Surface Mount, High Frequency
Current Sense Transformer

  • For use at 50 kHz – 300 kHz
  • Small surface mount package
  • 1 Volt per Ampere sensitivity (sensed current windings in parallel)
  • Output sensitivity is doubled by connecting sensed current windings in series
  • 500 Vrms primary to secondary isolation
  • RoHS compliant. 260°C compatible. Tin-silver-copper over silver-palladium-platinum-glass frit terminations

Packaging:

 

D = 13" reel, machine-ready 
EIA-481 embossed plastic tape (750 parts per full reel).
B = Less than full reel
In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead.
2 The two primary windings may be connected in parallel (1 : 50) to provide up to 3 A (Iin) sensing capability (3 Vout), or connected in series (2 : 50) to provide twice the sensitivity (1 A Iin yields 2 Vout).
3 Inductance is for the secondary, measured at 100 kHz, 0.1 Vrms.
4 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Maximum volt-time product for the secondary.
6 Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT (Ohms) = Vout × Nsec / Iin.
7 Ambient temperature range: −40°C to +85°C
8 Storage temperature range: Component: −40°C to +85°C
Tape and reel packaging: −40°C to +80°C
9 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.
