SMT Inductors Target DC/DC Converters

Available in five different model families, the miniature Model DR333-7 Series of surface-mount filter inductors are space-efficient devices designed for use in dc/dc converter power supplies. The devices feature high-energy storage capacity to provide effective filtering of ripple in the input or output channels of the power supply. With a frequency range of 0.1 MHz to 10 MHz and a wide selection of standard inductance values and current ratings up to 3.6A, the inductors are said to be very effective in filtering second and third order harmonics of the ripple frequency in dc/dc converter power supplies rated at 50W and lower. Designed for automated assembly processes, the oval-shaped inductors are compatible with pick and place equipment and high-temperature soldering processes.
