The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. 2. The rated current is the current that will cause the temperature of the part to increase by 40°C with 3.6 volt * µsec across the component and 100LFM of forced air cooling. 3. To determine the inductance of a component at a different operating current, use the graph below for the appropriate material type. 4. In high volt-µsec applications additional heating may occur due to core losses in the inductor which may necessitate derating the current in order to limit the temperature rise of the component. In order to determine the approximate total losses (or temperature rise) of the component in particular applications, the following formulas can be used. Estimated Temperature Rise: Trise = AirFlowFactor * K5 * (Coreloss(W) + Copperloss(W)).833 (C) Where AirFlowFactor = 1 (no air flow), 0.53 (100LFM), 0.39 (200LFM), 0.35 (300LFM), 0.30 (400LFM) CopperLoss = Irms2 * DCR_Typical (mW) / 1000 DCR_Typical (mW) = .85 * DCR_Max(from table) CoreLoss = K2 * (Freq_kHz)K3 * (DB/2000)K4 DB = K1 * Volt-µsec Mechanical Dimensions (in/mm) A B C B C .374 .748 9,50 19,00 .413 .748 10,50 19,00 .345 .545 8,80 13,80 .400 .660 10,20 16,80 .345 .545 8,80 13,80 .374 N/A 9,50 .492 .906 12,50 23,00 .276 .571 7,00 14,50 .323 .556 8,20 14,10 .374 .630 9,50 16,00 .325 N/A 8,30 .374 N/A 9,50 .440 .980 11,20 24,90 D E D E .126 .098 3,20 2,50 .126 .106 3,20 2,68 .129 .052 3,30 1,30 .150 .050 3,80 1,30 .129 .052 3,30 1,30 .250 N/A 6,40 .130 .055 3,30 1,40 .126 .041 3,20 1,05 .157 .048 4,00 1,20 .140 .063 3,60 1,60 .130 .045 3,30 1,10 .250 .054 6,40 1,40 .250 .054 6,40 1,40 F F .354 9,00 .354 9,00 .300 7,60 .300 7,60 .300 7,60 .245 6,20 .300 7,60 .276 7,00 .250 6,40 .295 7,50 .300 7,60 .240 6,10 .310 7,90 � ��� � ��� � ��� � ��� Schematic � Dimensions: Inches mm � ���������������������������� Part No. Part No. A .807 PG0122 20,50 PG0123 .807w 20,50 .625 PA0690 15,90 PA0235L N/A .625 PA0689 15,90 .874 PA0430L 22,20 .906 P1967L 23,00 .571 PG0116 14,50 .604 PA0489L 15,30 .630 PG0112 16,00 .610 P1715L 15,50 .874 PA0431L 22,20 .980 PA0432L 24,90 � ��� � ��� ������������������������������� ��� ��� �������������������� �� ������������������ �� �� ������������������ �� � � �� �� �� �� �� �� �� �� �� ��� ��� ��� ���������������������������� 2 pulseelectronics.com SPM2007 (06/11)
