The NRS prefix denotes the NR series S-type (semi-shielded) power inductor family, 6028 indicates the 6.0 x 2.8mm form factor, T denotes tape packaging, 4R7 indicates 4.7uH inductance, MM denotes +\/-20% tolerance, G indicates halogen-free, and K denotes embossed tape packaging (2000 pcs\/reel). The semi-shielded construction uses a magnetic resin coating over the ferrite drum core, providing significant EMI reduction compared to unshielded types while maintaining a lower profile than fully shielded variants. The inductor features a low DCR of 31mOhm typical (40.3mOhm max) for minimal power loss, a rated current of 3A based on a 40C temperature rise, and a saturation current of 2.7A at -30% inductance drop. The ferrite core material provides stable inductance characteristics up to the 39MHz self-resonant frequency.","working_principle":"The NRS6028T4R7MMGK operates as an energy storage element in switching power supplies: (1) Energy Storage: During the ON phase of a buck converter, current flows through the inductor and energy is stored in the magnetic field of the ferrite core (E = 0.5 * L * I^2). The inductance of 4.7uH determines the rate of current change (V = L * dI\/dt). (2) Current Smoothing: During the OFF phase, the stored magnetic energy maintains current flow to the load through the freewheeling diode or synchronous MOSFET, smoothing the pulsating switch current into a continuous DC output. (3) Saturation Behavior: As DC current increases beyond 2.7A (Isat), the ferrite core begins to saturate, reducing effective inductance by 30%. Beyond saturation, inductance drops sharply and the inductor can no longer effectively store energy or limit ripple current. (4) Semi-Shielding: The magnetic resin coating around the drum core contains a significant portion of the magnetic flux leakage that would otherwise radiate from an unshielded inductor, reducing EMI coupling to nearby circuits while maintaining lower cost and profile than fully shielded types.","pin_description":"
