MALVERN, PA — Vishay Intertechnology Inc. (NYSE: VSH) has expanded its ILHB series of automotive-grade multilayer chip ferrite beads, increasing current-handling capacity and broadening design options for manufacturers facing growing electromagnetic compatibility (EMC) requirements in automotive, industrial and communications equipment.
The expanded product line includes additional package sizes, higher current ratings and a wider range of impedance values, allowing engineers to address noise-filtering requirements across a broader set of power and signal applications.
Vishay’s ILHB series is now offered in 0402, 0603, 0805, 1008 and 1206 case sizes with current ratings up to 6 amps and impedance values ranging from 10 ohms to 2,700 ohms.
The company indicated the expanded lineup can deliver two to three times the current-handling capability of previous configurations while maintaining comparable package sizes and impedance characteristics.
The components are designed to reduce electromagnetic interference in systems that require high-current filtering, including automotive power-management systems, industrial automation equipment, telecommunications infrastructure, computing hardware and medical devices.
Vishay also updated the product documentation to include additional performance metrics intended to simplify component selection and reduce the need for engineers to consult multiple frequency-response charts during the design process.
The enhanced specifications include impedance peak values, peak-frequency data, impedance roll-off characteristics and crossover-point information used to evaluate bead performance across operating frequencies.
The devices are qualified to the AEC-Q200 automotive reliability standard and utilize silver inner conductors with copper, nickel and tin plating.
The ferrite beads operate in temperatures ranging from minus 55 degrees Celsius to 125 degrees Celsius and comply with RoHS and halogen-free environmental standards.
