Vishay – New low-profile, high-current power inductors


IHHP power inductors: built-in magnetic shielding to avoid interference with other components

Vishay Intertechnology has extended its IHHP series of low-profile, high-current power inductors with two new devices in the 3mm x 3mm 1212 case size.

The IHHP-1212AZ-01 and IHHP-1212ZH-01 inductors help designers of portable electronics devices in particular to save space and increase power efficiency.

The inductors contain a magnetic alloy power choke coil. They produce low levels of acoustic noise, and provide magnetic shielding to prevent interference with nearby components.
