Space-saving multilayer chip coils

20 February 2008 Passive Components

The new monolithic chip coil family of power inductors from Murata, the LQM2HP series, features a package size of just 2,5 by 2,0 by 1,1 mm (1008 size). These multilayer power inductors use proprietary ceramic materials and innovative inner electrode design to enable board space savings of up to 44% without performance degradation when compared to wirewound parts.

Aimed primarily at DC-DC converter circuits, the LQM2HP series is suitable for miniaturisation of power supplies in electrical appliances that demand high performance. The inductors feature integral magnetic shielding to eliminate EMI issues.

Parts are available with inductances between 0,47 and 4,7 μH and at rated current up to 1,8 A. Low DC resistance of between 0,04 and 0,12 Ω minimises losses and boosts efficiency.
