Actual temperature of the component during system operation(ambient plus 7. Core loss approximation is based on published core data: 1.324 2.422 temperature rise) must be within the standard operating range. Core Loss = K1 * (f) * (B) in mW 2. Inductance at Irated is a typical inductance value for the component taken at rated K1 = 71.56 E-4 current. B = K2 * Vusec in mT 3. The rated current as listed is either the saturation current ( 25C) or the heating current f = switching frequency in MHz depending on which value is lower. K1 & K2 = core loss factors 4. The DCR of the part is measured at an ambient temperature of 20C3C from point a V = Voltage across the component in V and b as shown below on the mechanical drawing. Vusec = V * D /f 5. The saturation current, Isat, is the current at which the component inductance drop by D = Duty cycle 20% (typical) at an ambient temperature of 25C. This current is determined by placing 8. Unless otherwise specified, all testing is made at 100kHz, 0.1Vac the component in the specified ambient environment and applying a short duration 9. Optional Tape & Reel packaging can be ordered by adding a T suffix to the part pulse current (to eliminate self-heating effect) to the component. number (i.e. PG0871.222NL becomes PG0871.222NLT). Pulse complies to industry 6. The heating current, Idc, is the DC current required to raise the component temperature standard tape and reel specification EIA481. The tape and reel for this product has a by approximately 40C. The heating current is determined by mounting the component width(W=16.0mm), pitch(Po=12.0mm) and depth (Ko=6.8 mm). on a typical pcb and applying current for 30 minutes. The temperature is measured 10. The core is a conductive material so care should be taken when mounting this by placing the thermocouple on top of the unit under test. Take note that the component over an exposed via or if the voltage across the terminals exceeds components performance varies depending on the system condition. IT is suggested 24V. Trickle current through the core material may generate additional losses and that the component be tested at the system level, to verify the temperature rise of the potential overheating.
