Vishay Introduced Commercial IHLP High Current Inductors with High Operating Temperatures

Space-Saving Devices Feature Profiles as Low as 1.0 mm for Computer and Telecom Applications


MALVERN, Pa. — Dec. 5, 2019 — Vishay Intertechnology, today introduced three new commercial IHLP low profile, high current inductors with high operating temperatures up to +155 °C 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-51, IHLP-1212AB-51, and IHLP-1212BZ-51 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-51, IHLP-1212AB-51, and IHLP-1212BZ-51 offer high resistance to thermal shock, moisture, and mechanical shock, and they handle high transient current spikes without saturation. The devices are RoHS-compliant, halogen-free, and Vishay Green.
