The temperature of the component (ambient plus temperature rise) muse be within 6. Core Loss approximation is based on published core data: 1.035 2.263 thestandard operating temperature range. Core Loss = K1*(f) *(K2I) 2. Inductance at Irated is a typical inductance value for the component taken at rated Where: Core Loss = in Watts current. f = switching frequency in kHz 3. The rated current listed is the lower of the saturation current 25C or the heating K1 & K2 = core loss factors current. I = delta I across the component in Ampere 4. The saturation current, ISAT, is the current at which the component inductance drops K2I = one half of the peak to peak flux density by 20%(typical) at an ambient temperature of 25C. This current is determined by across the component in Gauss placing the component in the specified ambient environment and applying a short 7. Unless otherwise specified, all testing is made at 100kHz, 0.1V AC. duration pulse current (to eliminate self-heating effects) to the component. 8. Optional Tape & Reel packaging can be ordered by adding a T suffix to the part 5. The heating current, IDC, is the DC current required to raise the component tempera- number (i.e. PG0077.401NL becomes PG0077.401NLT). Pulse complies to industry ture by approximately 40C. The heating current is determined by mounting the standard tape and reel specification EIA481. component on a typical PCB and applying current for 30 minutes. The temperature is measured by placing the thermocouple on top of the unit under test. Take note that * Contact Pulse for availability the components performance varies depending on the system condition. It is sug- gested that the component be tested at the system level, to verify the temperature rise of the component during system operation. 1 power.pulseelectronics.com SPM2007 37 (02/19) SMT Power Inductors Flat Coils - PG0077NL and PG0084NL Series Mechanical Schematic PG0077.XXX, PG0084.XXX PG0077 PG0084 Weight ..............5.5 grams ...........3.5 grams Tape & Reel .......300/reel .............400/reel .Inches Dimensions: mm Unless otherwise specified, ..010 all tolerances are: 0,25 Max.
