DC resistance is 156 mOhm max, which at 710 mA gives a self-heating I²R loss of about 79 mW — negligible in free air but relevant in a dense 1210 array where adjacent components share the thermal budget. The unshielded construction means the flux couples into nearby traces; keep sensitive analog or RF routing at least one part width away. ## 1210 footprint, 1.7 mm seated height The ferrite core and wirewound construction mean the part is not self-shielding — the unshielded flux can couple into a ground plane underneath, so a solid copper pour under the inductor is fine, but avoid routing a sensitive signal trace directly below it on an inner layer. Surface-mount on Tape & Reel (TR) or Cut Tape (CT) — the reel quantity is not specified here, but the 1210 footprint is standard for pick-and-place.","metaTitle":"Murata LQH32CN3R3M53L Drum Core Inductor, 3.3 µH, 710 mA","metaDescription":"Active Murata LQH32CN3R3M53L wirewound inductor, 3.3 µH ±20%, 710 mA, 156 mOhm DCR, 1210 package.
