Vishay’s IHLE high-current inductors with integrated e-shields for improved EMI protection are now available in commercial and automotive-grade devices in the 5050 case size

Vishay
Intertechnology, Inc. has extended its IHLE series of low-profile, high-current
inductors featuring integrated e-shields to reduce electromagnetic interference
(EMI) with new commercial- and automotive-grade devices in the 5050 case size. By
eliminating the need for separate board-level Faraday shielding, the Vishay
Dale IHLE-5050FH-51 and IHLE-5050FH-5A inductors lower costs and save
board space.

These
new devices include the electric and B field associated with EMI in a
tin-plated copper integrated shield, providing up to –20 dB of electric field
reduction at 1 cm (above the center of the inductor) when the integrated shield
is connected to ground, said Vishay. Other features include high-temperature
operation to 155°C and coplanarity of the four terminals within ≤100 µm.

The
inductors are optimized for energy storage in DC/DC converters up to 2 MHz and
provide excellent attenuation of noise in high-current filtering applications
up to the SRF of the inductor. Applications for the IHLE-5050FH-51 include
servers and desktop PCs; high-current POL converters; low-profile, high-current
power supplies; and battery-powered devices. The AEC-Q200–qualified
IHLE-5050FH-5A targets automotive engine and transmission control units, diesel
injection drivers, noise suppression for motors, windshield wipers, power
mirrors and seats, entertainment/navigation systems, heating and ventilation blowers,
and LED and HID lighting.

The
inductors offer high resistance to thermal shock, moisture, and mechanical
shock and handle high transient current spikes without saturation. In addition,
the 100% lead-free shielded, composite construction reduces buzz to ultra-low
levels. The IHLE-5050FH-51 and IHLE-5050FH-5A are RoHS-compliant, halogen-free,
and Vishay Green.

Samples
and production quantities are available with lead times of nine weeks for large
orders. Pricing for U.S. delivery starts at $0.90 per piece in quantities of
10,000.
