Mansfield, Mass. C&D Technologies has expanded its portfolio of surface-mount power inductors with the introduction of five series of bobbin format devices. The 4500, 4600, 4700S, 4800S and 4900S series inductors offer a broad range of inductance values from 0.28 μH up to 1.0 mH with top-end current ratings of 8 A to 11.8 A to help design engineers develop their power systems.
The new inductors have a compact design that aids their inclusion in applications where PCB real-estate is limited and component height is restricted, said C&D. All parts feature an integral ferrite shield to reduce electromagnetic interference (EMI) and are fully compliant with the RoHS directive. They also comply with the requirements of China RoHS.
The 4500 and 4600 series are suitable for power-line filtering applications found in consumer electronics equipment such as desktop computers, LED applications and GPS systems. They are also used in a wide range of industrial and telecommunications applications including network hubs, bridges and routers, and high-frequency wireless communication devices.
The 4600 series is rated up to 8.7 A, and is offered with inductance values between 0.28 μH and 1.0 mH. The lower profile 4500 series has the same inductance values and a maximum 8-A rating. Both devices have a footprint of 7.3 x 7.3 mm. Overall height is 3.55 mm for the 4500 series and 4.55 mm for the 4600 series. The operating temperature range is -40°C to +125°C.
The 4700S, 4800S and 4900S are single winding alternatives to the 4700, 4800 and 4900 ranges, and are suitable for use over the operating temperature range of -40°C and +125°C. These parts have been designed for use in switching power supply and power-line filter circuits. All share the same 12.2 x 12.2-mm footprint and are suitable for any application requiring a high saturation current in a low-profile package. They offer the same inductance range of 1.0 μH to 1.0 mH, but are rated with increasing current levels up to 11.8 A, as a result of their different heights (5.0 mm, 6.0 mm and 8.0 mm, respectively). All parts are compliant with UL 94V-0 and J-STD-020-C and are available on tape and reel packaging.
