| SMT POWER INDUCTORS Power Beads - PA1320NL Series Current Rating: Over 75Apk Inductance Range: 120nH to 300nH Height: 6.5mm Max Footprint: 10.4mm x 8.0mm Max Electrical Specifications @ 25C -- Operating Temperature -40C to +130C 7 Part Number PA1320.121NL PA1320.171NL PA1320.221NL PA1320.301NL Inductance @0ADC (nH 20%) 120 172 215 310 Inductance @Irated (nH TYP) 120 160 200 230 Irated 1 (ADC) 40 40 40 31 0.48 8% DCR 2 (m) Saturation Current 3 (A TYP) 25C 77 58 43 31 100C 65 51 39 27 40 Heating 4 Current (A TYP) NOTES: 1. The rated current as listed is either the saturation current or the heating current depending on which value is lower. 2. The nominal DCR tolerance is by design. The nominal DCR is measured from point a to point b , as shown below on the mechanical drawing. 3. The saturation current is the typical current which causes the inductance to drop by 20% at the stated ambient temperatures (25C and 100C). This current is determined by placing the component in the specified ambient environment and applying a short duration pulse current (to eliminate self-heating effects) to the component. 4. The heating current is the DC current which causes the part temperature to increase by approximately 40C. This current is determined by solder- ing the component on a typical application PCB, and then applying the current to the device for 30 minutes with 25LFM of forced air cooling. 5. 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 curves can be used. 6. Pulse complies to industry standard tape and reel specification EIA481. 7. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
