Chip inductors miniaturise DC/DC converters
Murata Electronics
LQH6PP\\_43 series chip inductors
Murata's latest series of chip inductors is designed to replace wound inductors in DC/DC converter applications such as in LCD TVs and set-top boxes.
They reduce the footprint of power-supply designs by replacing larger inductors without compromising performance.
The LQH6PP\\_43 series can also help to reduce costs, since the chip inductors' simple structure means they can be constructed more cost efficiently than traditional wire-wound power inductors.
Designed for the miniaturisation of DC/DC converters, 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 1.0uH model with DC resistance of 0.009 to a 100uH model with DC resistance of 0.436.
Allowable DC current, based on inductance change within 30 per cent of nominal, is 7.50A (for 1.0uH part) to 0.92A (for 100uH part).
