The temperature of the component (ambient plus temperature rise) must 6. Core loss approximation is based on published core data: be within the standard operating temperature range. 1.035 2.263 Core Loss = K1 * (f) * (K2I) 2. Inductance at Irated is a typical inductance value for the component taken Where: Core Loss = in Watts at rated current. f = switching frequency in kHz 3. The rated current listed is the lower of the saturation current 25C or the heating current. K1 & K2 = core loss factors I = delta I across the component in Ampere 4. The saturation current, ISAT, is the current at which the component inductance drops by 20% (typical) at an ambient temperature of 25C. K2I = one half of the peak to peak flux density This current is determined by placing the component in the specified across the component in Gauss ambient environment and applying a short duration pulse current (to 7. Unless otherwise specified, all testing is made at 100kHz, 0.1VAC. eliminate self-heating effects) to the component. 8. Optional Tape & Reel packaging can be ordered by adding a suffix to 5. The heating current, IDC, is the DC current required to raise the the part number (i.e. PG0077.401NL becomes PG0077.401NLT). Pulse component temperature by approximately 40C. The heating current is complies to industry standard tape and reel specification EIA481. determined by mounting the component on a typical PCB and applying 9. TheN suffix indicates an RoHS-compliant part number. Non-NL suffixed current for 30 minutes. The temperature is measured by placing the ther- parts are not necessarily RoHS compliant, but are electrically and mocouple on top of the unit under test. Take note that the components mechanically equivalent to NL versions. If a part number does not have the performance varies depending on the system condition. It is suggested N suffix, but an RoHS compliant version is required, please contact that the component be tested at the system level, to verify the Pulse for availability. temperature rise of the component during system operation.
