It delivers 3.3 µH inductance at 1 MHz test frequency with ±5% tolerance, rated for 800 mA continuous current. ## DC resistance and power budget Maximum DC resistance is 92.4 mOhm, which at 800 mA produces about 59 mW of I²R loss — well within the 1812 package's dissipation capability and a non-factor for most power rail filtering or DC-DC output stages. The self-resonant frequency sits at 47 MHz, so the inductor behaves as an inductor well into the HF band — useful for buck converter switching frequencies up to a few MHz where the SRF provides adequate margin above the switching fundamental. ## Active and available Production status is Active per Murata's lifecycle record.","metaTitle":"Murata LQH43NH3R3J03L Inductor, 3.3 µH, 800 mA, 1812","metaDescription":"Murata LQH43NH3R3J03L drum core wirewound inductor, 3.3 µH ±5%, 800 mA, 92.4 mOhm DCR, AEC-Q200, 1812 package.
