The self-resonant frequency of 250 MHz sets the usable bandwidth ceiling — above this frequency the inductor behaves capacitively, limiting its application in high-frequency matching networks. ## Last Buy lifecycle — procurement window is closing Murata has placed the LQH31CNR22M03L in Last Buy status, meaning the manufacturer will cease production after the final order window closes. Buyers should secure lifetime-buy quantities or qualify a substitute inductor with matching 220 nH, 850 mA, and 1206 footprint before supply dries up. ## Ferrite core and unshielded construction Inductance is tested at 1 MHz, which is the standard reference frequency for this value range; the ±20% tolerance band is typical for power-grade ferrite inductors where the DC bias and temperature effects dominate the actual in-circuit value.","metaTitle":"Murata LQH31CNR22M03L 220nH Inductor, 850mA, 1206","metaDescription":"Murata LQH31CNR22M03L drum core wirewound inductor, 220 nH ±20%, 850 mA, 140 mOhm DCR, 250 MHz SRF, 1206 package.
