smt power inductors flat coils - pg0426nl series notes from tables 1. the temperature of the component (ambient plus temperature rise) must be within the standard operating temperature range. 2. the saturation current, i sat , is the current at which the component inductance drops by 30% (typical) at an ambient temperature of 25c. 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. 3. the heating current, i dc , is the dc current required to raise the component temperature by approximately 40c. 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. 4. core loss approximation is based on published core data: core loss = k1 * (f) 1.33 * (k2 i) 2.51 where: core loss = in watts k1 = 8.75e-9 f = switching frequency in khz k1 & k2 = core loss factors i = delta i across the component in ampere k2 i = one half of the peak to peak flux density across the component in gauss 5. unless otherwise specified, all testing is made at 100khz, 0.1v ac . 6. optional tape & reel packaging can be ordered by adding a " t " suffix to the part number (i.e. pg0426.101nl becomes pg0426.101nl t ). pulse complies to industry standard tape and reel specification eia481.
