DSMD type choke on RSMD ferrite core

SMD chokes features excellent soldering ability and heat resistance. Available in various sizes. Mainly used for noise suppression for power supply, especially for DC-to-DC converters, DC to AC inverters. The SMD chokes showed below are only part of what we offer. Most SMD chokes are being made according to customer specifications or specifications drafted by our designers according to customer required parameters.
