Its 78 mOhm maximum DCR means the I²R loss at full rated current is about 78 mW — a figure that matters when you're budgeting thermal rise in a compact 1210 package. The 100 MHz self-resonant frequency (SRF) puts it well above the switching frequency of most buck converters (typically 500 kHz to 2 MHz), so the inductor behaves as a pure inductive element in-band. ## Unshielded construction — what it means for your layout This is an unshielded inductor — the magnetic flux radiates from the core. On a dense PCB, that means the inductor should be spaced away from sensitive analog traces, especially those carrying signals above a few MHz where coupling is more efficient. The 1210 (3225 metric) footprint is standard, but the unshielded nature means you cannot simply drop it into a layout that expects a shielded part without checking the stray field impact on adjacent circuitry.","metaTitle":"Murata LQH32DN1R0M53L 1 µH Unshielded Wirewound Inductor","metaDescription":"Murata LQH32DN1R0M53L drum core wirewound inductor, 1 µH ±20%, 1 A rated, 78 mOhm DCR, 1210 SMD.
