It is rated for 710 mA DC current with a maximum DC resistance of 156 mOhm, so the resistive voltage drop at full rated current is about 111 mV — a factor to budget in low-voltage rails. The self-resonant frequency of 50 MHz means the inductor maintains its inductive impedance up to that point; above 50 MHz the parasitic capacitance dominates and the part behaves like a capacitor. This makes it suitable for DC-DC converter output filters and low-frequency EMI suppression where the switching fundamental stays well below 50 MHz. The 1210 (3225 Metric) footprint is a common size for automated pick-and-place assembly.","metaTitle":"Murata LQH32CH3R3M53L Inductor, 3.3 µH, 710 mA","metaDescription":"Murata LQH32CH3R3M53L drum-core wirewound inductor, 3.3 µH ±20%, 710 mA, 156 mOhm DCR, 50 MHz SRF, -40°C to 85°C.
