SMT Power Inductors Power Beads - PA1320NL and PA1320ANL Series Current Rating: Over 75Apk Inductance Range: 120nH to 310nH Height: 6.5mm Max Footprint: 10.4mm x 8.0mm Max Electrical Specifications @ 25C - Operating Temperature -40C to +130C7 Part Number Inductance @ 0ADC (nH 20%) Inductance @ Irated (nH TYP) Irated1 (ADC) PA1320.121NL 120 120 PA1320.141NL 140 PA1320.171NL DCR2 (m) Saturation Current3 (A TYP) 25C 100C 40 90 73 140 40 76 64 180 174 40 0.48 8% (NL) 54.5 52 PA1320.221NL 200 185 40 0.47 5%(ANL) 55 45 PA1320.301NL 310 250 30 34 29.5 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 5. to point , as shown below on the mechanical drawing. The standard part PA1320. XXXNL has a DCR tolerance of +/-8%. A tighter DCR tolerance (+/-5%) part is available by changing the NL suffix to ANL (i.e. PA1320.121NL becomes PA1320.121ANL). 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 6. 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 7. by approximately 40C. This current is determined by soldering the component on a .315 [8.00] MAX 40 typical application PCB, and then applying the current to the device for 30 minutes with 25LFM of forced air cooling. In high volt*time applications, additional heating in the component can occur due to core losses in the inductor which may necessitate 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. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. PA1320.121NL becomes PA1320.121NLT). Pulse complies to industry standard tape and reel specification EIA481. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
