Actual temperature of the component during system operation (ambient plus rise of the component during system operation. temperature rise) must be within the standard operating range. 7. Core loss approximation is based on published core data: 2. Inductance at Irated is a typical inductance value for the component taken at rated Core Loss = K1 * (f)1.72 * (K2I)2.41in mW current. K1 = 8.68E - 10 3. The rated current listed is either the saturation current ( 25C) or the heating cur- f = switching frequency in KHz rent depending on which value is lower. K1 & K2 = core loss factors 4. The DCR of the part is measured at an ambient temperature of 20C 3C from I = delta I across the component in Ampere point a to b as shown below on the mechanical drawing. K2I = one half of the peak to peak flux density across the component in Gauss 5. The saturation current, Isat, is the current at which the component inductance drop 8. Unless otherwise specified, all testing is made at 100KHz, 0.1Vac by 20% (typical) at an ambient temperature. This current is determined by placing 9. Optional Tape and Reel packaging can be ordered by adding a T suffix to the part the component in the specified ambient environment and applying a short duration number (i.e. PG0926.223NL becomes PG0926.223NLT). Pulse complies with industry pulse current (to eliminate self-heating effect) to the component. standard tape and reel specification EIA481. The tape and reel for this product has a 6. The heating current, Idc, is the DC current required to raise the component tempera- width (W=32.0mm), pitch (Po=20.0mm) and depth (Ko=8.35mm). ture by approximately 40C. The heating current is determined by mounting the 10. The core is a conductive material so care should be taken when mounting this com- component on a typical PCB and applying current for 30 minutes.
