In high volt*time (Et) or ripple current applications, additional heating in the component can occur due to core losses in the inductor which may necessitate derating the current in order to limit the temperature rise of the component. In order to determine the approximate total loss (or temperature rise) for a given application, both copper losses and core losses should be taken into account. 1. Unless otherwise specified, all testing is made at 100kHz, 0.1VAC. 2. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. P1166.102 becomes P1166.102T). Pulse complies with industry standard Tape and Tape & Reel specification EIA481. 3. To order RoHS compliant part, add the suffix "NL" to the part number (i.e. P1166.102 becomes P1166.102NL and P1166.102T becomes P1166.102NLT). Estimated Temperature Rise: 4. Temperature of the component (ambient plus temperature rise) must be within specified operating temperature range. Trise = [Total loss (mW) / K0].833 (oC ) Total loss = Copper loss + Core loss (mW) 5. The rated current (Irated) as listed is either the saturation current or the heating current depending on which value is lower. Copper loss = IRMS2 x DCR (Typical) (mW) 6. The saturation current, Isat, is the current at which the component inductance drops by the indicated percentage (typical) at an ambient temperature of 25°C. This current is determined by placing the component in the specified ambient environment and applying a short duration pulse current (to eliminate self-heating effects) to the component. Irms = [IDC2 + ΔI2/12]1/2 (A) Core loss = K1 x f (kHz)1.23 x Bac(Ga)2.38 (mW) Bac (peak to peak flux density) = K2 x ΔI (Ga) [= K2/L(µH) x Et(V-µSec) (Ga)] where f varies between 25kHz and 1MHz, and Bac is less than 2500 Gauss. K2 is a core size and winding dependant value and is given for each p/n in the proceeding datasheets. K0 & K1 are platform and material dependant constants and are given in the table below for each platform.

The heating current, Idc, is the DC current required to raise the component temperature by the indicated delta (approximately). 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.

It is suggested that the component be tested at the system level, to verify the temperature rise of the component during system operation.
