Vishay announced an expansion of its ILHB series of Automotive Grade multilayer chip ferrite beads. The ILHB series is now available in 0402, 0603, 0805, 1008, and 1206 case sizes. The devices support current handling up to 6 A and impedance values from 10 Ω to 2700 Ω at 100 MHz. The expansion provides higher current capability in smaller packages and delivers two to three times the current capability for the same package size and impedance value compared to previous offerings.
The AEC-Q200 qualified ferrite beads feature a silver (Ag) inner conductor with copper (Cu), nickel (Ni), and tin (Sn) plating. They operate over a temperature range of -55 °C to +125 °C and are RoHS-compliant, halogen-free, and Vishay Green.
The expanded series targets EMC noise reduction applications, including 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.
Vishay has enhanced the ILHB product datasheets with additional design parameters, including impedance peak value and frequency, the frequency at which impedance drops below the nominal value, and the X- and R-frequency crossover point.
Detailed specifications by case size are as follows:
- 0402: Dimensions 1.0 × 0.5 × 0.5 mm, Z at 100 MHz 10–1800 Ω, DCR max. 18–2400 mΩ, Rated DC current 0.05–3.1 A
- 0603: Dimensions 1.6 × 0.8 × 0.8 mm, Z at 100 MHz 22–2500 Ω, DCR max. 7–1800 mΩ, Rated DC current 0.05–6 A
- 0805: Dimensions 2.0 × 1.2 × 0.85 mm, Z at 100 MHz 17–2700 Ω, DCR max. 10–800 mΩ, Rated DC current 0.2–6 A
-1008: Dimensions 2.5 × 2.0 mm, Z at 100 MHz 300–600 Ω, DCR max. 30 mΩ, Rated DC current 4 A
- 1206: Dimensions 3.2 × 1.6 mm, Z at 100 MHz 19–1000 Ω, DCR max. 10–300 mΩ, Rated DC current 0.5–6 A
Samples and production quantities of the ILHB series ferrite beads are available now, with lead times of 8 to 10 weeks.
