The NR6045 Series is a magnetic-resin shielded SMD Power Inductor in a 6.3 mm × 6.3 mm footprint with a 4.5mm height. This taller profile, compared to the NR6028, allows for an exceptionally high saturation current (Isat) of up to 15.0A and an extremely wide inductance range from 0.47µH to 1500µH (1.5mH).
Its magnetic-resin shielded construction and closed magnetic circuit design ensure ultra-low acoustic noise and low EMI. The NR6045 is a robust smd power inductor, a highly reliable magnetic component solution for demanding applications like notebooks, servers, and automotive systems. The NR6045 is a top-tier choice for power inductor design.
Key Features

Notes:
Test Conditions: All test data is referenced to 25°C ambient.
Operating Temperature Range: -40°C to +125°C (ambient plus self-temperature rise).
Isat (Saturation Current): DC current (A) that will cause L₀ to drop approximately 30%.
Idc (Heating Current): DC current (A) that will cause an approximate ΔT of 40°C.
Temperature Limit: The part temperature (ambient + temp rise) should not exceed 125°C under worst-case operating conditions.
