Actual temperature of the component during system operation (ambient plus temperature rise) must be 7. Core loss approximation is based on published core data (at 100C): 1.378 2.864 within the standard operating range. Core Loss = K1 * (f) * (K2*I) in mW 2. Inductance at Irated is a typical inductance value for the component taken at rated current. K1 = 1.01E-9 3. The rated current as listed is either the saturation current ( 25C) or the heating current depending on f = switching frequency in KHz which value is lower. K1 & K2 = core loss factors 4. The DCR of the part is measured at an ambient temperature of 20C3C from point a to b as shown below I= delta I across the component in Ampere on the mechanical drawing. K2*I=one half of the peak to peak flux density across the component in Gauss 5. The saturation current, Isat, is the current at which the component inductance drop by 20% (typical) at an 8. Unless otherwise specified, all testing is made at 100kHz, 0.1Vac ambient temperature. This current is determined by placing the component in the specified ambient envi- 9. Optional Tape & Reel packaging can be ordered by adding a T suffix to the part number (i.e. PG1083.682NL ronment and applying a short duration pulse current (to eliminate self-heating effect) to the component. becomes PG1083.682NLT). Pulse complies with industry standard tape and reel specification EIA481. The 6. The heating current, Idc, is the DC current required to raise the component temperature by approximately tape and reel for this product has a width (W=44.0mm), pitch (Po=32.0mm). The depth (Ko) has two types: 40C. The heating current is determined by mounting the component on a typical PCB and applying current 1) 10.6 mm for parts with height of 10.6mm max, 120 pieces/reel 2) 12.9mm for the parts of 12.5mm max, for 30 minutes. The temperature is measured by placing the thermocouple on top of the unit under test. 100 pieces/reel. Take note that the components performance varies depending on the system condition.
