Vitec Electronics Corp. today introduced the 59P901X series of inductors as the first in the industry to guarantee a tight tolerance of ±10% for direct current resistance (DCR). This feature is required for accurate current sensing across the inductor to set precision droop, channel current balancing and over-current protection.
The 59P901X series DCR is also the lowest offered in this package (7 mm x 10 mm x
5 mm) making it the most efficient inductor offered to the VRM and the VRD industry for server, workstation, desktop, video cards and portable applications.
The unique ferrite core material and geometry, combined with a staple winding, provide for a robust and low cost design capable of handling currents up to 55 amps peak and operating frequencies as high as 2 MHz without the thermal aging concerns associated with the competing powder iron based inductors.
The three inductors are available in 1,000 pieces per 13-inch reel and are priced at $0.28 each in quantities of 100,000. Samples and small pre-production quantities are available from stock with a production lead time of four weeks.
