The NR6028 Series is a low-profile, magnetic-resin shielded SMD Power Inductor in a 6.3 mm × 6.3 mm footprint and a slim 3.0mm maximum height, offering a step-up in performance from 5mm inductors while maintaining a low profile.
This series is engineered to provide an excellent saturation current (Isat) up to 6.90A and an exceptionally wide inductance range, from 0.68µH up to 1000µH (1mH). Its magnetic-resin shielded construction and closed magnetic circuit design ensure ultra-low acoustic noise and low EMI. The NR6028 is a magnetic component, and a power-saving and highly reliable solution for noise-sensitive, high-density power circuits. It features a robust ferrite inductor core and is ideal for Notebooks and Automotive Systems.

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.
