Core loss approximation is based on published core data: 1. The temperature of the component (ambient plus temperature rise) must be within 1.48 1.97 Core Loss = K1 * (f) * (K2ΔI) the specified operating temperature range. Where: Core Loss = in Watts 2. Inductance at Irated is a typical inductance value for the component taken at rated current. f = switching frequency in kHz 3. The rated current listed is the lower of the saturation current @ 25°C or the heating current. K1 & K2 = core loss factors 4. The inductance at Bias is the controlled inductance value measured after subjecting ΔI = delta I across the component in Ampere the part to the listed dc bias current. K2ΔI = one half of the peak to peak flux density 5. The saturation current, ISAT, is the current at which the component inductance drops across the component in Gauss by 20% (typical) at an ambient temperature of 25°C. This current is determined by 8. Unless otherwise specified, all testing is made at 100kHz, 0.1VAC. placing the component in the specified ambient environment and applying a short 9. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part duration pulse current (to eliminate self-heating effects) to the component. number (i.e. PG0255.601NL becomes PG0255.601NLT). Pulse complies to industry 6. The heating current, IDC, is the DC current required to raise the component temperature by standard tape and reel specification EIA481. approximately 40°C. The heating current is determined by mounting the 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 the component’s performance varies depending on the system condition. It is suggested that the component be tested at the system level, to verify the temperature rise of the component during system operation.
