Notes: by 20% at 25°C. This current is determined by placing the component in the specified ambient environment and applying a short duration pulse 1. The temperature of the component (ambient plus temperature rise) must current (to eliminate self-heating effects) to the component. be within the stated operating temperature range. 2. The above transformers and inductors have been tested and approved 5. The heating current is the dc current which causes the temperature of the part to increase by approximately 40°C. by Pulse's power IC partners and are sited in the appropriate datasheet or evaluation board documentation at these companies. To determine 6. Add 'T' suffix to the part number for Tape & Reel version (ie: PB2041NLT). which IC and IC partners are matched with the above Pulse part numbers 7. The "NL" suffix indicates an RoHS-compliant part number. Non-NL please consult the IC Cross Reference on the Pulse website. suffixed parts are not necessarily RoHS compliant, but are electrically 3. The rated current as listed is either 85% of the saturation current or the and mechanically equivalent to NL versions. If a part number does not heating current whichever is lower. have the "NL" suffix, but an RoHS compliant version is required, please contact Pulse for availability. 4. The saturation current is the current which causes the inductance to drop Mechanicals EFD 15 .640 16,26 MAX Part Number Date Code Country of Origin 10-PIN SMT .675 17,15 MAX .960 24,38 .680 17,27 .850 21,59 MAX Part Number Date Code Country of Origin 10X .035 0,90 10X .028 0,71 .098 2,50 .098 2,50 .392 9,96 12X .392 9,96 .098 2,50 SUGGESTED PAD LAYOUT .330 MAX 8,38 .005/0,13 10 SURFACES .875 22,23 MAX .722 18,34 .900 22,86 10X .035 0,90 .098 2,50 .490 12,45 .490 12,45 SUGGESTED PAD LAYOUT .330 MAX 8,38 10X 0°- 8° .010 0,25 .028 0,71 12-PIN SMT .062 ± .006 10X 1,57 ± 0,15 .010 ± .002 0,25 ± 0,05 .004/0,10 12 SURFACES 12X .072 1,83 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 104 SPM2007 (11/07) HIGH FREQUENCY WIRE WOUND TRANSFORMERS EFD Platforms - EFD15, EFD20 and EFD25 Mechanicals EFD 20 .860 21,84 MAX Part Number Date Code Country of Origin 10X .039 1,00 .148 3,76 10-PIN SMT 12 1.030 26,16 MAX 12-PIN SMT .860 21,84 MAX .860 21,84 7 1.050 26,67 1.150 29,21 MAX Part Number Date Code Country of Origin 10X .080 2,03 .148 3,76 .592 15,21 12X .028 0,71 .118 3,00 .592 15,21 1 SUGGESTED PAD LAYOUT 12 7 1.190 30,23 .930 23,62 1 6 12X .060 1,52 .118 3,00 .590 14,99 6 .590 14,99 SUGGESTED PAD LAYOUT .410 MAX 10,41 .450 MAX 11,43 .010 ± .002 0,25 ± 0,05 .005/0,13 10X .039 1,00 10 SURFACES .010 ± .002 0,25 ± 0,05 .006 /0,15 12 SURFACES 12X .080 2,03 8-PIN THT .826 20,98 MAX .512 13,00 MAX Pin 8 Pin 1 Pin 4 Pin 4 8X Ø .826 20,98 MAX Part Number Date Code Country of Origin .591 ± .006 15,01 ± 0,15 .031 0,79 .197 5,00 .689 ± .006 17,50 ± 0,15 SUGGESTED PAD LAYOUT 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 105 SPM2007 (11/07) HIGH FREQUENCY WIRE WOUND TRANSFORMERS EFD Platforms - EFD15, EFD20 and EFD25 Mechanicals EFD 25 10-PIN SMT 1.030 26,16 MAX Part Number Date Code Country of Origin 10X .043 1,09 .197 5,00 1.040 26,42 MAX 1.140 28,96 1.260 32,00 MAX 12-PIN SMT 1.350 34,29 1.260 32,00 MAX Part Number Date Code Country of Origin 10X .074 1,88 .197 5,00 .788 20,00 12X .043 1,09 .158 4,01 .788 20,00 SUGGESTED PAD LAYOUT .530 MAX 13,46 1.140 28,96 12X .074 1,88 .158 4,01 .790 20,07 1.300 33,02 .790 20,07 SUGGESTED PAD LAYOUT .540 MAX 13,72 .010 ± .002 0,25 ± 0,05 .005/0,13 10X 10 SURFACES .035 0,89 12 SURFACES 12X .035 0,89 10-PIN THT 1.040 26,42 MAX 1.028 26,11 MAX .005/0,13 .012 ± .002 0,30 ± 0,05 .886 22,50 Part Number Date Code Country of Origin 10X Ø.045 1,14 .200 5,08 .800 20,32 Pin 1 Chamfer SUGGESTED PAD LAYOUT .550 MAX 13,97 1 1 5 .800 20,32 .200 5,08 .138 ± .012 3,50 ± 0,30 5 6 10X .028 0,71 5 .886 22,50 10 6 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 106 SPM2007 (11/07) HIGH FREQUENCY WIRE WOUND TRANSFORMERS EFD Platforms - EFD15, EFD20 and EFD25 Schematics EFD 15 PB2187 PA0476 1 9,8 36-75v 225kHz 2 +12v/1.7A 3 5 15v/0.1A +5v/3A 5 3.3v/3A 10 8 5 2 10v/0.015A 11 9 7 12 30-57v 100kHz 11 5.0v/2A 10 8 5 2 9 7.5v/0.01A 7 1 NOTE: Pins 8, 9 and 10 to be connected on customer PCB 1 3 10v/0.015A 5.6v/0.01A 1 PA1067 NOTE: Pins 9 to 8 and Pins 7 to 6 to be connected on customer PCB PA1039 12 28-59v 100kHz 7 8 9 Auxiliary 10v/.02A 6 3 10 11 12 Primary 18-72v 4 7,6 3 4 PA0691 1 NOTE: Pins 8, 9 and 10 to be connected on customer PCB RESET 2 3 12, 11,10 34-75v 3.3v/6A 9, 8, 7 4 5 AUX 12v/25mA 6 EFD 20 PB2003 PA1040 2 30-57v 250kHz 1,2 9 1 6 7 3 2 3.3v/4.5A 9,8,7 15v/0.1A 36-75v 4 +12v/4.5A 3,4 5 10,11,12 Pri.
