603 current sense transformers

WCM603 Series Current Sense Transformer

WCM603 series current sense transformers are an excellent choice for sensing current to 20 amps in a low profile SMD package. Designed for switching power supply applications, they will accommodate frequencies from 100 kHz to 1 MHz with excellent linearity. The product also provides 3000 Vac isolation between the current and sense windings for safety agency compliance.

Notes:

  1. Nominal 100% duty cycle current is approximately half peak value.
  2. For fully optimal performance, operate in recommended areas only. Within these ranges magnetizing current will be less than 1% of peak rated sense current and temperature rise will not exceed 40°C. Check with West Coast Magnetics for operation outside recommended areas.
