New IFLP-4040DZ-01 Low-Profile, High-
Current Inductors
The Key Benefits:
Industry's first series of low-profile, high-
current inductors with a 3 % DCR tolerance
Feature compact dimensions of 0.40 in. by
0.40 in. [10.16 mm by 10.16 mm] with a
very low maximum height profile of 0.157 in.
[4.00 mm]
Offer saturation currents ranging from 20 A
to 36 A and inductance values from 0.34 H
to 0.62 H
With a low 0.88-m DCR and ferrite as its
core material, the new IFLP series is the
most efficient inductor in its class
Handle high transient current spikes without
hard saturation
The Key Applications:
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).
The News:
Vishay Announces Industry's First Low-Profile, High-Current Inductors to
Offer 3 % DCR Tolerance With Saturation Currents up to 36 A and Low DCR
of 0.88 m in 4040 Footprint
Vishay Intertechnology, Inc. (NYSE: VSH) announces the industry's first series of low-profile, high-current
inductors with a 3 % DCR tolerance for current sensing applications.
Occupy the standard 4040 footprint shared by lower-profile inductors with a 20 % lower DCR
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 Perspective
: Vishay's new IFLP-4040DZ-01 is the industry's first series of low-profile, high-current
inductors with a 3 % percent DCR tolerance for current sensing applications. With the lowest DCR/H for their
respective package sizes and saturation currents up to 36 A, 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 a
broad range of electronic products.
Availability:
Samples and production quantities of the new IFLP-4040DZ-01 inductors are available now. Lead
time for production quantities is eight to ten weeks.
