The rated current as listed is either the saturation current or the heating current depending 5. The temperature of the component (ambient plus temperature rise) must be within on which value is lower. the stated operating temperature range. 2. The saturation current is the typical current which causes the inductance to drop by 20% at 6. Add “T” suffix to the part number for Tape & Reel version (i.e. PA2050.582NLT). the stated ambient temperatures (25°C and 100°C). This current is determined by placing 7. This RoHS compliant series should be processed in accordance with JEDEC J-STD-020C the component in the specified ambient environment and applying a s hort duration reflow standard. pulse current (to eliminate self-heating effects) to the component. 3. The heating current is the DC current which causes the part temperature to increase by approximately 40°C. 4. In high volt*time applications, additional heating in the component can occur due to core losses in the inductor which may neccessitate derating the current in order to limit the temperature rise of the component. To determine the approximate total losses (or temperature rise) for a given application, the coreloss and temperature rise formula can be used: ΔB (Gauss) = K2 * ΔI Core Loss (W) = 1.5E-13 * (Freq_kHz) 1.63 * ΔB2.62 USA 215 781 6400 Germany 49 7032 7806 0 1 Singapore 65 6287 8998 pulseelectronics.com Shanghai 86 21 62787060 China 86 755 33966678 Taiwan 886 3 4356768 P661.D (03/14) PA2050.XXXNL Mechanical Schematics Inches Dimensions: PA2050.XXXNL DATE CODE CTRY OF MFG SMT POWER INDUCTORS Wire Wound mm Unless otherwise specified, all tolerances are ± .010 0,25 Inductance vs Current Characteristics pulseelectronics.com 2 P661.D (03/14) SMT POWER INDUCTORS Wire Wound Inductance vs Current Characteristics (continued) For More Information Pulse North America Headquarters Two Pearl Buck Court Bristol, PA 19007 U.S.A.
