The temperature of component (ambient temperature plus temper-ature * for bi-polar current applications divide Bpk (as calculated above) by 2. rise) must be within the specified operating temperature range. 5. Optional Tape & Reel packaging can be ordered by adding a "T" suffix 2.The maximum current rating is based upon temperature rise of the to the part number (i.e. PA1005.020 becomes PA1005.020T). Pulse component and represents the DC current which will cause a typical complies to industry standard tape and reel specification EIA481. temperature rise of 40°C with no airflow when both one turn windings 6. The "NL" suffix indicates an RoHS-compliant part number. Non-NL sufconnected in parallel. fixed parts are not necessarily RoHS compliant, but are electrically and 3. To calculate value of terminating resistor (Rt) use the following formula: mechanically equivalent to NL versions. If a part number does not have Rt (Ω) =VREF * N / (Ipeak_primary) the "NL" suffix, but an RoHS compliant version is required, please con4. The peak flux density of the device must remain below 2000 Gauss. To tact Pulse for availability. calculate the peak flux density for uni-polar current use following formula: Mechanical RECOMMENDED PAD LAYOUT 4 Schematic .050 1,27 .073 1,85 xxx 3 5 .050 1,27 .120 3,05 .060 1,52 2 1 6 .106 2,69 Pin 1 .010 0,25 .330 8,38 MAX Pin 8 BOTTOM VIEW 6 1 5 2 4 3 Pin 7 7 3 Iprimary Isecondary 1 N RT Vref APPLICATION CIRCUIT .073 1,85 NOM .284 7,21 MAX *NOTE: for RoHS compliant part, the height is increased to: .024 0,61 1 .100 2,54 .190* 4,83 NOM .006/0,15 8 SURFACES 8 .200 5,10 NOM & .215 5,50 MAX Weight . . . . . . . . . . . . . .0.34 grams Tray . . . . . . . . . . . . . . . . . .120/tray Tape & Reel . . . . . . . . . . . .900/reel Coplanarity . . . . . . . . .0.004 inches Dimensions: Inches mm Unless otherwise specified, all tolerances are ± .010 0,25 USA 858 674 8100 • Germany 49 7032 7806 0 • Singapore 65 6287 8998 • Shanghai 86 21 54643211 / 2 • China 86 755 33966678 • Taiwan 886 3 4641811 www.pulseeng.com 110 SPM2007 (6/08)
