By using an advanced metallized-film on the polypropylene dielectric, the GLI power capacitors are claimed to have the industry's highest RMS current rating. They also offer a longer service life compared to aluminum electrolytic capacitors, and feature a reliability rating of 300FIT.

The GLI capacitors provide an inductance of <30nH and are intended for dc-linking, voltage-conversion, frequency-conversion, and impulse-discharge applications. The capacitors are suitable for use in in traction and industrial drives, UPS systems, and other power electronics applications.

Vishay has also released a new line of surface-mount, multilayer ferrite-bead models and NTC-leaded thermistor assemblies.

The 0402, 1210, 1806 and 1812 ILBB ferrite-beads feature an operating temperature range of -40C to 125C and a nickel barrier coating that increases reliability by eliminating silver migration.

Designed to reduce EMI in telecommunications, computer and automotive applications, the ILBB ferrite beads have impedance values ranging from 31 ohms to 600 ohms at 100MHz. Maximum dc resistance ranges from 0.3 ohm to 1 ohm, with rated dc currents from 50mA to 400mA.

The NTC thermistor assemblies have a curve tracking tolerance range from 0.2c to 1c, with temperatures from -20C to 100C. Tolerance options from 1 percent to 10 percent are available. Standard resistance values for the thermistor component range from 50 ohms to 1 megohm, with 10 curve options.

They are designed for temperature measurement, control, and compensation applications in automotive and medical systems, instrumentation, and consumer products.
