CMT-SERIES
Common Mode Inductors
(Through-Hole)
Description
• Four sizes of through-hole off-line
common mode inductors
RoHS
2002/95/EC
• Inductance range from 0.53 - 66 mH
• Current range up to 6.5 Amps
• Noise attenuation up to 68 dB
• Frequency range up to 6 MHz
• Meets UL94V-0 flammability standard
• Ferrite core material
Applications
• Protects AC input from effects of switching regulators
• Off-line power supplies
• EMI filters
• DC-DC converters
• Computer, TV, VCR, audio and office equipment
Environmental Data
• Storage temperature range: -40°C to +125°C
• Operating ambient temperature range: -40°C to +85°C
range is application specific. The internal “hot-spot”
temperature defines the maximum allowable currents,
which are limited to 130°C, including ambient.
Packaging
• Supplied in bulk packaging
