an aluminum case and molding with a high thermal conductivity resin, achieving high heat dissipation *For more details, please refer to the PDF document or feel free to contact us.

This product is a reactor that allows for easy adjustment of the inductance value (L value) by moving the iron core up and down through handle operation. Since it can change a wide range of L values with a single unit, it is possible to reduce costs and labor by preparing several types of reactors and switching terminals. The L value is changed by varying the gap of the iron core; moving the iron core upward decreases the L value, while moving it downward increases the L value. It has a proven track record for use in DC testing of low-voltage switching devices (JIS C8201-5). 【Features】 ■ Capable of changing a wide range of L values with a single unit ■ Reduces costs and labor by allowing terminal switching ■ Proven track record for DC testing of low-voltage switching devices ■ Custom design options available beyond proven products *For more details, please refer to the PDF document or feel free to contact us.

The "current-limiting reactor" is a product used in AC circuits connected in series to limit the short-circuit current during a short-circuit fault. It is used for protection during short circuits in facilities such as power receiving equipment. It must withstand the enormous short-circuit current both electrically and mechanically, which is why it is built robustly. While providing mechanical and thermal protection, it also aims to reduce the breaking capacity of the circuit breakers in the power receiving equipment. 【Features】 ■ Connected in series in AC circuits ■ Limits short-circuit current during faults ■ Reduces the breaking capacity of circuit breakers in power receiving equipment ■ Robust construction ■ Must be fixed with a separate insulating structure during installation *For more details, please refer to the PDF document or feel free to contact us.

The "Power Inductor for Large Current Smoothing" features a ferrite core with excellent frequency characteristics and a flat rectangular winding coil (edgewise coil), making it suitable for high frequency and large current applications. The heat resistance class is F. We offer two models: "AG1341" with an inductance of 3.5μH and "AG1391" with 27μH. 【Features】 ■ Usable for high frequency and large current ■ Heat resistance class is F *For more details, please refer to the related link page or feel free to contact us.
