en.Wedoany.com Reported - Vishay Intertechnology, Inc. has expanded its ILHB series of automotive-grade multilayer chip ferrite beads for high-current filtering. The series now offers higher current ratings, smaller package sizes, and a wider impedance range to cover more electromagnetic compatibility (EMC) noise reduction applications.

With the expansion, the series is now available in package sizes including 0402, 0603, 0805, 1008, and 1206, with rated currents up to 6 A and impedance values ranging from 10 Ω to 2700 Ω. At the same package size and impedance value, the new devices offer two to three times the current capability of previous products, enabling designers to achieve higher current handling in smaller packages.

With a broader combination of sizes, currents, and impedance values, the ILHB series ferrite beads are suitable for a wide range of EMC noise reduction scenarios, 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 electronics, white goods, medical equipment, avionics, and telecommunications infrastructure.

To simplify device selection, the ILHB product datasheet now includes several design parameters, such as impedance peak (Zpk) and its corresponding frequency (F at Zpk), the frequency at which impedance drops below the nominal value above 100 MHz (F at ZDO), and the inductive reactance (X) versus resistance (R) frequency crossover point (XL/XR crossover). With these parameters, engineers can estimate bead performance at more frequencies without reviewing multiple performance charts. The datasheet also defines the rated current as the DC current that causes a 40°C temperature rise at a 20°C ambient temperature.

The ILHB series devices are AEC-Q200 compliant, with inner conductors made of silver (Ag) and plated with copper (Cu), nickel (Ni), and tin (Sn). These ferrite beads operate over a temperature range of -55°C to +125°C and are RoHS-compliant, halogen-free, and Vishay Green products.

Samples and production quantities of the ILHB ferrite beads are available now, with a standard lead time of 8 to 10 weeks.
