The Q factor of 60 at 100 MHz indicates moderate energy storage efficiency at that frequency; for a narrow-band tuned circuit, the 3 dB bandwidth is proportional to 1/Q, so expect a bandwidth of about 1.7% of the center frequency. ## Drum core wirewound in a 1206 body The ±5% tolerance on 500 nH gives a guaranteed range of 475 nH to 525 nH — tight enough for most resonant tank and filtering applications where the inductance value directly sets the frequency.","metaTitle":"Murata LQH31HNR50J03L Drum Core Inductor, 500 nH, 260 mA","metaDescription":"Murata LQH31HNR50J03L wirewound ferrite-core inductor, 500 nH ±5%, 260 mA, 440 mOhm DCR.
