The 114 mOhm max DCR keeps conduction losses low for the current rating, while the 1.35 A saturation current (Isat) provides headroom for transient peaks without hard saturation. The 1212 (3030 Metric) footprint and 1.20 mm seated height suit space-constrained power rails on compact PCBs. ## Current rating and saturation margin Rated 750 mA continuous with a 1.35 A saturation current — the 1.8× ratio means the inductor stays in its linear inductance region under most load transients, critical for maintaining ripple current in a buck converter. The 114 mOhm DCR at 750 mA produces about 64 mW of copper loss — acceptable for most portable and embedded supplies without active cooling. Surface-mount 1212 (3030 Metric) package with ferrite core and shielded construction — the shield reduces radiated EMI into nearby traces, a practical advantage when the inductor sits next to a switching node.","metaTitle":"Murata LQH3NPN3R3MJRL 3.3 µH Shielded Inductor, 750 mA","metaDescription":"Murata LQH3NPN3R3MJRL drum core wirewound inductor, 3.3 µH ±20%, 750 mA, shielded, 1212 package.
