The temperature of the component (ambient plus temperature rise) must be within the specified operating temperature range. 2. Inductance at Irated is a typical inductance value for the compo- nent taken at rated current. 3. The rated current listed is the lower of the saturation current @ 25°C or the heating current. 4. The saturation current, ISAT, is the current at which the compo- nent inductance drops by 20% (typical) at an ambient tempera- ture of 25°C. This current is determined by placing the compo- nent in the specified ambient environment and applying a short duration pulse current (to eliminate self-heating effects) to the component. 5. The heating current, IDC, is the DC current required to raise the component temperature by approximately 40°C. The heating cur- rent is determined by mounting the component on a typical PCB and applying current for 30 minutes. The temperature is mea- sured 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. 6. Core loss approximation is based on published core data: Core Loss = K1 * (f)1.30 * (K2 ΔI)2.41 Where: Core Loss = in Watts K1= 3.50E-10 f = switching frequency in kHz K1 & K2 = core loss factors ΔΔI = delta I across the component in Ampere K2 ΔΔI = one half of the peak to peak flux density across the component in Gauss 7. Unless otherwise specified, all testing is made at 100kHz, 0.1VAC. 8. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. PG0277.401NL becomes PG0277.401NLT). Pulse complies to industry standard tape and reel specification EIA481.
