The IHLP6767GZ (17 mm X 17 mm X 7.0 mm) is the largest, highest current composite SMD power inductor on the market. With standard inductance values up to 22 µH and current handling capability out to 100 A, this AEC-Q200-qualified component is perfect for high-filter applications or dc-to-dc converters.
The IHLP2020 series (5 mm X 5 mm X 3.0 mm) is a cost-effective alternative to the IHLP2525 series. This inductor is one-third smaller than the standard IHLP2525, yet handles approximately 85% as much current as the larger part. This IHLP2020 is also available in 2.0-mm and 1.2-mm profiles for low- profile applications where a high-current filter or dc-to-dc energy storage inductor is needed.
Vishay’s new “IHLP Core Loss Calculator” is a free tool that assists designers in selecting the proper IHLP inductor based on the operating conditions of their circuit. This tool will simulate the losses in the inductor, including core and both AC and DC copper losses. The temperature rise and final component temperature will also be predicted based on the estimated losses. This tool will allow designers to compare several different inductors, both in size and value, to assist in the selection process. The calculator can be used for buck, boost and buck/boost style converters.
The calculator requires only six inputs: input voltage, output voltage, output current, frequency, ambient temperature and inductance. The calculator will do the rest based on these inputs. Inductance can be selected by using the “radio” buttons on the left hand side.
All designs should be verified in circuit as this tool is for simulation only.
