New Vishay Intertechnology Composite-Coupled Inductors Built on IHLP® Technology for SEPIC DC/DC Converters and Common Mode Applications

Press release date: Feb 05, 2014

Featuring Magnetic Coupling > 90 % in Compact 4040 Case Size, Devices Are Available With Eight Inductance Values From 2.2 µH to 47 µH

MALVERN, Pa. — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced the first devices in a new series of composite-coupled inductors, built on the company's IHLP® technology, for use in SEPIC DC/DC converters, and other applications. Offered in the compact 4040 case size, the Vishay Dale IHCL devices feature two inductors in the same package with magnetic coupling > 90 %, high-temperature performance to +155 °C, and are available in eight inductance values ranging from 2.2 µH to 47 µH.

With a frequency range up to 5.0 MHz, the devices released today are optimized for SEPIC converter circuits in automotive LED lighting. By integrating two inductors in one compact 10.16 mm by 10.67 mm package with a low 4.0 mm profile, the IHCL devices allow engineers to design more compact, robust, and efficient SEPIC converter circuits while lowering overall costs. The IHCL series can also be used for common mode applications.

The new inductors handle high transient current spikes without hard saturation. Packaged in an RoHS-compliant, 100 % lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra-low levels, the devices are specified for an operating temperature range of -55 °C to +155 °C, with high resistance to thermal shock, moisture, mechanical shock, and vibration.
