Rated for 1.28 A continuous with a DCR of 38.4 mOhm max, this part handles the ripple current in a buck converter's output filter without excessive copper loss — the low DCR keeps the I²R heating within the 105°C operating ceiling. ## Saturation margin and SRF Saturation current (Isat) is 2.7 A, more than double the rated current — the core stays linear across the full load range, so inductance holds steady even under transient peaks. Self-resonant frequency is 130 MHz, well above the switching frequencies of typical 1–2 MHz DC-DC converters; the inductor behaves as a pure inductance in the passband, not a parasitic resonator.","metaTitle":"Murata LQH3NPNR68NJRL Drum Core Inductor, 680 nH, 1.28 A","metaDescription":"Murata LQH3NPNR68NJRL shielded wirewound inductor, 680 nH ±30%, 1.28 A, 38.4 mOhm DCR, 1212 package.
