High-Current Inductors offer 3% DCR tolerance.
Press Release Summary:
Measuring 0.40 x 0.40 in. with 0.157 in. height profile, Series IFLP4040DZ01 is specified for saturation currents from 20-36 A and inductance values from 0.34-0.62 µH with standard inductance tolerance of ±20%. Featuring 0.88 mW DCR and ferrite as its core material, inductors handle high transient current spikes without hard saturation and operate at frequency up to 5 MHz. Units are housed in RoHS-compliant package and operate from 55 to +125°C.
Original Press Release:
Vishay Announces Industrys First Low-Profile, High-Current Inductors to Offer 3% DCR Tolerance
New IFLP Series of Inductors Offers Saturation Currents up to 36 A and
Low DCR of 0.88 mW in 4040 Footprint
MALVERN, PENNSYLVANIA February 16, 2007 Vishay Intertechnology, Inc. (NYSE: VSH) today announced the industrys first series of low-profile, high-current inductors with a 3% DCR tolerance for current sensing applications.
The IFLP4040DZ01 inductors feature compact dimensions of 0.40in. by 0.40in. [10.16mm by 10.16mm] with a very low maximum height profile of 0.157in. [4.00mm]. They occupy the standard 4040 footprint shared by lower-profile inductors with a 20% lower DCR. The new devices are specified for saturation currents ranging from 20A to 36A, a DCR tolerance of 3%, and inductance values from 0.34 µH to 0.62 µH. Standard inductance tolerance is ±20%.
With the lowest DCR/µH for their respective package sizes, the new 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 next-generation 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).
Featuring a low 0.88-mW DCR and ferrite as its core material, the new IFLP series is the most efficient inductor in its class. Its high efficiency allows less power drain on power-limited battery systems, eliminating core-loss increases over time, and giving end-users reliable, long-term performance.
The new inductors handle high transient current spikes without hard saturation and operate at a frequency up to 5 MHz. Packaged in an RoHS-compliant, 100% lead (Pb)-free shielded construction, the new 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.
Samples and production quantities of the new IFLP4040DZ01 inductors are available now. Lead time for production quantities is eight to ten weeks. Pricing for U.S. delivery only in 10,000-piece quantities is $0.55 per piece.
