CA - Common Mode Toroids - CAB, CAV, CAF, CAX, CAO.

 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 requirements of EN138100, VDE0565, part2: 1997-03 and UL1283
  • 1500 VAC, 50 Hz withstanding voltage for 60 seconds minimum
  •  Competitive pricing due to high volume production
  • Manufactured in ISO-9001 approved facility
  Common Mode Toroidal Chokes

Applications

  • Power Line Filtering
  • EMI/RFI Suppression in Switch Mode Power Supplies
  • Power supplies

Notes:


1) Inductance measured at 25 °C ±5 °C and 10 kHz.
  • L < 2 mH test level < 2.5 mA
  • L > 2 mH test level < 250 mV
2) Inductance loss < 10% by DC preload with In (current compensated).
3) DC Resistance measured at 25 °C ±5 °C.
4) Test voltage per VDE 0565/2.
5) 250 VAC Nominal Operating Voltage.
6) Maximum Ambient Temperature: 60 °C.
