Small Automotive Grade IHLP Inductors for Under the Hood Applications

Vishay Intertechnology launched a small Automotive Grade IHLP low profile, high current inductors with the 3.3 mm by 3.3 mm 1212 case size to save space in next-generation ADAS and sensor applications. The new Vishay Dale IHLP-1212AZ-A1 and IHLP-1212AB-A1 combine operating temperatures of +125 °C with extremely low profiles down to 1.0 mm, while the IHLP-1212AB-5A features high operating temperatures to +155 °C and a profile of 1.2 mm. The inductors are AEC-Q200 qualified and are optimized for energy storage in DC/DC converters up to 5 MHz.

 

The new IHLP-1212AZ-A1 and IHLP-1212AB-A1 inductors features excellent attenuation of noise in high current filtering applications up to the SRF of the inductor. The inductors can operate in high temperatures up to +155 °C and are a good choice for filtering and DC/DC conversion in ADAS, sensor, and entertainment / navigation systems, in addition to noise suppression for medium current filter applications. The IHLP-1212AZ-A1 and IHLP-1212AB-A1 devices are packaged in a 100 % lead (Pb)-free shielded, composite construction that reduces buzz to ultra-low levels. The IHLP-1212AZ-A1, IHLP-1212AB-A1, and IHLP-1212AB-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.
