Ÿ
Consumer electronics
Ÿ
Computing & accessories
Ÿ
Residential appliances
Ÿ
Medical accessories
Ÿ
Electronic data processing equipment
Ÿ
Office automation equipment
Ÿ
Industrial applications
Ÿ AMI-27 filters are also available as single stage filters (AMI-22 series).
Ÿ
Machinery
Ÿ Various terminal options allow you to select the desired connection style.
Ÿ
Various noisy application requires good
attenuation performance filter
Ÿ The AMI-27 filters are also available as B versions with no Y-capacitors for
medical applications as well as A versions with low capacitance for safety critical
applications with requirements for low leakage currents.
Ÿ All filters provide a general purpose conducted attenuation performance, based
on chokes with high saturation resistance and excellent thermal behavior.
Ÿ The AMI-27 filter can be use to cover broad range of uses and they offer a good
size/amperage ratio.
