New Inductors Feature Space-Saving 0402 and 0603 Case Sizes With SRF up to 6900 MHz and Q Factor to 43

Vishay Adds to IMC Family of Wirewound, Surface-Mount Inductors With New Devices Intended for Compact Communications Systems

MALVERN, PENNSYLVANIA - December 17, 2004 - Vishay Intertechnology, Inc. (NYSE: VSH) today extended the IMC family of wirewound, surface-mount inductors from Vishay Dale with the release of two new devices packaged in compact 0402 and 0603 case sizes and designed to provide space savings in communications applications with limited board space.

Intended for end systems including cellular phones, cable modems, ADSL, repeaters, Bluetooth devices, and other electronic devices, the new IMC-0402-01 and IMC-0603-01 respectively feature dimensions of 0.039 in. by 0.022 in. [1.00 mm by 0.55 mm] with a 0.020 in. [0.5 mm] height profile and 0.063 in. by 0.041 in. [1.60 mm by 1.05 mm] with a height profile of 0.041 in. [1.05 mm].

The new wirewound inductors feature advances such as higher self-resonant frequencies (SRF), better Q factors, and more stable performance. The IMC-0402-01 offers SRF values ranging from 2100 MHz to 6000 MHz over an inductance range of 1.0 nH to 47.0 nH and improved minimum Q factor values from 26 to 13. For the IMC-0603-01, SRF values range from 1000 MHz to 6900 MHz over a broad inductance range of 2.0 nH to 270 nH, and minimum Q factor values range from 43 to 16.

Rated DC current ranges from 150 mA to 1360 mA for the IMC-0402-01 and 170 mA to 700 mA for IMC-0603-01. Tolerances as low as ±2% are available for devices with inductance ratings of 10 nH and up.

The new IMC inductors are rated for an operating temperature range of −40 °C to +125 °C and a storage temperature of −40 °C to +125 °C. Their lead (Pb)-free, surface-mount construction enables easy assembly with excellent solderability and resistance to soldering heat. Both devices are suitable for reflow soldering and are available in tape-and-reel packaging for automatic handling.

Samples and production quantities of the new wirewound, surface-mount inductors are available now. Lead time for production quantities is nine weeks.
