Document 204 Backlight Inductors – DO1607B Series The low profile DO1607B Series has the high breakdown voltage ratings required for backlight applications. Only 2,49 mm high, they have a footprint of 6,6 × 4,5 mm. These inductors are constructed of high temperature materials that provide excellent heat deflection to prevent damage during solder reflow. Standard inductance values range from 1 to 6.8 mH and custom values are available to meet specific requirements. Coilcraft Designer’s Kit C335 contains samples of each of the standard parts shown.
