The temperature of the component (ambient plus temperature component be tested at the system level, to verify the tempera- rise) must be within the specified operating temperature range. ture rise of the component during system operation. 2. Inductance at Irated is a typical inductance value for the 6. Core loss approximation is based on published core data: component taken at rated current. 1.33 2.51 Core Loss = K1 * (f) * (K2I) 3. The rated current listed is the lower of the saturation current Where: Core Loss = in Watts 25C or the heating current. 4. The saturation current, ISAT, is the current at which the K1= 1.05E-10 component inductance drops by 20% (typical) at an ambient f = switching frequency in kHz temperature of 25C. This current is determined by placing the K1 & K2 = core loss factors component in the specified ambient environment and applying a I = delta I across the component in Ampere short duration pulse current (to eliminate self-heating effects) to the component. K2I = one half of the peak to peak flux density 5. The heating current, IDC, is the DC current required to raise the across the component in Gauss 7. Unless otherwise specified, all testing is made at component temperature by approximately 40C. The heating 100kHz, 0.1VAC. current is determined by mounting the component on a typical PCB and applying current for 30 minutes. The temperature is 8. Optional Tape & Reel packaging can be ordered by adding a measured by placing the thermocouple on top of the unit under suffix to the part number (i.e. PG0434.401NL becomes test. Take note that the components performance varies PG0434.401NLT). Pulse complies to industry standard tape and depending on the system condition. It is suggested that the reel specification EIA481.
