Sumida Announces SMD High-Current Power Inductors for On-Board Chargers

­Sumida America has introduced the CDPQ****/T150 Series of high-current power inductors. In this new design, a combination of precision flat-wire windings and large tinned copper surface mounting pads maximizes current handling capacity. These inductors are magnetically shielded, AEC-Q200 qualified, and a good match for on-board chargers.

The flat wire coil is closely wound together to increase its effective cross-sectional area. This coil is encased in a high permeability ferrite core minimizing physical size. The high surface area of the flat-wire windings is also effective at minimizing internal resistance at high frequencies.     

The CDPQ2014/T150 is available in three inductance values from 1, 2.2, and 3.3 µH. Maximum saturation current ranges from 16 to 48 amps at 150° C. The larger CDPQ2717/T150 is of a similar design and is available in three inductance values of 2.2, 3.3, and 4.7 µH. Its maximum saturation current range is from 16 to 48 amps at 150°C. The absolute maximum voltage across the inductor is 300Vdc for each. Operating temperature is -40 °C to +150 °C (including the device’s self-temperature rise). Other values are also available for OEM orders.

Applications include use as a buck/boost inductor for Onboard Chargers (OBC) in electric vehicles (xEV), DC-DC converters, point-of-load converters, computer peripherals, LED drivers, class D audio amplifiers, and other general high-performance power applications.

The CDPQ2014/T150 is (HWD) 14.5x21.4x23.5 mm. The CDPQ2717/T150 is 16.5x27.5x27.5 mm. The devices are RoHS-compliant and halogen-free.  Solder reflow temperature to 260 °C peak.  Complies with IPC/JEDEC Moisture Sensitivity Level 1, for unlimited floor life at ≤30 °C/85% RH.  

Full application engineering support is available.

Sumida CDPQ2014/T150 and CDPQ2717/T150 Series power inductors are available for sampling.
