At 300 mA the I²R loss is about 40 mW — fine for a decoupling or low-power filter leg, but the temperature rise at the rated current is worth checking if the part sits near a hot regulator or in a confined enclosure. The self-resonant frequency is 26 MHz, so the inductive region extends well past the switching frequencies of most DC-DC converters (typically 500 kHz to 2 MHz) — it behaves as an inductor in that band, not a capacitor. ## Unshielded construction — where it fits and where it doesn't This is an unshielded inductor — the magnetic field radiates from the drum core. In a layout, keep a gap of at least one component width to adjacent sensitive traces or other magnetics to avoid coupling noise. The 1210 (3225 metric) footprint is standard, but the 'Nonstandard' package note means the pad geometry may differ slightly from a generic 1210 chip inductor — confirm the land pattern against the datasheet drawing before the reflow stencil is cut. Wirewound construction gives a higher Q and better current handling than a multilayer ferrite chip at this inductance value — the trade-off is the radiated field and a slightly taller profile (2.2 mm seated height).","metaTitle":"Murata LQH32CH100K23L 10 µH Inductor, 300 mA, 1210","metaDescription":"Murata LQH32CH100K23L drum core wirewound inductor, 10 µH, 300 mA, 440 mOhm DCR, unshielded, 1210 package.
