Vishay’s New Low-Profile, High-Current Inductors Tailored for High-Frequency VRM10.0 Applications

Vishay Intertechnology

Vishay Intertechnology introduces a new series of low-profile, high-current inductors for high-frequency VRM10.0 applications.

The new Vishay Dale IFLR series devices comes in 2727, 4027, 4031, and 5151 case sizes and offers high saturation current to 71 A, very low DCR to 0.26 mΩ, and inductance down to 0.072 µH.

The new inductors has a frequency range up to 2 MHz and serve as high-performing, space and power-saving solutions for voltage regulator modules (VRMs) and DC/DC converters in notebooks, desktop computers, and servers; and low-profile, high-current power supplies and point of load (POL) converters.

Featuring a 100 % lead (Pb)-free shielded package, the RoHS-compliant devices are specified for an operating temperature range of 40 °C to +125 °C, with high resistance to thermal shock, moisture, mechanical shock, and vibration.
