Core loss approximation is based on published core data: Core Loss = K1 * (f) * (K2ΔI) 1. The temperature of the component (ambient plus temperature rise) must be within Where: Core Loss = in Watts the specified operating temperature range. f = switching frequency in kHz 2. The saturation current, ISAT, is the current at which the component inductance drops K1 & K2 = core loss factors by 30% (typical) at an ambient temperature of 25°C. This current is determined by ΔI = delta I across the component in Ampere placing the component in the specified ambient environment and applying a short K2ΔI = one half of the peak to peak flux density duration pulse current (to eliminate self-heating effects) to the component. across the component in Gauss 3. The heating current, IDC, is the DC current required to raise the component temperature 5. Unless otherwise specified, all testing is made at 100kHz, 0.1VAC. by approximately 40°C. The heating current is determined by mounting the component 6. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part on a typical PCB and applying current for 30 minutes. The temperature is measured number (i.e. PG0426.101NL becomes PG0426.101NLT). Pulse complies to industry by placing the thermocouple on top of the unit under test. Take note that the standard tape and reel specification EIA481. 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.
