MALVERN, Pa. — Sept. 19, 2022 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has expanded its IHHP series of low profile, high current power inductors with three new devices in compact 0603, 0805, and 0806 case sizes. Combining low DCR and core losses with a low maximum height of 0.8 mm, the Vishay Dale IHHP-0603ZH-01, IHHP-0805ZH-01, and IHHP-0806ZH-01 are designed to save space and increase efficiency in Internet of Things (IoT) devices and portable electronics.
The devices released today are optimized for DC/DC converters and power supply modules for notebook PCs, tablets, IoT, 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-0603ZH-01, IHHP-0805ZH-01, and IHHP-0806ZH-01 feature maximum DCR down to 24 mΩ, high saturation current to 5.2 A, and a heat rating current up to 4.9 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, composite powdered iron alloy construction.
