High current power inductors www.eaton.com/elx Product specifications Part number Part number (Tape and reel) OCL1 (μH) ±20% lrms 2 amps lsat 3 amps DCR (Ω)4 maximum @ 20°C Volt-μsec5 (V-μs) 1. Open Circuit Inductance Test Parameters: 300kHz, 0.250 Vrms, 0.0 Adc 2. DC current for an approximate temperature change of 40°C without core loss. Derating is necessary for AC currents. PCB layout, trace thickness and width, air-flow and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed 125°C under worst case operating conditions verified in the end application. 3. Peak current for approximately 30% rolloff. 4. Values @ 20°C 5. Applied Volt-Time product (V-μs) across the inductor. This value represents the applied V-μs at 300KHz neccessary to generate a core loss equal to 10% of the total losses for 40°C temperature rise.
