"We will wind anything"


If you can conceptualize it, draw it, sketch it or describe it,we can wind it for you.
Sure enough, if you have an engineering print of it, we can serve you even better

CM SERIES : 1 AMPS TO 24 AMPS SMALL SIZE TOROIDAL COMMON MODE INDUCTOR

CM Series: 1 Amps to 24 Amps Common Mode Choke
  • Separated windings for minimum interwinding capacitance
  • Single layer windings for highest common mode impedance over the widest frequency range
  • Spacer provides 3 mm creepage distance for UL, CSA, IEC compliance
  • All materials used are UL94-VO recognized
  • 200 °C insulated solid wires used for high temperature operation
  • Operating temperature: - 40 °C to + 105 °C. Please call factory for 125 °C types
  • Suitable for 100 Khz to 500 Khz
  • Available in both vertical or horizontal mount
