The NR5040 Series is a magnetic-resin shielded SMD Power Inductor in a 5.2 mm × 5.2 mm footprint. It is distinguished by its 4.1mm maximum height, a profile that allows for an exceptionally wide inductance range, from 1.0µH up to 1500µH (1.5mH).
This NR5040 series is engineered to provide high saturation current (Isat) up to 7.35A while offering high inductance values in a compact package. Its unique magnetic-resin shielded construction and closed magnetic circuit design ensure ultra-low acoustic noise and low EMI. As one of the core inductor components, the NR5040 is a highly capable, power-saving solution for applications ranging from mobile devices to notebooks and servers.

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.
