Wirewound chip inductors provide low DC resistance

Murata has developed two new ranges of low-profile wirewound chip inductors for use in DC-DC converter applications.

Both the LQH3NP M0 series and LQH3NP G0 series of inductors offer low DC resistance.

This is vital for DC-DC converter applications as it prevents energy dissipation from the inductor, improving the converter's overall efficiency.

The new ranges deliver a good size/performance ratio with low DC resistances of 0.044ohm +/-20 per cent (LQH3NP M0) and 0.08ohm +/-20 per cent (LQH3NP G0).

Their low-profile 1212 size packaging is designed to save space, measuring 3 x 3 x 1mm (LQH3NP G0) or 3 x 3 x 1.5mm (LQH3NP M0).

A wide range of inductances is also available: 1.0 to 100uH for the LQH3NP M0 series and 1.0 to 250uH for the LQH3NP G0 series.

The parts come with high rated currents, up to 2.05A, and feature magnetic shielding as standard.

Operating temperature range is -40 to 85C.
