33 µH shielded inductor for automotive DC-DC
The Murata LQH2HNH330J03L is a 33 µH shielded wirewound inductor in the LQH2 series, qualified to AEC-Q200 for automotive-grade reliability. Rated for 85 mA continuous current with a DCR of 3.6 Ω, it suits low-current DC-DC converter output filters and power-line conditioning in engine bay or cabin electronics.
AEC-Q200 and temperature range
AEC-Q200 qualification means the inductor passed the stress tests for automotive applications — thermal shock, moisture resistance, and mechanical shock — so it fits under-hood or chassis-mounted modules.
Shielding and self-resonant frequency
The shielded construction reduces radiated EMI from the magnetic field, critical when the inductor sits near sensitive analog or RF circuitry on the same board. Self-resonant frequency is 17 MHz, well above the typical switching frequencies of automotive DC-DC converters (400 kHz–2 MHz), so the inductor behaves as a pure inductive element in-band.
