The heating current is the DC current which causes the part temperature be connected in series or parallel to form a single inductor within a single to increase by approximately 40C. This current is determined by solder- phase application. ing the component on a typical application PCB, and then applying the current to the device for 30 minutes. 3.

Pulse complies with industry standard tape and reel specification EIA481. 5. The rated current as listed is either the saturation current or the heating current depending on which value is lower. 10. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. 6. The saturation current is the current which causes the inductance to drop a maximum of 26% from the nominal inductance at 0Adc at the stated 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 50 SPM2007 (7/09)smt POWer inductOrs Power Beads - PA0766NL Series mechanical Inches Weight ...........5.2 grams Dimensions: mm Tape & Reel ........ 250/reel .010 Unless otherwise specified, all tolerances are 0,25 schematics and Footprints 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 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 51 SPM2007 (7/09)
