It delivers 1.5 mH of inductance at 1 kHz test frequency, with a ±5% tolerance that keeps the value tight enough for LC filter and decoupling circuits where the inductance is part of the cutoff calculation. Rated for 40 mA continuous current, with a maximum DC resistance of 37 Ohms. The 40 mA figure is the current at which the inductance typically drops by 10% — stay below it if you need the full 1.5 mH. Self-resonant frequency is 1.6 MHz, and the Q factor is 40 at 252 kHz. Above 1.6 MHz the inductor behaves capacitively, so it is best suited for switching frequencies below 1 MHz — think EMI input filters, low-frequency DC-DC output chokes, or audio-band noise suppression. ## 1812 SMD footprint and hand-solder friendliness The 1812 footprint is large enough for hand soldering with a fine-tip iron — no hot-air or reflow oven required for prototyping. The unshielded construction means the magnetic field extends outside the body, so keep it away from sensitive analog traces or other inductors that might couple. Available in tape-and-reel or cut-tape options, making it equally suitable for pick-and-place assembly or bench work. The ferrite core material gives stable inductance over temperature up to 85°C, with a typical temperature coefficient of +100 to +250 ppm/°C.","metaTitle":"Murata LQH43MN152J03L Inductor, 1.5 mH, 40 mA, 1812","metaDescription":"Murata LQH43MN152J03L drum core wirewound inductor, 1.5 mH ±5%, 40 mA, 37 Ohm DCR, 1812 SMD.
