Chip inductors replace wire-wound inductors
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.
The LQH6PP_43 series is designed to reduce cost, since chip inductors' structure is said to allow them to be constructed more cost efficiently than traditional wire-wound power inductors.
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 6 x 6 x 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 0.009O, to a 100µH model, with DC resistance 0.436O. Allowable DC current, based on inductance change within 30% of nominal, is 7.50A (for 1.0µH part) to 0.92A (for 100µH part).
