Self-resonant frequency is 200 MHz and Q is 30 at 25 MHz, both measured at 1 MHz test frequency — the SRF ceiling means this part is usable as a choke or filter element well into VHF bands, but above 200 MHz the inductive reactance collapses and the part behaves capacitively. ## Package and assembly compatibility Supplied on tape and reel, so it feeds directly into a pick-and-place machine without a reel-change interruption for prototype or production runs. Unshielded construction — the magnetic field radiates from the drum core, so adjacent traces carrying sensitive analog signals or high-impedance nodes should be kept at least one part-width away to avoid parasitic coupling.","metaTitle":"Murata LQH31MNR47K03L Inductor, 470 nH, 215 mA, 1206","metaDescription":"Murata LQH31MNR47K03L drum-core wirewound inductor, 470 nH ±10%, 215 mA rated current, 830 mOhm DCR, 1206 SMD.
