If this inductor is on your BOM, now is the time to secure lifetime buy quantities or qualify a replacement. ## 1.5 µH, 155 mA — fits DC-DC output filtering and bias decoupling The 1.5 µH inductance at 1 MHz test frequency with ±5% tolerance suits low-current DC-DC converter output filters and bias line decoupling where tight inductance tolerance keeps the cutoff frequency stable. Rated 155 mA continuous with a maximum DC resistance of 1.3 Ohm — the DCR sets the I²R heating floor, so at full rated current the self-heating is about 31 mW, well within the 85°C ambient limit. ## 1206 footprint, unshielded — board-layout considerations Drum core wirewound on a ferrite core — the wirewound construction gives higher Q (35 at 10 MHz) than multilayer ferrite beads, making it a better choice for tuned circuits or low-loss filtering up to the 75 MHz self-resonant frequency.","metaTitle":"Murata LQH31MN1R5J03L Inductor, 1.5 µH, 155 mA, 1206","metaDescription":"Murata LQH31MN1R5J03L drum core wirewound inductor, 1.5 µH ±5%, 155 mA, 1.3 Ohm DCR, 1206 SMD.
