Document 369 -1 Current Sense Transformers T6522-AL AEC This low cost transformer is designed for up to 300 kHz + Q200 85C and above to sense continuous currents up to 3 Amps. The current windings can be connected in series to provide twice the output sensitivity. It offers 500 Vrms interwind- ing isolation. The small footprint, low profile, surface mount ceramic case makes it ideal for high-density boards and provides an excellent surface for pick and place operations. Applications include power supply feedback control, mo- tor protection, overload sensing and detecting load drop or shutdown.

When ordering, please specify packaging code: Typical Response (with R = 50 Ohm) T T6522-ALD 3.0 Packaging: 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 2.5 and trailer ( 25 charge). Series Parallel B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need 2.0 for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D. 2. The two primary windings may be connected in parallel (1 : 50) to provide 1.5 up to 3 A (I ) sensing capability (3 V ), or connected in series (2 : 50) to in out provide twice the sensitivity (1 A I yields 2 V . in out) 1.0 3.
