SMT Power Inductors Power Beads - PA4059.XXXHLT Series POWER PRODUCTS Current Rating: Over 48Apk Inductance Range: 55nH Height: 4.6mm Max Footprint: 5.5mm x 5.7mm Max Halogen Free Electrical Specifications 25C - Operating Temperature -40C to +125C 4 Saturation Current 2 3 1 5 (A TYP) Part Inductance Inductance Irated DCR Heating Current Number 0ADC Irated (ADC) (m nominal) (A TYP) (nH +/- 20%) (nH TYP) 25C 100C PA4059.550HLT 55 55 35 0.20 +/- 10% 61 48 35 Notes: 1. Inductance is measured at 100kHz, 100mVrms. 2. The rated current as listed is either the saturation current or the heating current 6. In high volt*time applications, additional heating in the component can occure due to depending on which value is lower. core losses in the inductor which may necessitate derating the current in order to limit 3. The nominal DCR is measured from point a to b , as shown below on the the temperature rise of the component. To determine the approximate total losses (or mechanical drawing. temperature rise) for a given application, the coreloss and temperature rise curves can 4. The saturation current is the typical current which causes the inductance to drop be used. by 20% at the stated ambient temperatures (25C, 100C). This current is determined 7. The T suffix indicates the part is shipped in tape and reel packaging. Pulse complies to by placing the component in the specified ambient environment and applying a the industry standard type and reel specification EIA481. The tape and reel for this product short duration pulse current (to eliminate self-heating effects) to the component. has a width (W=16mm), pitch (Po=12mm) and depth (Ko=4.6mm). 5. The heating current is the DC current which causes the part temperature to increase 8. The temperature of the component (ambient plus temperature rise) must be within the by approximately 40C when used in a typical application. stated operating temperature range.
