CMC Series SMD Ring Core Chokes

TDK CMC Series SMD Ring Core Chokes feature a low height and compact design with superior EMI suppression characteristics. These current-compensated ring core double chokes offer a range of approximately 0.4% to 1.2% stray inductance for differential-mode interference suppression. The B82720S0 chokes also offer a 1.8A rated current at +40°C and 0.88mH nominal inductance. The B82721S0 type features 2.7A to 5.6A rated current at +40°C and nominal inductance from 0.22mH to 3mH. The B82722S0 chokes have a 3.25A to 19A rated current at +40°C with 0.16mH to 5.6mH nominal inductance. TDK CMC Series SMD Ring Core Chokes are constructed with sector windings and a ferrite core with epoxy coating. They are RoHS compatible and suitable for reflow soldering. Applications include suppression of common-mode interferences, DC/DC power converters, low voltage, and more.
