The new 23S00 bobbin wound surface mount inductors are low DC resistance devices that are designed for use in switching power supplies, power line filter circuits and DC-DC converter applications. Inductance values for the series range from 2.2μH to 220μH (1kHz rms 100mVAC) making the devices compatible with a wide range of off-the-shelf chip sets.
Maximum continuous DC current ratings start at 0.25A for the 220μH devices, increasing to 2.1A for the 2.2μH parts, while corresponding maximum DC resistance values range from 2.28Ω to just 0.019Ω.
Requiring a maximum PCB footprint of only 5.6 × 6.2mm and featuring a board-mounted profile only 3.2mm, the new inductors are particularly suited to applications where space is at a premium. The integral EMI shield further helps to reduce board space by allowing the inductors to be mounted in close proximity to other components.
The new inductors will operate at temperatures from 40 to 85 ° C and are supplied in tape-and-reel packaging.
