Miniature chip coils reduce DC power-circuit noise

1 November 2006 Passive Components

Murata’s tiny wire-wound chip coils, the LQH32C range, with low DC resistance and high current capacity make cleaning up EMI noise from power supply circuits easier.

This extensive family of ferrite core inductors benefits from exclusive winding techniques developed by Murata. Combined with special Murata materials, they provide many options on a 3,2 x 2,5 mm footprint 2,0 mm high, with 1,55 mm (nom.) option for those with especially difficult height limits. Nominal inductance values range from 1,0 μH to 560 μH. There are rated currents up to a full 1,0 A and DC resistances down to 0,06 Ω.

The designs exhibit low voltage drop and little change in inductance with temperature. They also have superior resistance to soldering heat and can be flow or reflow soldered.
