Pulse Jack SMT Power Inductors Power Beads - PA2891.XXXHL Series Electronics Current Rating: Over 72 Apk Inductance Range: 210nH to 440nH Height: 8.0 mm Max Footprint: 13.7mm x 12.95mm Max Halogen Free Electrical Specifications @ 25°C — Operating Temperature -40°C to +130°C 7 Part Number Inductance1 @ 0ADC (nH +/- 10%) Inductance2 @Irated (nH TYP) Irated (ADC) PA2891.211HL PA2891.261HL PA2891.321HL PA2891.441HL 210 260 320 440 210 260 315 440 71 56 45 30 3 4 DCR (mΩ nominal) 0.22 +/- 10% NOTES: 1. Inductance measured at 100kHz, 100mVrms. 2. Inductance at Irated is the value of the inductance at 25°C at the listed rated current. 3. The rated current as listed is either the saturation current (25°C or 100°C) or the heating current depending on which value is lower. 4. The nominal DCR is measured from point a to point b , as shown below on the mechanical drawing. 5. The saturation current is the typical current which causes the inductance to drop by 20% at the stated ambient temperatures (25°C, 100°C and 125°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.

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. 8. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (i.e. PA2891.211HL becomes PA2891.211HLT). Pulse complies to industry standard tape and reel specification EIA481. The tape and reel for this product has a width (W=24mm), pitch (Po=16.0mm) and depth (Ko=9.8mm). 9. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. 6. The heating current is the DC current which causes the part temperature to increase by approximately 40°C when used in a typical application.
