Optional Tape & Reel packaging can be ordered by adding a T derating the current in order to limit the temperature rise of the component. In suffix to the part number (i.e P G0087.102NL becomes PG0087.102NLT). order to determine the approximate total loss (or temperature rise) for a given Pulse complies with industry standard Tape and Tape & Reel application, both copper losses and core losses should be taken into account. specification EIA481. 3. The NL suffix indicates an RoHS-compliant part numer. Non-NL Estimated Temperature Rise: suffixed parts are not necessarily RoHS compliant, but are electrically and mechanically equivalent to NL versions. If a part number does not .833 Trise = Total loss (mW) / K0 (C) have the NL version, but an RoHS compliant version is required, please contact Pulse for availability. Total Loss = Copper loss + Core loss (mW) 4. Temperature of the component (ambient plus temperature rise) must be 2 Copper loss = IRMS x DCR (Typical) (mW) within specified operating temperature range. 1/2 2 2 5. The rated current (Irated) as listed is either the saturation current or the Irms = IDC + I /12 (A) heating current depending on which value is lower. 2.38 1.23 Core loss = K1 x f (kHz) x Bac (Ga) (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 25C. Bac (peak to peak flux density) = K2 x I (Ga) This current is determined by placing the component in the specified ambient = K2/L (H) x Et (V-Sec) (Ga) environment and applying a short duration pulse current (to eliminate self- where f varies between 25kHz and 1MHz, and Bac is heating effects) to the component. less than 2500 Gauss. 7. The heating current, Idc, is the DC current required to raise the component K2 is a core size and winding dependent value and is temperature by the indicated delta (approximately). The heating current is given for each p/n in the proceeding datasheets.
