C&D Technologies brings five new series of bobbin format surface-mount power inductors. The 4500, 4600, 4700S, 4800S and 4900S series feature an integral ferrite shield to reduce electromagnetic interference (EMI) and are fully compliant with the RoHS directive. The new inductors also comply with the requirements of China RoHS.

The 4500 and 4600 series are suitable for power-line filtering applications. The 4600 series is rated up to 8.7A and offered with inductance values between 0.28µH and 1.0mH. The lower profile 4500 series has the same inductance values and a maximum 8A rating. Both devices have a footprint of 7.3mm x 7.3mm. Overall height is 3.55mm for the 4500 series and 4.55mm for the 4600 series. Operating temperature range is -40ºC to +125ºC.

The 4700S, 4800S and 4900S are single winding alternatives to the 4700, 4800 and 4900 ranges, all are suitable for use between -40ºC and +125ºC. These parts have been designed for use in switching power supply and power-line filter circuits. All share the same 12.2mm x 12.2mm footprint. They all offer the same inductance range of 1.0µH to 1.0mH, but are rated with increasing current levels up to 11.8A, as a result of their differing heights (5.0, 6.0 and 8.0mm respectively).
