3.3 µH wirewound for power rail filtering
The Taiyo Yuden LBC2016T3R3M is a 3.3 µH drum core wirewound inductor in the LB, C Type series, built on a ferrite core and housed in an 0806 (2016 Metric) surface-mount package. Rated at 410 mA with a DC resistance of 270 mOhm, it targets low- to moderate-current DC-DC converter input/output filtering and decoupling applications where the inductance value and current rating align with the load budget.
Current rating and DCR impact on efficiency
The 410 mA current rating sets the continuous load ceiling; exceeding it drives the core into saturation and collapses the inductance. Unshielded construction means the magnetic field radiates into the surrounding board area; adjacent traces carrying sensitive analog signals or high-impedance nodes need keep-out distance or a ground-plane isolation slot to avoid coupling. The self-resonant frequency of 55 MHz indicates the inductor behaves inductively well above typical switching frequencies in the hundreds of kHz to a few MHz range.
