smt current sensor C t6522-al document 369 -1 document 369-1 revised 03/20/07 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 interwind - ing isolation. the small footprint, low profle, 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. to request free evaluation samples, contact coilcraft or visit www.coilcraft.com . 1. when ordering, please specify packaging code: t6522-al d packaging: d = 13 machine ready reel. 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. 2. the two primary windings may be connected in parallel (1 : 50) to provide up to 3 a ( i in ) sensing capability (3 v out ), or connected in series (2 : 50) to provide twice the sensitivity (1 a i in yields 2 v out) . 3. inductance is for the secondary, measured at 100 khz, 0.1 vrms. 4. maximum volt-time product for the secondary. 5. varying terminating resistance increases or decreases output voltage/ ampere according to the following equation: r t = v out n sec / i in . 6. electrical specifcations at 25c. typical application 1 2 5 6 3 4 50 t r t 1t i in v out frequency sensed volt-time r t for part turns (n) 2 inductance 3 dcr max (ohms) range current product 4 1 v out number 1 pri : sec min (mh) 1,2 C 5,6 3 C 4 (khz) max i in (v-sec) from 1 a i in 5 t6522-al_ 1 : 50 3.4 0.006 0.70 50 C 300 3 a 30 50 ohms 0 0.5 1.0 1.5 2.0 2.5 3.0 v out (v olts rms) 0 0.5 1.0 1.5 2.0 2.5 3.0 current (amps rms) pa rallel ser ies typical response (with r t = 50 ohm) us uk t aiwan china singapore +1-847-639-6400 sales@coilcraft.com +44-1236-730595 sales@coilcraft-eur ope.com +886-2-2264 3646 sales@coilcraft.com.tw +86-21-6218 8074 sales@coilcraft.com.cn + 65-6484 8412 sales@coilcraft.com.sg ? coilcraft inc. 2013 this pr oduct may not be used in medical or high risk applications without prior coilcraft appr oval. specification subject to change without notice. please check web site for latest infor mation.
