50/60 Hz Current Sense Transformer
CS2106

  • For measuring current from 0.5 to 20 Amps rms
  • 0.1 Volt per Ampere sensitivity (with terminating resistance of 68 Ohms)
  • 2500 Vrms isolation (hipot), one minute between windings
  • May also be used to measure 400 Hz line currents
  • Applications include sensing branch circuit overload and detecting load drop or shutdown
  • RoHS-compliant. Tin-silver over tin over nickel over copper terminations.

1 Inductance is for the secondary, tested at 1 kHz, 0.1 Vrms.
2 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
3 Square wave response deteriorates above and below this frequency.
4 Use the following equation to determine the approximate change in output voltage/ input ampere when varying the terminating resistor: Vout / Iin = 0.1 × (RT / 68).
5 Ambient temperature range: −40°C to +85°C
6 Storage temperature range: Component: −40°C to +85°C
Packaging trays: −40°C to +80°C
7 Electrical specifications at 25°C
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
