Below about 10 MHz the part behaves as a pure inductor; above that the inter-winding capacitance starts to dominate and the impedance rolls off. For a buck converter switching at 2-3 MHz this is well within the inductive region, but if you're using it as a high-frequency choke above 20 MHz the effective inductance drops fast. ## Unshielded trade-off and board placement Being unshielded, the LQH32CN4R7M23L radiates a stray field that can induce noise in nearby loops. On a dense board with a mixed-signal section, a shielded alternative in the same footprint would contain the flux.","metaTitle":"Murata LQH32CN4R7M23L 4.7 µH Unshielded Inductor, 450 mA","metaDescription":"Murata LQH32CN4R7M23L drum core wirewound inductor, 4.7 µH ±20%, 450 mA, 260 mOhm DCR, unshielded, 1210 package.
