The NR5020 Series is a low-profile, magnetic-resin shielded SMD Power Inductor. It features a 5.2 mm × 5.2 mm footprint and a slim 2.0mm maximum height, offering a high current rating in a thin package.
This NR5020 series is engineered to deliver a high saturation current (Isat) of up to 9.00A and an exceptionally wide inductance range, from 0.22µH all the way to 1200µH (1.2mH). Its unique magnetic-resin shielded construction and closed magnetic circuit design ensure ultra-low acoustic noise and low EMI. The low power inductor design makes the NR5020 a powerful, yet energy-saving, solution. Users rely on the clear inductor specifications of this SMD Power Inductor for highly stable performance.
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.
