Compact power inductors for DC-DC converters
AEC-Q200 certified and specified for operation from -55°C to +155°C, the HA74 series is aimed at automotive designs such as high-density converters and pi filters for ADAS (Advanced Driver Assistance System) controllers. The shielded inductors ensure low EMI and are highly resistant to corrosion.
The maximum height of 2.05mm allows designers to create slimline modules for applications where height is a critical parameter. The 5.5mm x 5.5mm footprint, with current ratings up to 2.9A and DC resistance down to 74mΩ, enables high power density and energy efficiency.
With 3MHz switching capability, allowing use in high-frequency converter designs, these compact inductors are an ideal companion to the small high-frequency filter capacitors and help minimise module size and weight. TT’s low-loss metal-alloy core composition ensures high efficiency and low heating at elevated frequencies.
The HA74 family comprises 10 parts covering standard inductance values from 4.7µH to 33µH and current ratings from 1.2A to 2.9A. Semi-custom inductors conforming to individual customer specifications are also available, to special order.
