CA Series • Common Mode Toroidal Chokes
CA Series
common mode toroidal chokes provide an efficient
means of filtering supply lines having in-phase signals of equal
amplitude thus allowing equipment to meet stringent electrical
radiation specifications. Wide frequency ranges can be filtered
by using high and low inductance Common Mode toroids in
series. Differential mode signals can be attenuated substantially
when used together with input and output capacitors.
Features
• Separated windings for minimum capacitance
• Meets requitements of EN138100, VDE 0565, part2: 1997-03
and UL1283
• Competitive pricing due to high volume production
• Manufactured in ISO-9001:2000, TS-16949:2002 and
ISO-14001:2004 certified Talema facility
• Fully RoHS compliant
Electrical Specifications @ 25°C
Test frequency: Inductance measured at 0.10VAC @ 10kHz
Test voltage between windings: 1,500 VAC for 60 seconds
Operating temperature: -40°C to +125°C
Climatic category: IEC68-1 40/125/56

Talema's Engineering staff can assist in the design of other inductance values and sizes.
Notes:
1) Inductance measured at 25°C and 10 kHz.
L < 2mH test level < 2.5mA
L > 2mH test ;evel < 250mV
2) Inductance loss <10% by DC preload
