  1. When ordering, please specify packaging code: e.g. T6522-ALD
  2. Inductance is for the secondary, measured at 100 kHz, 0.1 Vrms.
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. 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).
  5. Maximum volt-time product for the secondary.
  6. For specific questions regarding frequency range, please contact us at [email protected].
  7. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT (Ohms) = Vout × Nsec / Iin.
  8. 500 Vrms primary to secondary isolation.


  • RoHS compliant. 260°C compatible. Tin-silver-copper over silver-palladium-platinum-glass frit terminations.


  • D = 13″ machine ready reel. EIA-481 embossed plastic tape (750 per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
RoHS compliant
