COMMON MODE CHOKES FOR 3-PHASE APPLICATIONS

Nanocrystalline VITROPERM: This is the ideal basis for highest inductance with a low number of turns in extremely compact component volume. VITROPERM chokes are a universal solution for various EMI problems due to the excellent high frequency properties and the stable performance over a wide temperature range.

All below listed standard types in low profile constructions are not moulded and designed for operation in grid connected RFI filters or for applications with higher operating voltages. 

Construction, production and testing of the chokes are in accordance with EN50178, resp. IEC 62109 
The plastic materials comply with the following UL standards:
                UL94            (file number E41871) 
                UL1446       (file number OBJY2.E329745).
Temperature class B (130 °C)

Further information about our CMCs is available in our application note.  

For CMC selections (even at deviant operational data) please download our software tool (requires Microsoft EXCEL):  VAC CMC Quick-Selector . If you cannot find a suitable CMC from the below listed standard range or under further types. three phase, please contact us using our design check lists CMCs acc. to EN50178, resp. CMCs acc. to IEC62109/IEC61800.

The available nanocrystalline tape-wound cores are listed below.   

For testing purposes, VAC offers special sample kits consisting of tape-wound cores Core Sample Kit VITROPERM  and CMCs CMC Sample Kit.

* for Ta < 60 °C

Notes:
IN = nominal current in each winding
Icm = max. permissible leakage or common mode current
UN OVCat III / II  = operating voltage for overvoltage category III / II 
LN = nominal inductance, tolerance +50 % / -30 %
RCu = winding resistance per winding
|Z| = impedance of the choke
fR = resonant frequency of the choke
Ambient temperature Ta   = –40 °C...+70 °C (short-term +90 °C), deviating values are specified in the data sheets.
Operating temperature Top = –40 °C...+130 °C (short-term +150 °C)

Basically, all materials are suitable for operation at -55 °C. We individually confirm this for each choke upon request. The standard chokes are designed for a temperature rise of ΔT = 45….60 K at T= +70 °C and  I = IN in each winding. Data derating is necessary for deviant ambient temperatures or deviant nominal currents. Thus, for example, at lower ambient temperatures the chokes can be operated at higher IN. Please contact VAC for further detailed information.
