    IN STOCK - MORE THAN 100 READY TO SHIP!
    VISHAY DALE - ITU-1731-4 High Current Toroid Inductor Copper Coil Horizontal Mount 50uH 40A Toroid inductance coils are important electrical components for preventing electromagnetic interference, widely used in supply circuits, miniature TVs, adapters, DC-DC power modules, various electronic products, etc. The advantage of the toroidal shape is that, due to its symmetry, the amount of magnetic flux that escapes outside the core (Leakage Flux) is low, therefore it is more efficient and thus radiates less Electromagnet Interference (EMI). Large Low Loss, Ferrite Core with stable electrical operating characteristics maximize inductor efficiency by minimizing copper losses High-Reliability Low-Resistance Leaded Inductor. Toroid Cores are Self Shielded requiring no need for an enclosure. Inductance: 50uH Current: 40Amp. Inductance @ 1Vrms, 10Khz, 40Amps DC: 50uH min. Inductance @ 1Khz w/out DC: 60uH DC-Resistance: 0.01 Ohms. Wire Diameter: 1.83mm (0.071") 11 AWG Core Material: Ferrite Dimensions: 2.2" Diameter x 1.1" High. Connections: Quick Connect or PCB Solder Mounting. Note: Leads are approximately 1" Long and some have 1/4" Quick Connects attached. Operating Temperature: -55°C to 125°C Extremely Conservative Design Current Rating. We counted about 64 turns of 13AWG Enameled Magnet Wire on this High Current Toroid Choke designed to rid audio equipment noise from the lights and props used on a commercial stage. Applications: Applications: EMI Filters, Buck and Boost Switches, Ballasts, Medical, Telecommunications, Musical Instruments, Industrial Controls, Chokes, Power Supplies, Inverters, Amplifiers and Control Circuits.
