The 6.2 Ohm max DCR sets the DC conduction loss — at 70 mA the I²R drop is about 30 mW, negligible in a signal path but a factor if this inductor sits in a DC bias feed for an RF amplifier or a low-power LC filter. The unshielded construction means the flux field extends beyond the core — keep sensitive traces or adjacent inductors at least one part-width away to avoid coupling. The ferrite core material and 8.5 MHz self-resonant frequency make this part usable up to a few MHz before the impedance becomes capacitive. ## Q factor and frequency ceiling Q is specified at 40 at 1 MHz — a moderate figure for a wirewound of this inductance. The self-resonant frequency of 8.5 MHz means the effective inductance starts rolling off well before that; for a clean LC tank or a low-pass filter, keep the operating frequency below about 2 MHz to stay in the inductive region.","metaTitle":"Murata LQH32MN820J23L 82 µH Inductor, 70 mA, 1210","metaDescription":"Murata LQH32MN820J23L drum core wirewound inductor, 82 µH ±5%, 70 mA rated current, 6.2 Ohm DCR, 1210 SMD.
