Vishay Intertechnology introduced three new Automotive Grade IHLP low profile, high current inductors in the company’s smallest automotive-qualified case size to date: the 3.3 mm by 3.3 mm 1212. Designed to save space in next-generation ADAS and sensor applications, the Vishay Dale IHLP-1212AZ-5A, IHLP-1212BZ-A1, and IHLP-1212BZ-5A combine high operating temperatures of up to +155 °C with extremely low profiles down to 1.0 mm.
The AEC-Q200 qualified devices released today are optimized for energy storage in DC/DC converters up to 5 MHz. They also provide excellent attenuation of noise in high current filtering applications up to the SRF of the inductor. With their high operating temperatures, the inductors are designed for filtering and DC/DC conversion in ADAS, sensor, and entertainment/navigation systems, in addition to noise suppression for medium current filter applications.
Packaged in a 100 % lead (Pb)-free shielded, composite construction that reduces buzz to ultra-low levels, the IHLP-1212AZ-5A, IHLP-1212BZ-A1, and IHLP-1212BZ-5A offer high resistance to thermal shock, moisture, and mechanical shock, and handle high transient current spikes without saturation. The devices are RoHS-compliant, halogen-free, and Vishay Green.
