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 4,3 mm. The parts are magnetically shielded by magnetic resin, minimising any possible magnetic interference. The inductors’ low DC resistance and high rated current contribute to the efficiency of the power supply circuit. The series ranges from a 1,0 μH model with DC resistance 0,009 Ω, to a 100 μH model with DC resistance 0,436 Ω. 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).
