Chokes deliver common and differential mode in one SMD for DC power line apps
Bourns, Inc. announced two new low-profile, high current series of compact surface mount common mode chokes. The new SRF1206A and SRF9045A series provide not only common mode but also differential mode filtering in a single choke configuration. These highly robust products offer high current capacity to answer the need for components that meet board space constraints in an increasing number of […]
Driving brushed and brushless DC motors
DC motors are available in various electrical configurations and, except for brushless DC (BLDC) motors, are relatively simple devices. As a result, driving brushed DC motors is a relatively simple process. As shown below, BLDC motors require a more sophisticated approach. A “motor drive” is not even necessary with brushed dc (BDC) motors in some […]
Compact flat-wire SMT chokes carry high currents
TDK Corporation has extended its portfolio of EPCOS ERU SMT power inductors with the ERU16 choke series, comprised of ten different types. The inductance values of the new B82559B*A016 series, which replaces the former B82559AA016 series, extend from 1.0 µH to 30 µH, and their saturation currents range from 10.3 A DC to 40.4 A […]
