Power rail filtering in automotive ECUs
The Murata LQH2MPZ6R8MGRL is a 6.8 µH wirewound ferrite-core inductor in the LQH2 series, sized for DC-DC converter output filtering and power supply decoupling on automotive PCBs. Rated 530 mA continuous with a saturation current floor of 730 mA, the part handles steady-state load current while holding inductance up through transient peaks. Max DC resistance is 864 mOhm — the I²R loss at full rated current is about 240 mW, a manageable figure for the 0806 footprint in forced-air or moderate convection environments.
AEC-Q200 grade and temp range
Qualified to AEC-Q200, the part is stress-tested for automotive-grade reliability — thermal shock, moisture resistance, and mechanical shock per the passive-component stress qualification standard.
0806 footprint and shielded construction
Shielded ferrite core contains the magnetic flux, reducing radiated EMI into nearby signal traces and keeping the inductor from coupling noise into sensitive analog or RF sections.
Self-resonant frequency margin
Self-resonant frequency is 35 MHz — well above the 1 MHz test frequency and typical DC-DC switching frequencies in the 500 kHz to 3 MHz range, so the inductor behaves inductively in-band without capacitive roll-off.
