Malvern, Pa. Vishay Intertechnology, Inc. claims to introduce the industry's first series of low-profile, high-current inductors with a 3% direct current resistance (DCR) tolerance for current sensing applications. The IFLP4040DZ01 inductors offer saturation currents up to 36 amps and a low DCR of 0.88 milliohm in a 4040 footprint.
The IFLP4040DZ01 inductors feature compact dimensions of 0.40 in. x 0.40 in. with a very low maximum height profile of 0.157 inch. They occupy the standard 4040 footprint shared by lower-profile inductors with a 20% lower DCR. The inductors are specified for saturation currents ranging from 20 A to 36 A, and inductance values from 0.34 uH to 0.62 uH. Standard inductance tolerance is ±20%.
Featuring a low 0.88-milliohm DCR and ferrite as its core material, the IFLP series offers high efficiency that enables less power drain on power-limited battery systems, eliminating core-loss increases over time, and giving end-users reliable, long-term performance, said the company.
The IFLP inductors handle high transient current spikes without hard saturation and operate at a frequency up to 5 MHz. Packaged in a RoHS-compliant, 100% lead-free shielded construction, the devices are specified for an operating temperature range of 55°C to 125°C with high resistance to thermal shock, moisture, mechanical shock, and vibration.
With the lowest DCR/uH for their respective package sizes, according to the company, the IFLP inductors serve as high-performing, space- and power-saving solutions for voltage regulator module (VRM) and dc-to-dc converter applications in end products including mobile devices, notebooks, desktop computers, servers, graphic cards, portable gaming devices, personal navigation systems, personal multimedia devices, and automotive systems. Typical applications include low-profile, high-current power supplies and point of load (POL) converters, distributed power systems, and field-programmable gate arrays (FPGAs).
Pricing: For U.S. delivery only, pricing is $0.55 each in quantities of 10,000.
Availability: Samples and production quantities of the IFLP4040DZ01 inductors are available now. Lead time for production quantities is eight to ten weeks.
