Non-NL suffixed parts are not necessarily RoHS compliant, but are electrically and mechanically equivalent to NL versions. If a part number does not have the “NL” suffix, but an RoHS compliant version is required, please contact Pulse for availability. 1 pulseelectronics.com SPM2007 (06/11)

THT Power Inductors Toroid - Bare Coil Series Notes from Tables 1. The temperature of the component (ambient plus temperature rise) must be within the stated Estimated Temperature Rise: operating temperature range. Trise = AirFlowFactor * K5 * (Coreloss(W) + Copperloss(W)).833 (C) 2. The rated current is the current that will cause the temperature Where of the part to increase by 40°C with 3.6 volt * µsec across the AirFlowFactor = 1 (no air flow), 0.53 (100LFM), 0.39 (200LFM), 0.35 (300LFM), 0.30 (400LFM) component and 100LFM of forced air cooling. CopperLoss = Irms2 * DCR_Typical (mΩ) / 1000 3. To determine the inductance of a component at a different operating current, use the graph below for the appropriate material type. DCR_Typical (mW) = .85 * DCR_Max(from table) 4. In high volt-µsec applications additional heating may occur due to core losses in the inductor CoreLoss = K2 * (Freq_kHz)K3 * (DB/2000)K4 which may necessitate derating the DB = K1 * Volt-µsec current in order to limit the temperature rise of the component. In order to determine the approximate total losses (or temperature rise) of the component in particular applications, the following formulas can be used.
