LQH31HNR88K03L - Brand New Murata Electronics Fixed Inductors
-
Description
The LQH31HNR88K03L is a fixed inductor component model used in electronic circuits. It is designed to provide a constant current for driving white LEDs. The device can drive two, three, or four LEDs in series from a Li-ion cell. By using series connection, the LEDs can have identical currents, ensuring uniform brightness without the need for ballast resistors. With a switching frequency of 1.2 MHz, the LQH31HNR88K03L allows for the use of small external components. Additionally, it only requires a small output capacitor, as small as 0.22μF, saving space and cost compared to other solutions. The LQH31HNR88K03L also features a low 95mV feedback voltage, resulting in minimal power loss and better efficiency when using a current setting resistor.
