The NR4030 Series is a robust SMD Power Inductor from the magnetic-resin shielded line. It features a compact 4.2 mm × 4.2 mm footprint and a 3.0mm maximum height, offering an excellent balance of size and wide value range.
This wide range inductor is engineered to provide a saturation current (Isat) up to 8.00A and an exceptionally wide inductance range, from 0.24µH up to 470µH. The construction utilizes a ferrite inductor core with a closed magnetic circuit and magnetic-resin shielding. This ensures ultra-low acoustic "buzz" noise and low EMI, critical for modern electronics. The NR4030 is a highly capable smd magnetic inductor for systems requiring reliable power filtering.

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.
