Chip Inductors replace wire-wound units in DC-DC converters.June 7, 2010 -
Designed specifically for miniaturization of DC-DC converters in LCD TVs and set top boxes, LQH6PP_43 Series features 2424 size casing measuring 6.0 x 6.0 x 4.3 mm. Magnetically shielded units range from 1.0 µH model with DC resistance of 0.009 W to 100 µH model with DC resistance of 0.436W. Allowable DC current, based on inductance change within 30% of nominal, is 7.50 A for 1.0 µH part to 0.92 A for 100 µH part.

Murata's Latest Series of Chip Inductors Replaces Wire-Wound Inductors to Reduce Size and Cost of DC-DC Power Supplies
Hoofddorp, Netherlands: Murata's latest series of chip inductor is designed to replace wound inductors in DC-DC converter applications, reducing the footprint of power supply designs by replacing larger inductors without compromising performance. The LQH6PP_43 series can also help to reduce cost, since chip inductors' simple structure means they can be constructed more cost efficiently than traditional wire-wound power inductors, leading to reduced bill of materials cost for power supplies.
Designed especially for the miniaturisation of DC-DC converters in LCD TV and set top box applications, the LQH6PP_43 series features compact low-profile 2424 size casing - measuring just 6.0 by 6.0 by 4.3mm. The parts are magnetically shielded by magnetic resin, minimising any possible magnetic interference.
The LQH6PP_43 series' low DC resistance and high rated current contribute to the efficiency of the power supply circuit. The series ranges from a 1.0µH model with DC resistance 0.009W, to a 100µH model, with DC resistance 0.436W. Allowable DC current, based on inductance change within 30% of nominal, is 7.50A (for 1.0µH part) to 0.92A (for 100µH part).
