Rated 250 µH ±20% at 1 MHz test frequency, with a self-resonant frequency of 2 MHz — the inductance holds flat well below SRF, but above 2 MHz the component behaves capacitively and should be avoided in filter designs targeting that band. DC resistance is 9.6 Ohm maximum; at the 140 mA rated current the I²R loss reaches roughly 188 mW, which for a 1212 body means the temperature rise is dominated by the copper loss at full load. Saturation current is specified at 110 mA — the inductance drops by 20 % at that point, so for applications requiring the full 250 µH under bias, the operating current should stay below 110 mA. ## Lifecycle and supply position Murata lists the LQH3NPN251MGRL as Last Buy — the manufacturer has announced end-of-life and will accept final orders within a defined window. No official successor order code is recorded in the lifecycle data. For existing BOM lines, the last-time-buy quantity should cover the remaining production run; for new designs, a pin-compatible 250 µH shielded inductor in the 1212 footprint from the same or a competing series should be evaluated.","metaTitle":"Murata LQH3NPN251MGRL Shielded Power Inductor, 250 µH","metaDescription":"Murata LQH3NPN251MGRL, 250 µH shielded wirewound inductor, 140 mA, 9.6 Ohm DCR, 1212 (3030) package.
