Space-Saving Devices Combine Operating Temperatures to +125 °C With Profiles as Low as 1.0 mm for Computer and Telecom Applications

MALVERN, Pa. — Nov. 13, 2019 — Vishay Intertechnology, Inc.today introduced three new commercial IHLP® low profile, high current inductors in the 3.3 mm by 3.3 mm 1212 case size — the company’s smallest to date. Designed to save space in computer and telecom applications, the Vishay Dale IHLP-1212AZ-01, IHLP-1212AB-01, and IHLP‑1212BZ-01 offer extremely low profiles down to 1.0 mm.

The devices released today are optimized for energy storage in DC/DC converters up to 5 MHz, and provide excellent attenuation of noise in high current filtering applications up to the SRF of the inductor. Applications for the inductors include notebooks, desktops, and servers; low profile, high current power supplies; and distributed power systems and FPGAs.

Packaged in a 100 % lead (Pb)-free shielded, composite construction that reduces buzz to ultra low levels, the IHLP-1212AZ-01, IHLP-1212AB-01, and IHLP-1212BZ-01 offer high resistance to thermal shock, moisture, and mechanical shock, and handle high transient current spikes without saturation. The devices are RoHS-compliant, halogen-free, and Vishay Green.
