SD Series • High Efficiency Storage Chokes SD Series storage chokes provide excellent efficiency and field modulation when used as loading coils for interim energy storage with switch mode power supplies. The use of MPP cores allows compact size, a highly stable inductance over a wide bias current range and high "Q" with operating frequencies to 200kHz. Features • Operating frequency to 200kHz • Small size and high "Q" • Highly stable inductance with changing bias current • Fully encapsulated styles available meeting class GFK (-40°C to +125°C, humidity class F) per DIN 40040. • Manufactured in ISO-9001:2000, TS-16949:2002 and ISO-14001:2004 certified Talema facility • Fully RoHS compliant Schematic 2 Mounting Style O F V L (µH) Typ. @ Rated Current ±15% N o L o ad DCR mOhms Typical Energy Storage (µJ)1 400 500 630 1000 2000 2500 4000 474 620 820 1157 2695 3080 5625 537 670 563 650 992 730 1000 79 99 12 198 397 496 794 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 15 x 7 15 x 7 15 x 7 19 x 9 20 x 9 26 x 12 26 x 12 17 17 17 22 22 29 29 20 20 20 25 25 30 30 S D __-0.63-6000 6000 7600 1150 1191 1 1 1 30 x 15 32 S D __-1.0-250 S D __-1.0-500 S D __-1.0-1000 S D __-1.0-2500 S D __-1.0-4000 S D __-1.0-6000 S D __-1.6-160 S D __-1.6-315 S D __-1.6-400 S D __-1.6-500 S D __-1.6-1000 S D __-1.6-2500 S D __-1.6-4000 S D __-2.0-63 S D __-2.0-100 S D __-2.0-315 S D __-2.0-630 S D __-2.0-1000 S D __-2.0-1600 S D __-2.0-2500 S D __-2.5-63 S D __-2.5-100 S D __-2.5-160 S D __-2.5-200 S D __-2.5-400 S D __-2.5-1000 S D __-3.15-63 S D __-3.15-100 S D __-3.15-160 S D __-3.15-250 S D __-3.15-630 250 500 1000 2500 4000 6000 160 315 400 500 1000 2500 4000 63 100 315 630 1000 1600 2500 63 100 160 200 400 1000 63 100 160 250 630 323 580 1250 4160 5970 9260 251 443 613 695 1290 3670 5440 81 115 422 885 1387 2420 3240 99 129 241 275 790 1521 80 157 234 570 1122 354 210 290 550 820 970 127 289 266 115 195 380 450 87 161 168 120 145 200 313 62 122 132 70 120 125 62 60 86 85 110 125 250 500 1250 2000 3000 205 408 502 640 1280 3200 5140 126 200 650 1260 2000 3200 5000 197 312 489 630 1250 3125 312 498 794 1240 3125 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2R 1 1 1 1 2R 1 1 1 1 1 1 1 1 1 1 1 1 2R 2R 2R 1 1 1 2P 2R 1 1 1 1 1 1 1 1 1 1 1 1 -1 1 1 1 1 1 -1 1 1 1 1 1 1 1 1 1 1 15 x 7 19 x 9 26 x 12 26 x 12 30 x 15 37 x 15 15 x 7 19 x 8 19 x 9 26 x 12 30 x 15 37 x 15 44 x 18 14 x 6 19 x 8 25 x 9 26 x 12 30 x 15 37 x 15 46 x 20 14 x 6 19 x 8 19 x 8 26 x 12 26 x 12 39 x 16 19 x 8 19 x 8 25 x 10 26 x 12 37 x 15 17 22 29 29 32 42 17 22 22 29 32 42 49 17 22 29 29 42 42 49 17 22 22 29 29 42 22 22 29 29 42 Part Number S D __-0.63-400 S D __-0.63-500 S D __-0.63-630 S D __-0.63-1000 S D __-0.63-2000 S D __-0.63-2500 S D __-0.63-4000 IDC Amps 0.63 1.0 1.6 2.0 2.5 3.15 LO (µH) Electrical Specifications @ 25°C Test frequency: Inductance measured@ 10kHz / 10mV Test voltage between windings: 500Vrms Operating temperature: -40°C to +125°C Climatic category: IEC68-1 40/125/56 Coil Siz e O.D. x Ht.
