Document 369 -1 SMT Current Sensor - T6522-AL This low cost transformer is designed for use at 50 kHz to 300 kHz 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 interwinding 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, motor protection, overload sensing and detecting load drop or shutdown.

EIA-481 embossed plastic tape (750 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. 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). Inductance is for the secondary, measured at 100 kHz, 0.1 Vrms. Maximum volt-time product for the secondary. Varying terminating resistance increases or decreases output Voltage/ Ampere according to the following equation: RT = Vout x Nsec / Iin. Electrical specifications at 25C.
