Vishay – Low-profile, high-current inductors optimised for high-frequency VRMs


Vishay Intertechnology has introduced a series of low-profile, high-current inductors for high-frequency Voltage Regulator Module (VRM) 10.0 applications

The IFLR series devices offer saturation currents as high as 71A and very low DC resistance values. With a frequency range up to 2MHz, the new inductors serve as high-performance, space- and power-saving solutions for VRMs and DC-DC converters in power supplies and Point-of-Load (PoL) converters.

Featuring a shielded package, the IFLR inductors offer high resistance to thermal shock, moisture, mechanical shock and vibration.
