Summary

COSEL Power Supply, Noise Filter 2025 Product Catalog

2Selection of EMI FiltersEMI/EMCFilterb. Terminal block type: TThese types of EMI filters use a terminal block astheir interface (if the standard product uses aconnector).[Standard Product][Option:T]Figure 2.13.2 Comparison betweenStandard Product and T-option Productc. High permeability choke coil type(ultra low-frequency and ultra high attenuation): HThese types of EMI filters the choke coil core witha high permeability core.These types improve the common mode attenuationcharacteristic for low frequencies compared totheir standard products.Attenuation [dB]0102030405060Standard ProductOption:H70800.010.1110100Frequency [MHz]FTA -100 -104FTA-100-104-HFigure 2.13.3 Example of Comparing Common ModeAttenuation Characteristics betweenStandard Product and H-option Productd. Hexagon socket head cap bolt type: SThese types of EMI filters have a hexagon sockethead cap (Allen) bolt in their terminal block ininstead of the standard bolt (cross recessed(Philips) hexagon head bolt).Customers can select the desired type of bolt fortools they are using.[Standard Product][Option:S]Figure 2.13.4 Comparison betweenStandard Product and S-option ProductTechnical Notes-10? 768 ?e: With switch of line to ground capacitor type : GThese types of Ultra high attenuation type for EU,With switch of line to ground capacitor.Attenuation [dB]0204060801001200.1 1 10 100Frequency [MHz]FTA -50 -683FTA-50-335Figure 2.13.5 Example of Comparing Common ModeAttenuation Characteristics betweenStandard Product and Ultra high attenuationtype for EU ProductFigure 2.13.6 With switch of line to ground capacitor type(Customers use when Test Voltage)f.
