Low-Profile, High-Current Power Inductors


Offered in 1212 Case Size, Devices Feature Low Profiles Down to 0.8 mm

and Wide Range of Inductance Values from 0.33 µH to 10 µH

Malvern, April 5, 2016 — Vishay Intertechnology announced that it has extended its IHHP series of low-profile, high-current power inductors with two new devices in the compact 3 mm by 3 mm 1212 case size. Offering a wide range of inductance values from 0.33 µH to 10 µH and low profiles of 0.8 mm and 1.0 mm, respectively, the Vishay Dale IHHP-1212ZH-01 and IHHP-1212AZ-01 are designed to save space and increase efficiency in portable electronics.

The devices released today are optimized for DC/DC converters and power supply modules for notebook PCs, tablets, and other handheld, battery-powered electronics. The magnetic-alloy power inductors offer low acoustic noise and provide magnetic shielding to prevent interference with nearby components.

The IHHP-1212ZH-01 and IHHP-1212AZ-01 feature maximum DCR down to 23 mΩ, high saturation current to 6.5 A, and a heat rating current up to 6.0 A. The devices operate over a temperature range from -55 °C to +125 °C and are packaged in an RoHS-compliant, 100 % lead (Pb)-free shielded construction.
