Vishay Intertechnology Inc. has introduced a couple of IHLP low-profile, high-current inductors in the 2020 case size. Supporting operating temperatures up to 155°C and offering low profiles down to 3mm, the Vishay Dale IHLP-2020CZ-51 and automotive-grade IHLP-2020CZ-5A offer inductance values from 0.22-15uH, detailed the company.

Vishay IHLP inductors

With a frequency range up to 1MHz, the devices serve as high-performing, space- and power-saving solutions for voltage regulator modules (VRM) and DC/DC converters in high-temperature commercial and automotive applications. End products for the IHLP-2020CZ-51 include servers; notebooks; low-profile, high-current power supplies and point of load (POL) converters; and distributed power systems.

The AEC-Q200-qualified IHLP-2020CZ-5A is optimised for engine and transmission control units, diesel injection drivers, entertainment and navigation systems, noise suppression for motors, windshield wipers, HID and LED lighting, heating and ventilation blowers, and power seats and mirrors.

The IHLP-2020CZ-51 and IHLP-2020CZ-5A handle high transient current spikes without hard saturation. Packaged in an RoHS-compliant and 100 per cent 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.

Samples and production quantities of the inductors are available with lead times of 10 to 12 weeks for large orders.
