The NR3015 Series is a low-profile, SMD Power Inductor from the magnetic-resin shielded line. It is engineered for high-density, ultra-thin applications, featuring a compact 3.2 mm × 3.2 mm footprint and an ultra-low 1.5mm maximum height.
This series uses a magnetic-resin shielded construction and a closed magnetic circuit to ensure ultra-low acoustic "buzz" noise and low EMI-critical features for modern mobile devices. It offers a 30% higher current rating than conventional inductors of the same size and provides a wide inductance range up to 150µH. This robust low profile inductor is a power-saving solution ideal for noise-sensitive portable electronics.

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.
