Actual temperature of the component during system operation (ambient plus temperature rise) must be within the standard operating range. 2. Inductance at Irated is a typical inductance value for the component taken at rated current. 3. The rated current as listed is either the saturation current (@ 25°C) or the heating current depending on which value is lower. 4. The DCR of the part is measured at an ambient temperature of 20°C±3°C from point a to b as shown below on the mechanical drawing. 5. The saturation current, Isat, is the current at which the component inductance drop by 20% (typical) at an ambient temperature. This current is determined by placing the component in the specified ambient environment and applying a short duration pulse current (to eliminate self-heating effect) to the component. 6. The heating current, Idc, is the DC current required to raise the component temperature by 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 components’ 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. 0.098 [2.50] BOTTOM VIEW A 0.054 [1.40] BOTTOM VIEW B 1 SIZE X 1 2 3 2 3 (.094[2.40]) (.098[2.50]) 2 BOTTOM VIEW B .571[14.50] .197[5.00] HEIGHT MAX.

Core loss approximation is based on published core data (at 100°C): Core Loss = K1 * (f) 1.378 * (K2*ΔI) 2.864 in mW K1 = 1.01E-9 f = switching frequency in KHz K1 & K2 = core loss factors ΔI= delta I across the component in Ampere K2*ΔI=one half of the peak to peak flux density across the component in Gauss 8. Unless otherwise specified, all testing is made at 100kHz, 0.1Vac 9. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (i.e. PG1083.682NL becomes PG1083.682NLT). Pulse complies with industry standard tape and reel specification EIA481. The tape and reel for this product has a width (W=44.0mm), pitch (Po=32.0mm). The depth (Ko) has two types: 1) 10.6 mm for parts with height of 10.6mm max, 120 pieces/reel; 2) 12.9mm for the parts of 12.5mm max, 100 pieces/reel.
