220 nH wirewound inductor for RF and power filtering
The LQH31CNR22M03L: Rated for 850 mA continuous current with a maximum DC resistance of 140 mOhm, the part suits low-voltage power rail filtering and RF decoupling where the DC bias stays below the saturation knee. 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.
