MALVERN, Pa. — Sept. 19, 2016 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of low-profile, high-current inductors for high-frequency VRM10.0 applications. Offered in the 2727, 4027, 4031, and 5151 case sizes, Vishay Dale IFLR series devices offer high saturation current to 71 A, very low DCR to 0.26 mΩ, and inductance down to 0.072 µH.
With a frequency range up to 2 MHz, the inductors released today 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.
Device Specification Table:
|Inductance (µH)||0.072 to 0.150||0.085 to 0.220||0.170 to 0.215||0.21 to 0.44|
|DCR max. (mΩ)||0.35||0.42||0.29||0.35|
|Heat rating current (A)||45||50||61||50|
|Saturation current (A)||30 to 58||33 to 70||44 to 60||35 A to 71 A|
Samples and production quantities of the IFLR series are available now, with lead times of 12 weeks for large orders.
