T series

Features and Benefits

Tfilters are designed for easy and fast chassis mounting.
All filters provide a general purpose conducted attenuation performance, based on chokes with high saturation resistance and excellent thermal behavior.
Various terminal options allow you to select the desired connection style.

Typical Applications

Electrical and electronic equipment
Consumer goods
Household equipment
Medical equipment
Electronic data processing equipment
Office automation and datacom equipment
Various noisy applications requiring high filter performance

Typical Filter Attenuation

Per CISPR 17: symmetrical 50 Ω/50 Ω -> Differential Mode (DM); asymmetrical 50 Ω/50 Ω -> Common Mode (CM)
