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.
