MALVERN, Pa. — June 10, 2026 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced an expansion of its ILHB series of Automotive Grade multilayer chip ferrite beads for high current filtering. The Vishay Dale devices now offer higher current capability, smaller case sizes, and a wider range of impedance values to meet a broader set of EMC noise reduction requirements.
The ILHB series is now available in 0402, 0603, 0805, 1008, and 1206 case sizes with current handling up to 6 A and impedance values from 10 Ω to 2700 Ω. The expanded lineup allows designers to achieve higher current handling in smaller packages, while delivering two to three times the current capability for the same package size and impedance value.
This expanded range of sizes, current handling, and impedance values allows the ILHB ferrite beads to be used in a wider array of EMC noise reduction applications. These include high current, high frequency, and signal-specific filtering in automotive energy distribution and management systems; industrial automation systems; home and building controls; computers and computer peripherals; consumer devices; white goods; medical instrumentation; avionics; and telecom infrastructure.
To simplify device selection, the ILHB product datasheets have also been enhanced with additional design parameters that help engineers estimate bead performance across more frequencies without consulting multiple performance graphs. These parameters include impedance peak value and frequency, the frequency at which impedance drops below the nominal value, and the X- and R-frequency crossover point.
The AEC-Q200 qualified devices feature a silver (Ag) inner conductor with copper (Cu), nickel (Ni), and tin (Sn) plating. The ferrite beads operate over a temperature range from -55 °C to +125 °C and are RoHS-compliant, halogen-free, and Vishay Green.

(1) Rated current is the DC current that causes a 40 °C temperature rise at 20 °C ambient
(2) Zpk = peak of impedance curve
(3) F at Zpk = frequency of Zpk
(4) F at ZDO = frequency above 100 MHz where Z drops to nominal Z
(5) XL / XR x over = crossover point for inductive reactance and resistance impedance
Samples and production quantities of the ILHB ferrite beads are available now, with lead times of 8 to 10 weeks.
