Molding Power Choke – MHCB Series MHCB Series MHCB series is designed for low profile type with low RDC and ultra large current. Its molded magnetic shielded type is suitable for high-density mounting and ultra low buzz noise. Soldering conditions can be easily confirmed when mounting onto the board. This series also provides customers with embossed carrier type packaging for automatic mounting machine. Features Applications RoHS compliant High density DC/DC converters Low profile type POL converters Shielded construction High current VRM/VRD for notebook / Server / desktop CPUs Ultra low buzz noise due to molding construction High speed charger For thickness less than 1.2mm, suitable for low profile applications e.g., Ultra thin NB/Monitor/TV/Tablet Product Identification Shape and Dimensions Recommended Pattern Dimensions in mm Dimensions in mm TYPE 06030 A B C 6.6±0.2 6.95±0.35 2.8±0.2 D F TYPE A B C 3.0±0.3 1.6±0.5 06030 3.5 6.05 2.35 Molding Power Choke – MHCB Series Electrical Characteristics Irms Isat RDC (±%) Test Frequency (KHz) (A)Typ.
