Vishay – IHCL Series: Composite-Coupled Inductors Built on IHLP® Technology



Vishay has 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 2.2µH to 47µH.

With a frequency range up to 5.0MHz, the devices are optimized for SEPIC converter circuits in automotive LED lighting. By integrating two inductors in one compact 10.16mm by 10.67mm package with a low 4.0mm 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-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.
