High-current bead inductors

15 May 2013 Passive Components

New from Murata are the 3000A and 3000B series of low-profile power inductors for use in noise reduction circuits of high-frequency and high-current switching power supplies, DC-DC converters and voltage regulator modules.

The 3000A series is available with 80, 100, 150 or 200 nH inductance values; maximum rated peak current is 57 A for the 80 nH device. Typical Rdc is only 0,20 mΩ across the series. The 3000B series has inductance values of 85, 100, 120, 150 or 200 nH and a maximum rated current of 78 A for the 85 nH inductor. Rdc is typically 0,29 mΩ.

Using a low-loss core material, combined with low series resistance (Rdc), gives the inductors a high overall efficiency. The low inductance values suit high-frequency applications while their compact, low-profile dimensions (7,1 x 7,0 x 4,96 mm for the 3000A series) are ideal for designs where available board space is at a premium.

Both series are available in surface mount packages suiting high-volume manufacturing.
