The rated current as listed is either the saturation current or the heating current depending 5. In high volt*time applications, additional heating in the component can occur due to on which value is lower. core losses in the inductor which may necessitate derating the current in order to limit 2. The nominal DCR tolerance is by design. The nominal DCR is measured from point a to the temperature rise of the component. To determine the approximate total losses (or point b , as shown below on the mechanical drawing. The standard part PA1320.XXXNL temperature rise) for a given application, the coreloss and temperature rise curves has a DCR tolerance of +/-8%. A tighter DCR tolerance (+/-5%) part is available by changing can be used. the NL suffix to ANL (i.e. PA1320.121NL becomes PA1320.121ANL). 6. Optional Tape & Reel packaging can be ordered by adding a T suffix to the part 3. The saturation current is the typical current which causes the inductance to drop by 20% at number (i.e. PA1320.121NL becomes PA1320.121NLT). Pulse complies to industry standard the stated ambient temperatures (25C and 100C). This current is determined by placing the tape and reel specification EIA481. component in the specified ambient environment and applying a short duration pulse 7. The temperature of the component (ambient plus temperature rise) must be within the current (to eliminate self-heating effects) to the component. stated operating temperature range. 4. The heating current is the DC current which causes the part temperature to increase by approximately 40C. This current is determined by soldering the component on a typical application PCB, and then applying the current to the device for 30 minutes with 25LFM of forced air cooling.
