The rated current as listed is either the saturation current or the heating current depending on which value is lower. 2. 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 (25°C and 100°C). Inductance at Isat is the minimum inductance when measured at Isat (25°C and 100°C).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 40°C. This current is determined by solder- Inductance @Isat (nH TYP) Inductance @Isat (nH MIN) 96 78 Saturation Current 3 (A TYP) 25°C 100°C Part Number PA2202.XXXNL D/C MFG. 75 36 ing the component on a typical application PCB, and then applying the current to the device for 30 minutes. 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. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. PA2202.121NL becomes PA2202.121NLT). 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.
