Five new ranges of power inductors have a compact design that aids their inclusion in applications where PCB real estate is limited and component height is restricted

C and D Technologies has expanded its portfolio of surface-mount power inductors with five new series of bobbin format devices. The 4500, 4600, 4700S, 4800S and 4900S series offer a broad range of inductance values and current ratings to provide design engineers tasked with developing power systems, the maximum amount of choice for their applications.

The new ranges have a compact design that aids their inclusion in applications where PCB real estate is limited and component height is restricted.

All parts feature an integral ferrite shield to reduce electromagnetic interference (EMI) and are fully compliant with the RoHS Directive.

As is the case with the majority of C and D's existing magnetic products, the new inductors also comply with the requirements of China RoHS.

The 4500 and 4600 series are suitable for powerline filtering applications found in consumer electronics equipment such as desktop computers, LED applications and GPS systems.

They are also ideal for use in a wide range of industrial and telecomms applications including network hubs, bridges and routers, and high frequency wireless communication devices.

The 4600 series is rated up to 8.7A and offered with inductance values between 0.28uH and 1.0mH.

The lower profile 4500 series has the same inductance values and a maximum 8A rating.

Both devices have footprints of 7.3 x 7.3mm.

Overall height is 3.55mm for the 4500 series and 4.55mm for the 4600 series.

Operating temperature range is -40 to +125C.

The 4700S, 4800S and 4900S are single winding alternatives to the 4700, 4800 and 4900 ranges, all are suitable for use between -40 and +125C.

These parts have been designed for use in switching power supply and power-line filter circuits.

All share the same 12.2 x 12.2mm footprint and are ideal for any application requiring a high saturation current in a low-profile package.

They all offer the same inductance range of 1.0uH 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).

Compliance with UL94V0 and J-STD-020-C plus tape and reel packaging are common to all of the new parts.
