Its 330 nH inductance and 4.8 A continuous current rating target DC-DC converter output filters and power-supply rails where the inductor sees the full load current without saturating. The 6.8 A saturation current (Isat) gives headroom above the 4.8 A rated current — the core does not roll off inductance until well past the continuous operating point, which matters for transient response in a buck converter stepping from light load to full load. ## DC resistance and thermal budget Maximum DCR is 21 mOhm — at 4.8 A the I²R loss is roughly 0.48 W, which this 1008 (2520 metric) package must dissipate. The iron-powder core handles the flux density without saturating, but the winding loss sets the temperature rise at rated current. The DCR increases with temperature, so the effective current limit at 125°C is lower than the 25°C rating — derate per the manufacturer's curve for the actual ambient. ## Shielding and layout fit Shielded construction contains the magnetic field within the component body — adjacent traces and other inductors on a dense board see minimal coupling. This is critical when the inductor sits near a sensitive analog rail or another switching node. Flat-wire winding packs more copper cross-section than round wire in the same volume, which is how this part achieves 4.8 A in a 1008 case.","metaTitle":"Murata DFE252010F-R33M=P2 Shielded Power Inductor, 330 nH","metaDescription":"Active Murata DFE252010F-R33M=P2 shielded wirewound inductor, 330 nH ±20%, 4.8 A rated current, 21 mOhm DCR, 1008 package.
