Vishay Intertechnology Inc. has developed what it claims to be the first winged low-profile, high-current inductor. Designed to be placed on a cut-out PCB, the IHLW-5050CE-01 offers designers a high-current solution using a larger part, without exceeding a profile of 1.2mm on either side of the PCB.

With a frequency range up to 5MHz, the new IHLP inductor serves as a high-performing, space- and power-saving solution for voltage regulator module and DC/DC converter applications in end products including next-generation mobile devices; notebooks, desktop computers, servers, graphic cards, portable gaming devices, personal navigation systems, personal multimedia devices, and automotive systems; low-profile, high-current power supplies and point of load converters; distributed power systems; and FPGAs.

The IHLW-5050CE-01 offers an inductance range from 0.10?H to 10?H, a saturation current range from 14A up to 84A, typical DCR from 0.8m? to 30.4m?, and maximum DCR from 0.96m? to 34.0m?.

The winged inductor handles high transient current spikes without hard saturation. Packaged in an RoHS-compliant, 100 percent Pb-free shielded, composite construction that reduces buzz noise to ultralow levels, the device is specified for an operating temperature range of 55C to +125C, with high resistance to thermal shock, moisture, mechanical shock and vibration.

Samples and production quantities of the new inductor are available now, with lead times of 10 to 12 weeks for large orders.
