Featuring a flat wire design that is coiled and mounted directly to the circuit board to allow efficient heat dissipation, the new DR79892 and DR79893 flat-wire inductors from Datatronic Distribution are designed for performance in power supplies, industrial controls, and instrumentation applications. Flat wire inductors are well suited for power-supply applications where high temperatures often affect performance. Their compact flat-wire design provides for better thermal management, which results in superior performance and reliability. The unique design of the Model DR79892 and DR79893 allows heat to dissipate quickly, which provides sufficient cooling to maintain performance. The DR79892 and DR79893 inductors are insulated to a minimum of 100 M? at 500 V AC between coil and core. Rated to insulation class E, they are operable to a high temperature of 120 °C. These design characteristics make them useful for equipment produced for use in heavy-duty commercial or rugged industrial environments. The Model DR79892 flat-wire inductor features an inductance of 4.0 μH and a rated inductance of 2.5 μH. It offers a 45-A rated current, a 0.8 m? maximum DC resistance, and 500-V-AC isolation between coil and core. The size of these inductors is 16 x 29 x 29.5 mm (width, length, and seated height). The Model DR79893 flat-wire inductor features an inductance of 45 μH and a rated inductance of 40 μH. It offers a 30-A rated current, a 4.0 ? maximum DC resistance, and 500-V-AC isolation between coil and core The size of these inductors is 29 x 43 x 50 mm (width, length, and seated height). In 10,000-piece quantities, the Datatronic DR79892 flat-wire inductors are available beginning at $3.50 each, and the DR79893 flat-wire inductors in 10,000-piece quantities are available beginning at $7.60 each. Lead-time is stock to six weeks. Volume OEM pricing is available upon request. Datatronic Distribution
