The rated current as listed is either the saturation current or the heating current depending on which value is lower. 2. The saturation current is the current which causes the inductance to drop by 10% at the stated ambient temperatures (-40°C, 25°C, 125°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. 3. The heating current is the DC current which causes the temperature of the part to increase by approximately 40°C. This current is determined by mounting the component on a PCB with .25" wide, 2 oz. equivalent copper traces, and applying the current to the device for 30 minutes. In the series hookup mode, the resistance of the interconnection needs to be taken into account when calculating temperature rise. 4. In high volt*time applications additional heating in the component can occur due to core losses in the inductor which may neccessitate derating the current in order to limit the temperature rise of the component. In order to determine the approximate total losses (or temperature rise) for a given application, both copper losses and core losses should be taken into account. 5. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number, (i.e. PA0135.102T). 6. To order RoHS compliant part, add the suffix “NL” to the part number (i.e. PA0135.102 becomes PA0135.102NL and PA0135.102T becomes PA0135.102NLT). Estimated Temperature Rise: .833 Trise = Coreloss (mW) + DCRloss (mW) (°C) K0 Coreloss = K1 * ( Fsw(kHz)) 1.6688 * (K2 * dI)2.17 (mW) DCRloss = Irms2 * DCR(mΩ) (mW) ½ IDC 2 + dI 2 (Arms) 12 Fsw(kHz) = switching frequency (kHz) Irms = dI = delta I across the component (A) The temperature of the component (ambient temperature + temperature rise) should be within the listed operating temperature range.
